A wastewater treatment facility treats the sewage that it receives
from the collection system. To treat the undesirable contents in the
sewage, a variety of processes are used -- mechanical, biological and
chemical systems. Many modern treatment processes are multistage
systems. The first wastewater treatment plant on the European continent was put into operation in 1882 in Frankfurt, Germany.
System components
Storm Water
There are two major types of collection systems — the combined
sewer system, usually found in older cities, where both storm and
sanitary sewage are in a common system and the conventional separated system where there are separate sewers for the storm and sewage systems.
Combined Sewers
In combined sewer systems, the storm water and wastewater are fed
into a common collection system. These systems often feature an
overflow or equalization basin to relieve the peak flows experienced
during heavy storm periods. These basins can be installed either remotely in the collection system or at the treatment facility. Alternatively, the entire treatment facility must be oversized to process the
hydraulic peak flow.
Conventional Separated Sewers
Where there are conventional separated sewers, the sewage is fed to
a separate wastewater collection system while the storm water is
collected in another system. Storm water in these applications is
treated, if necessary, and directly discharged.
The influent flow in combined sewer systems can carry large amounts
of contaminants due to the scouring effect of the oversized collection system during a storm event. These contaminants can later lead
to major odor problems in an overflow or equalization basin. Wilo SR
series jet aerators can provide a solution to this problem. These aerators are equipped with Wilo submersible pumps and can aspirate air
and add oxygen to the sewage in the basin and keep all solids in suspension.
The Treatment Process
1. Preliminary Treatment
Screening
In preliminary treatment process, the sewage is usually pumped
through a mechanical or manual bar screen. The larger solids, such as
tampons, rags, condoms, cotton swabs and other materials are removed by the screen. Finer spacing on the screens can offer greater
removal of the materials that can negatively wear the downstream
equipment, but greatly increases the volume of material, including
some organics, being removed.
A differentiation is made between fine mechanical screens (openings
of less than ½”) and coarse screens (openings of ¾” and larger). The
material removed by a fine screen is often washed to remove any fecal matter. The water is then removed by a screenings press and returned to the treatment process. The dewatered screenings are disposed of in a landfill, incinerated or composted into fertilizer.
Grit removal
A grit chamber is a sedimentation tank with a fixed detention time.
Its purpose is to remove coarse inorganic contaminants that will settle from the sewage-like grit, sand and small debris. These contaminants, especially grit, lead to equipment malfunctions due to wear
and clogging. The grit removal system must be designed to remove
the inorganic material without removed the organic material which
provides a food source in subsequent treatment processes.
Possible designs include:
Another option for keeping solids in suspension in overflow or equalization basins is using our Wilo TR series submersible mixers. These
units can be rail mounted and installed directly to the tank base or
wall and generate sufficient turbulence to prevent the settling of solids.
• Long, narrow tank utilizing only gravity for settling
• Aerated grit chamber in a long, narrow tank where grease and oil are
removed on the surface
• Round grit chamber
• Deep grit chamber
In many conventional designs, an aeration device, like air diffusers
being fed by a remote blower, is mounted on the floor of the basin.
The added air lowers the density of the liquid portion of the sewage,
but is unable to penetrate the grit and similar particles. The heavier

mineral components then settle out in the hopper section of the basin bottom.
In modern systems, the collected grit is subsequently washed to remove the organic constituents to reduce odor and make recycling of
the grit material (road construction, for example) possible.
Pumping the collected grit from the grit chamber causes high wear
demands on the selected pumps. Special attention must be paid to
the materials of construction of the pumps. Additionally, often the
pumps must be able to partially re-suspend the grit in order to successfully pump it from the basin. Wilo series FA type WR submersible
pumps with mixer heads are well suited for this application. The mixer
head affects only the grit in the area of the pump inlet. Due to the
limited zone of influence, the settling of the majority of the grit is unaffected. As the grit material is very abrasive, Wilo offers their grit
pumps in their Abrasit (chilled cast iron) which provides excellent
wear resistance and hardness (63 HRC).
2. Biological Treatment
In this step, the undesirable sewage constituents are biologically degraded by microorganisms. There are several types of treatment processes: activated sludge, tricking filters, and rotating biological contactors among those in use. As an example, the activated sludge
process, which is in wide application throughout the world, will be
examined more closely below.
Activated sludge process
In the activated sludge process, organic sewage constituents are oxidized to carbon dioxide and water in activated sludge basins by aerating the mixed liquor (combination of activated sludge and sewage).
Simultaneously, the nitrogen (ammonia related) compounds are oxidized to form nitrate in a process called nitrification, which is the first
step in the total nitrogen removal.
The second step in total nitrogen removal is denitrification. Denitrification is a process of converting nitrates to nitrogen gas and consequently occurs in an anoxic (no dissolved oxygen) condition — this
requires a separate treatment section. This denitrification process is
an excellent application for Wilo series TR submersible mixers as they
are able to keep the mixed liquor in suspension without adding any
oxygen — this keeps the rate of denitrification at an optimum rate.
The activated sludge process is a continual process where the activated sludge and raw sewage are mixed on a continuous basis. Further treatment can be achieved to remove phosphorus either through
chemical additions or by biologically releasing the phosphorus
through the use of an anaerobic (no dissolved oxygen and near zero
nitrates) process tank — this requires a separate treatment section.
This anaerobic process is an excellent application for Wilo series TR
submersible mixers as they are able to keep the mixed liquor in suspension without adding any oxygen — this keeps the rate of biological phosphorus release at an optimum rate. Phosphorus is later removed by subsequent treatment processes.
Primary Clarification
The hydraulic detention in the primary clarifier, when used, is much
longer than that of the grit chamber. This extended time allows the
primary clarifier to settle smaller and lighter particles than those settled in the grit chamber. Approximately 30 % of the organic matter
can be removed through primary clarification. Grease and other floatable materials remain on the surface of the clarifier and can be removed by skimming.
Primary sludge from the clarifier is often transferred to gravity thickeners. Gravity thickeners thicken this sludge and waste sludge from
the activated sludge system. The thickened sludge is created by removing as much of the fluid as possible through gravity; the decanted water is returned to the treatment process and the remaining
thickened sludge is subsequently sent to digestion.
In modern biological nutrient removal processes designed for nitrogen removal, primary clarification is often omitted of minimized. This
keeps the required organic substances intact for the downstream denitrification process. Additionally, most extended aeration facilities
do not use primary clarifiers.
7
Planning guide
Submersible mixers
Secondary Clarification
The secondary clarifiers, along with the aeration basins and any anoxic or anaerobic tanks, form the process unit. In the secondary clarifiers, the activated sludge is separated from the mixed liquor from
the aeration or other treatment basin. Most of this activated sludge is
returned (RAS) to the process in order to keep the concentration of
microorganisms in the process at an optimal level. A portion of the
activated sludge is wasted (WAS) — it is removed from the process
train and sent to the gravity thickeners or other solids processing
equipment.
In many secondary or advanced treatment processes, the mixed liquor that has been processed is recycled to the head of the biological
process train. This recycle flow and the return activated sludge flow
can often be delivered by a low head axial flow pump like the Wilo series RZP recirculation pump.
The secondary sludge can have settling difficulties. Through the
growth of filamentous microorganisms, sludge bulking can occur and
floating sludge can contaminate the effluent.
4. Sludge Treatment
There are 2 basic forms of digestion—aerobic digestion and anaerobic digestion. Aerobic digestion uses the addition of oxygen and decanting excess water to reduce the volatile solids content of the
sludge.
In an anaerobic digestion, volatile solids are reduced and combustible
gas is formed. The combustible gas can often be used to produce
heat or electricity to cover the requirements of the treatment facility.
After digestion, and sometimes thickening, the sludge is prepared for
disposal. The liquid sludge can be land applied. The sludge can be dewatered and then disposed of in a landfill, composted into fertilizer or
incinerated.
Treatment processes
Preliminary Treatment: The preliminary treatment stage usually
consists of mechanical processes. Approximately 20 to 30 % of the
solid, undissolved floating and suspended matter is removed. In advanced and industrial wastewater treatment processes, adsorption,
filtration and stripping can be used.
3. Chemical Addition and Disinfection
Following the biological treatment process, disinfection of the remaining microorganisms occurs through ultraviolet disinfection or
the addition of chlorine or ozone. Additionally, chemical addition to
remove phosphorus or precipitate other compounds from the effluent is possible. The disinfected sewage effluent is then discharged to
a receiving stream.
Biological Process: Biological processes are used in municipal treatment systems to degrade the organic contamination of sewage in
aerobic, anoxic and anaerobic wastewater treatment. In aerobic
treatment, sewage is degraded such that the end products are principally water, carbon dioxide, nitrate, phosphate and sulfate.
In anaerobic wastewater treatment, the compounds are converted to
organic acids, methane and carbon dioxide. Carbon compounds act as
a food source for nitrification and denitrification, which provide a
means for removing nitrogen which is a component of commercial
fertilizers. Phosphorus, another ingredient in commercial fertilizers, is
often removed using biological nutrient removal.
Chemical Addition and Disinfection: After the biological treatment
process, the effluent can be treated with chemical addition for removal of phosphorus and other compounds. The effluent is also disinfected to remove any remaining contaminants.

management of activated sludge systems, the phosphorus absorption in
the biomass can be optimised (Bio-P). Thus, less flocculating agent is required to eliminate phosphorus. The basic objective is always to convert
the sewage constituents to be removed by means of biological processes
(respiration, biomass growth) into forms which can be removed from the
sewage by sedimentation or stripping (gaseous expulsion) and also are as
harmless as possible.

Load parameters
The load of waste water treatment systems is determined according
to the total number of inhabitants and population equivalents (PT).
This is the sum of the actual inhabitants (population, P) and the population equivalent (PE). The population equivalent is the agreed
quantity of sewage emissions assumed for one "standard inhabitant".
For commercial, industrial and agricultural production, the loads are
specified with reference to the production amounts (e.g. 10 PT
BOD5 per hectares vineyard acreage). It is to be observed, however,
that the ratios between the individual parameters can vary. Sewage
can have a higher concentration (less sewage volume for the same
amount of contamination), or it can be rich in organic carbon compounds and have fewer nutrients.
The content of biodegradable substances is quantified with the sum
parameter Biochemical Oxygen Demand, or BOD for short. As a rule, it
is measured in milligrams of the biochemical oxygen consumption
within 5 days under standard conditions of 68 °F (20 °C) and is referred to as BOD5. For biotic degradation, a nutrient ratio of BOD5:N:P
of about 100:5:1 is favourable in order to supply the microorganisms
with a sufficient amount of nitrogen and phosphorus. This is based
on the assumption that about 50 % of the degraded organic substances are used for biomass growth and that the biomass consists of
about 10 % nitrogen and about 2 % phosphorus.
The total number of inhabitants and population equivalents, or PT for
short, is equivalent to the following values:
Amount of sewage - Europe
Formerly, a wastewater value of 40 to 53 US gpm (150 to 200 litres)
per inhabitant and day was assumed as the load for a sewage treatment system. The wastewater value is roughly equivalent to the water consumption. For new planning or advance planning, the location-specific water consumption is determined and an estimation is
attempted to be made for the future. Normally, wastewater volumes
of around 34 US gpm (130 litres) per inhabitant and day are assumed.
This value takes the usual values for dense sewage networks in Central Europe into account. For dimensioning the water treatment system, however, usually an additional amount is taken into account for
external water (leaky channels, feed from drainage, etc.). This can
amount to up to 100 % of the wastewater value. The volume of external water refers to the connected sealed surface and should not be
more than ∅.∅4 US gpm/s*hectare (0.15 l/s*hectare).
In the case of mixed sewer systems (rainwater and wastewater in one
channel), the corresponding additional amounts for processing the
rainwater are to be taken into account, which are usually assumed to
be 100 % of the daily peak value during dry weather.
For the hydraulic calculation (number and size of the pumps) of the
water treatment system, the daily load curve is also significant. For
dimensioning therefore, the average daily sewage amount is not to
10
be divided by 24 hours, but instead by a smaller value (10 to 14) for
the maximum hourly value.
Amount of sewage - USA1)
In the United States, per capita wastewaster volume ranges from 50
to 250 gallons (190 to 950 liters) per day. A common design criteria is
100 to 120 gallons (380 to 450 liters) per day. Typical domestic
wastewater contains ∅.24 lbm (110g) of suspended solids and ∅.17
to ∅.20 lbm (77 to 90g) of BOD.
Degree of contamination
BOD5
For the BOD5 value, i.e. the biochemical oxygen demand during a
measured time of 5 days under standard conditions, the oxygen demand is measured which arises due to the oxidation of organic substances by aerobic microorganisms. It belongs to what are called sum
parameters, since the degradation of single compounds cannot be
determined with it.
2.12 oz.av (60 g) per inhabitant and day are assumed as the normal
BOD5 value.
Of this, about ∅.70 oz.av (20 g) can be removed by means of sedimentation during primary treatment.
Chemical oxygen demand
The chemical oxygen demand, or COD for short, is also among the
sum parameters, since no individual compounds can be quantified
with it. It is determined by means of oxidation of the sewage contents by potassium chromate and measures the oxygen demand for
oxidising a majority of organic substances. If there are also oxidisable
inorganic compounds, such as sulphites, in the sewage, these are also
registered as COD.
This parameter is also used for balancing the system.
For the COD, a value of ∅.26 lbm (120 g) per inhabitant and day is assumed.
Nitrogen
In untreated sewage, nitrogen exists mainly in the form of organic
compounds (e.g. in proteins, nucleic acids, urea) and in the form of

Cost and energy efficiency of Wilo submersible mixers
The right choice

For the operator of water treatment systems, it is not easy to make a
decision for the most economical mixing system. The lowest capital
cost should not be the decisive factor under any circumstances. Total
life cycle costs for the mixers should be considered taking all relevant
influencing factors into account. This only makes sense, however,
when all factors involved in the mixing process have been considered.
These include:
• Capital costs
• Installation and commissioning costs
• Energy and operating costs
• Maintenance and repair costs
• Operating failure costs
• Disposal costs
Only once the above-listed influencing factors have been expressed
in present worth, is it possible to make an objective mixer comparison.

*in accordance with DIN ISO 21630
Energy costs
Since many mixer applications require continuous operation, power
cost is often the highest operating expense. The decisive parameters
of submersible mixers are thrust (F*) and the consumed electric power at the duty point (P1.1*).
This allows important power parameters to be determined.
• Specif. thrust output [N/kW] = thrust [F] / power [P1.1]
This parameter can be used to compare the energy efficiency of different products.
• Specif. power density = power [P1.1ges] / tank volume
This parameter is for the comparison of different mixer designs and
provides information on the energy costs to be expected.
Cost calculation
A small calculation example shows that considerable cost savings are
possible with a mixer design optimised in terms of energy.
Tank volume: ∅.78 Mgal (2950 m3)
Mixer selection:
• According to investment costs: 3.63 W/m3 (specif. power density)
• Optimised according to operating costs: 1.7 W/m3 (specif. power
density)
The optimisation according to operating costs brings an advantage of
1.93 W/m3, which corresponds to a savings for this tank of
approx. 7.6 hp (5700 W).
At an annual operating time of 8760 hours and a price of
$ 0.11 per hp/h, that means savings of $ 7320 per basin per year.
These savings are possible by using highly efficient submersible mixers from Wilo.

Ceram coating
Modern corrosion and abrasion protection
Planning guide Submersible mixers Ceram coating Subject to change without prior notice 12/2010 WILO SE Wilo Catalog Sewage treatment - Submersible mixers - 60 Hz
Units that come into contact with the fluid are subject both to highly
corrosive as well as abrasive influences. For this, Wilo offers its Ceram
coating. This provides reliable protection against this type of stress.
Normal heavy corrosion protection methods, such as zinc dust priming with three coats of tar epoxy resin are called onion layer models.
The advantage of zinc dust priming is that the zinc dust sacrifices and
the zinc carbonate can seal microscopic cracks. This is referred to as
the self-healing effect of the coating. The disadvantage is that the
wet adhesion of this zinc dust priming isn't very high. Because of the
onion layer model of conventional solvent-containing coatings, the
adhesive force depends on the quality of the individual layers.
Ceram coatings are available in four different quality levels. These are
distinguished in terms of their resistance to abrasive corrosion. While
corrosion resistance is very good for all four quality levels, resistance
to abrasion increases the higher the ordinal number (C0 = low protection from abrasion; C3 = very good protection from abrasion) of
the coating, since coarser aluminum particles are processed. The individual layers get thicker and the mixture of large, medium-sized
and small aluminum oxide particles is such that even in the case of
abrasion with fine sand, the coatings are very stable.
• Ceram C0: The coating is applied using the airless method in one layer of 0.016" (0.4 mm).
• Ceram C1: The coating is applied with a paintbrush and may consist
of up to three layers. The layer thickness is 0.059" (1.5 mm).
The Ceram coating, on the other hand, is based on the diamond model. It unifies the positive properties of two materials by combining
aluminum oxide particles in one polymer matrix. The aluminum oxide
particles are enclosed in the matrix. Thus, there are no predetermined
breaking points and the adhesion is very high, e.g. in the case of Ceram C0 2175 psi (15 N/mm2). Since Ceram is solvent-free, these
coatings can be applied with one layer.
• Ceram C2: The coating is applied with a trowel. The layer thickness is
0.059" (1.5 mm) and consists of one coat.
• Ceram C3: The coating is applied with a trowel. The layer thickness is
0.118" (3 mm) and consists of one coat. For tight gaps/clearance, a
mechanical process is necessary.
For use in special fluids, the individual Ceram qualities can be combined with one another, e.g. C2 + C1.

Ceram coating
The Ceram coating is also very well suited for use in maritime environments. For its Ceram C0 coating, Wilo grants a guarantee of 5
years for use in seawater. The prerequisite is that the coating is intact
Increase efficiency, reduce costs
Since water is in short supply, the proportion of contaminants is increasing relative to the amount of water. This means that the concentration of corrosive and abrasive constituents is higher.
Sewage units are always exposed to this aggressive fluid. Corrosion
and abrasion affect the surfaces and material structures of the units,
sometimes with considerable impairments to the material, and thus
also the performance.
This significantly reduces the hydraulic efficiency. This results in the
units having an increased current consumption. On the other hand,
the pumps no longer work at their optimum, the radial forces increase, there is more stress on the bearings and mechanical seals, and
the service life of the machines is reduced.
When standard materials are used, such as grey cast iron, under high
stress, it may be necessary to exchange the components already after
500 hours of operation. Ceram coatings allow the service life to be
increased by a factor of 4, and this at the same high efficiency, which
means minimum energy costs.
If one takes the overall costs over the entire service life of the pump
into account, the investment costs for a unit coated with Ceram are
less than 10%, and thus negligible. On the other hand, there is a high
savings potential due to the fact that fewer repairs are required, resulting in a significant reduction of system downtimes. The amortisation is then usually quickly reached due to the higher efficiency.
Use of the various Ceram qualities
• Ceram C0 is used for the complete outer and inner coating. It's ideally
suited for corrosion protection.
• Ceram C1 is used for the inner coating of pump components. The
main field of application is the coating of the impeller and the suction
port .
• Ceram C2 and C3 are used for the inner coating of pump components.
The main field of application is the coating of the pump housing.
In order to guarantee protection even in especially aggressive and
corrosive fluids, the Ceram types are combined with each other, e.g.
C2 + C1 or C3 + C1.

Motor
Wilo-submersible motor of the T-series with standard connection for
an easy and efficient adaptation of the motor output. The motor heat
is given off directly to the fluid via the housing. The winding is
equipped with a temperature monitor. Large-sized grooved ball
bearings ensure long service life of the motor bearings.
Sealing
Double shaft sealing with large-volume sealing chamber to collect
leakage from the mechanical seal; available with external sealing
chamber electrode upon request. On the motor and fluid side, a corrosion- and wear-resistant mechanical seal made of solid silicon carbide material is used. A seal bushing ensures long-term corrosionprotected fit of the mechanical seal.
Cable
The power cable is a type H07 cable for heavy mechanical loads. The
power cable enters the motor housing through a water pressuretight cable entry with strain relief and bend protection.
Options
• Special voltages
• PTC thermistor temperature sensor
• External sealing chamber control
• Coating Ceram C0
• Ex-rated to ATEX, FM or CSA
Scope of delivery
• Submersible mixer with mounted propeller and cable
• Cable length per customer request
• Accessories per customer request
• Operating and maintenance manual
Dimensioning
A separate configuration must be carried out for each application to
ensure optimum generation of fluid current. Carefully follow the instructions for the supplied configuration when installing the units.
Commissioning
Operating mode S1 - permanent operation:
The submersible mixer must be immersed when operated. Surfacing
the propeller is strictly prohibited. In the case of fluctuating fluid levels, the system should switch off automatically if the degree of water
submersion drops below the minimum level. The power cables must
be installed in a way that these cannot be drawn into the propeller!

types, a seal bushing ensures long-term corrosion-protected fit of
the mechanical seal.
Cable
The power cable is a type NSSHÖU cable for heavy mechanical loads.
The power cable enters the motor housing through a water pressuretight cable entry with strain relief and bend protection. The individual
wires as well as the cable sheath are additionally sealed to keep out
fluids.

Application
Utilisation in activated-sludge tank and sludge tanks for:
• Generation of flow
• Suspension of solids
• Homogenisation
• Prevention of floating sludge layers
• Other areas of application in industry, agriculture and water supply
Propeller
2- or 3-blade propeller with a nominal propeller diameter of 20 inch
(500 mm) to 35.5 inch (900 mm). Non-ragging design made possible
by backward-curved incoming flow edge .
Motor
equipped with a temperature monitor. Large-sized inclined (not with
TR 80-1) and grooved ball bearings ensure long service life of the
motor bearings.
Sealing
Sealing is achieved through the use of a 3-chamber system (prechamber, gear chamber and sealing chamber). The large-volume prechamber and sealing chamber collect leakage from the mechanical
seal. If desired, the prechamber can be equipped with an external
sealing chamber electrode. The sealing between the fluid and the
prechamber, as well as between the gear and sealing chamber are realized by a corrosion-resistant and wear-proof mechanical seal made
of solid silicon carbide material. The sealing between the prechamber
and gear chamber as well as between the sealing chamber and motor
are realised by radial sealing rings. A seal bushing ensures long-term
corrosion-protected fit of the mechanical seal.
• Single-stage planetary gear for adjusting the propeller speed
• Propeller in steel, PUR or PUR/GFK version
Technical data
• Single-stage planetary gear
42
Gear
Single-stage planetary gear with exchangeable transmissions. The
gear bearings are dimensioned so that the resulting mixing forces are
absorbed and are not transferred to the motor bearings.

Motor
equipped with a temperature monitor. Large-sized inclined and
grooved ball bearings ensure long service life of the motor bearings.
Sealing
Sealing is achieved through the use of a 3-chamber system (prechamber, gear chamber and sealing chamber). The large-volume prechamber and sealing chamber collect leakage from the mechanical
seal. If desired, the prechamber can be equipped with an external
sealing chamber electrode. The sealing between the fluid and the
prechamber, as well as between the gear and sealing chamber are realized by a corrosion-resistant and wear-proof mechanical seal made
of solid silicon carbide material. The sealing between the prechamber
and gear chamber as well as between the sealing chamber and motor
are realised by radial sealing rings. A seal bushing ensures long-term
corrosion-protected fit of the mechanical seal.
Gear
2-stage planetary gear with exchangeable transmissions. The gear
bearings are dimensioned so that the resulting mixing forces are absorbed and are not transferred to the motor bearings.
Cable

Technical data
• Units are directly driven or with single-stage planetary gear
78
Propeller
2-, 3- or 4-blade propeller with a nominal propeller diameter of
8 inch (200 mm) to 31.5 inch (800 mm). Non-ragging design made
possible by backward-curved incoming flow edge . Propeller up to a
diameter of 10 inch (250 mm) have a patented helix hub.
Motor
equipped with a temperature monitor. Large-sized inclined (not with
RZP 80-2) and grooved ball bearings ensure long service life of the
motor bearings.
Sealing
RZP 20 … 25-2
leakage from the mechanical seal. If desired, the sealing chamber can
be equipped with an internal or external sealing chamber electrode.
On the fluid side, sealing is achieved using a corrosion- and wear-resistant mechanical seal made of solid silicon carbide material; on the
motor side, a rotary shaft seal is used. A seal bushing ensures longterm corrosion-protected fit of the mechanical seal.
RZP 50-3 … 80-2
Double shaft sealing with large-volume gate and sealing chamber to
collect leakage from the mechanical seal. If desired, the prechamber
can be equipped with an external sealing chamber electrode. On the
motor and fluid side, sealing is achieved using a corrosion- and wearresistant mechanical seal made of solid silicon carbide material. The
sealing between the individual chambers is achieved using rotary
shaft seals. A seal bushing ensures long-term corrosion-protected fit
of the mechanical seal.
Gear RZP 50-3…80-2
Single-stage planetary gear with exchangeable transmissions. The
gear bearings are dimensioned so that the resulting mixing forces are
absorbed and are not transferred to the motor bearings.
Cable
The power cable is a type H07 cable (with T 12 motor) or NSSHÖU
(with T 17 and T 20 motor) for heavy mechanical loads. The power
cable enters the motor housing through a water pressure-tight cable
entry with strain relief and bend protection. The individual wires as
well as the cable sheath are additionally sealed to keep out fluids.

AVU guide rail system... for Miniprop and Uniprop submersible mixers
The guide rail systems of type AVU… are flexible tripod systems for wall mounting. Due to a
ball joint made of plastic, even slight unevenness is smoothed out during installation. The
guide rail system absorbs the mixing forces which arise and transfer them to the structure. A
high resisting torque in the guide tubes, plastic linings in the sliding carriage and large-area
rubberised supports for large mixers guarantee high mounting security and long service life.
For optimum mixing results, the mixer can be swivelled horizontally. In connection with auxiliary hoisting gear, the mixer can also be operated at different heights..
The material of the guide rail system depends on the sewage constituents, such as the chloride
content. Wilo can process and deliver the materials common in water treatment system construction: A2-steel (AISI 304/1.4301) and A4-steel (AISI 316TI/1.4571). Standard lengths up to
19.7 ft (6 m) are available. Custom lengths available on request
Installation is complete without welding work. The guide rail system is installed using buildingapproved anchor bolts directly on the structure. In the case of fixation to steel construction
parts, installation is done using rust-proof screwed connections.
AVM guide rail system... for Uniprop, Maxiprop and Megaprop submersible mixers
The guide rail systems of type AVM… are fixed tripod systems for free installation in basins.
With these, mixers can be placed for optimum mixing results. The guide rail system absorbs
the mixing forces which arise and transfer them to the structure. A high resisting torque in the
guidetubes, plastic linings in the sliding carriage and large-area rubberised supports guarantee
high mounting security and long service life.
If the guide rail system is mounted to a concrete slab, this can be installed later in an already
filled basin.
AVR guide rail system... for Rezijet recirculation pumps
The guide rail systems of type AVR… are fixed tripod systems for wall mounting. Re-circulation
pumps can be directly flanged on the discharge pipe using these.. Due to the different variants
of the guide rail system, installations are also possible on the basin walls.

Submersible mixers
Auxiliary hoisting gear 275 lbs (125 kg) to 771 lbs (350 kg)
By using an auxiliary hoisting gear, the submersible mixers or recirculation pumps can be easily
installed or hoisted from the basin for maintenance purposes at any point of time. The auxiliary
hoisting gear consists of a holding sleeve and the actual auxiliary hoisting gear. This is why one
auxiliary hoisting gear can be used for several units. The holding sleeve can be mounted on the
ground or laterally on the wall.
For Miniprop and smaller Uniprop submersible mixers, the hoisting gear can be used to operate
the unit at different heights.
The auxiliary hoisting gear as well as the holding sleeves are produced in galvanised steel, A2steel (AISI 304/1.4301) and A4-steel (AISI 316TI/1.4571) and have a max. bearing capacity of
275 lbs (125 kg), 551 lbs (250 kg), 661 lbs (300 kg) or 771 lbs (350 kg). The rope pulley and
the sliding elements in the holding sleeve are of sewage-resistant plastic. The hoisting gears
can be equipped with a hand winch in aluminum or stainless steel. This is adjutable to any
heights from the 551 lbs (250 kg) version onwards.
All auxiliary hoisting gears have been tested and certified by the LGA and have the GS quality
mark.
Auxiliary hoisting gear Z, ZT1 and ZT2
By using an auxiliary hoisting gear, the submersible mixers or recirculation pumps can be easily
installed or hoisted from the basin for maintenance purposes at any point of time. The auxiliary
hoisting gear consists of a holding sleeve, a supporting tube and up to three booms (Z, ZT1,
ZT2). By using several holding sleeves, auxiliary hoisting gear can be used for several units. The
holding sleeve can be mounted on the ground or laterally on the wall.
Accessories
The auxiliary hoisting gear as well as the holding sleeves are made of A2 steel (AISI 304/
1.4301) and have a max. bearing capacity between 1102 lbs (500 k)g with a jib length of 5.2 ft
(1.6 m) to 551 lbs (250 kg) with a jib length of 10.5 ft (3.2 m). The rope pulley and the sliding
elements in the holding sleeve are of sewage-resistant plastic. The hoisting gears can be
equipped with a hand winch in aluminum or stainless steel. This is continuously height-adjustable.
All auxiliary hoisting gears have been tested and certified by the LGA and have the GS quality
mark.
Additional cable anchoring
In most cases, the power lines are fastened to the traction cable and are installed upwards
At high flow rates, very strong traction forces act on the traction cable and on the power lines.
To relieve both, additional rope anchoring made of polyamide can be used.The traction forces
are then absorbed by the polyamide rope.
Furthermore, rope anchoring is recommended when using a catch hook or catch device, since
here the traction cable does not remain in the basin.

Accessories
Submersible mixers
Special fixation components
When using auxiliary hoisting gear for several units, the traction cable must be removed after
lowering from the auxiliary hoisting gear.
In order to securely fasten the traction cable, we recommend the use of a rope fixation.This is
mounted on the edge of the basin near the holding sleeve.Here, the traction cable can be
wound up and fastened with a rope clamp.
Catch hook
When the units are installed, the traction cable usually stays in the fluid. Here, it is subject to
considerable traction forces, however, and is therefore subject to a high amount of wear.
When a catch hook is used, the unit can be lowered as usual. Once the unit has been lowered
onto the support, the catch hook is released and can be pulled out of the fluid again. This way,
the traction cable is not subject to the fluid.
The catch hook is suitable for use in shallow depths up to max. 9.8 ft (3 m).
The combination catch hook and auxiliary hoisting gear is especially a good choice when auxiliary hoisting gear is to be used for several units. Then one doesn't have to remove the traction
cable from the auxiliary hoisting gear and doesn't require any more equipment for securing the
traction cable.
Catch device with guide element
When the units are installed, the traction cable usually stays in the fluid. Here, it is subject to
considerable traction forces, however, and is therefore subject to a high amount of wear.
When using the catch device with a guide element, the unit can be lowered as usual.Once the
unit has been lowered onto the support, the catch device is released and can be pulled out of
the fluid again.This way, the traction cable is not subject to the fluid.
The catch device with guide element is a further development of the normal catch hook.If one
has to know exactly where the catch clip is with this one, a guide element is used.This is simply
stuck onto the guide tube of the guide rail system and lowered on this.Thus, lifting the units is
also no problem, since the catch device automatically engages in the catch clip.
The catch device is suitable for use from 6.6 ft (2 m) depth onwards.
The combination catch device with guide element and auxiliary lifting gear is especially a good
choice when auxiliary hoisting gear is to be used for several units.Then one doesn't have to remove the traction cable from the auxiliary hoisting gear and doesn't require any more equipment for securing the traction cable.

Custom-made accessories upon customer request
Since Wilo manufactures its accessories completely in-house, it is possible to accommodate
special customer wishes. For example, guide rail systems can also be made for depths deeper
than 19.7 ft (6 m).
Furthermore, special versions can also be made for special customer requirements. For example, a special guide rail system was designed for a wastewater treatment system.. This guide
rail system had to be fastened to a concrete bridge and the mixers had to be installed while the
system was in operation.
For another wastwater treatment system, a mixer was installed in a floating raft. This way, it
was possible to optimally position the mixer for different requirements. The raft was stabilized
by four ropes.In order to lift the mixer out of the raft for maintenance purposes, a guide rail
system was also built into the raft.

Leakage monitoring
Leakage which comes in through the mechanical seal on the fluid side, is absorbed by the sealing chamber (Miniprop and Uniprop directly driven) or pre-chamber (Uniprop with gear, Maxiprop and Megaprop). In order to guarantee optimum control, an external sealing chamber electrode can be attached. As soon as a certain amount of water is in the sealing chamber, this can
be signalized by a lamp or the unit can be switched off. The external sealing chamber electrode
can be retrofitted on all units.

Jet cleaner and Aerator
Cleaning stormwater overflow basins
Technical equipment Jet cleaner and Aerator Subject to change without prior notice 12/2010 WILO SE Wilo Catalog Sewage treatment - Submersible mixers - 60 Hz
In combined sewer systems, storm overflow basins are placed upstream of the wastewater treatment plant. They provide flow equalization between the sewer system and the wastewater plant. In the
event of a large storm, these overflow basins provide hydraulic detention for the storm water and allow the system to maintain effective treatment throughout the storm. After the rain subsides, the
water contained in these basins can be gradually released back into
the system to be treated.
The Wilo jet cleaner operates according to the venturi principle where
air is pulled in via the air suction pipe and mixed with the storm water
in the jet pipe. The air/water jet is expelled under pressure mixing and
suspending the contents of the basin.
The combined sewage that is generated during a storm can provide a
scouring effect in the collection system washing the solids into the
storm overflow basins. Due to the low velocity of the draining cycle,
these organic solids can settle out and remain in the overflow basin
after the storm event. These solids will begin to decay in the now dry
basin which can result in strong, unpleasant odors.
In order to keep the basins operational and free from odors, a number
of solutions have been developed -- mechanical evacuation, high
pressure wash down and conventional jet aeration devices. These
basin cleaning solutions, some of which are very complex, share one
common flaw -- they are only put into operation after the storm
event when the basin is empty.
None of these solutions provided satisfactory cleaning results. The
wastewater system personnel still have to clean the basin by hand,
which is very time consuming.
Function of the jet cleaner
Due to the jet cleaner, a type of cleaning has been developed for rain
basins which combines several advantages. The jet cleaner is put into
operation already during the start of draining the rain spillway basin.
It suspends the solids and dirt particles. These leave the basin together with the water.
The Wilo jet cleaner consists of a Wilo submersible sewage pump
with injector, air suction pipe and jet pipe. The jet cleaner can be installed in nearly any new basin and can be retrofitted in existing basins.
Advantages of the jet cleaner
In the Wilo system, the basin is sloped downward approximately 23% toward the drainage channel which creates a return flow during
the circulation process. During the process, organic and inorganic
substances are mixed and conveyed to the drainage channel. Additionally, the Wilo jet cleaner enriches the water with oxygen to prevent septicity.
That means:
• No odor emission due to escaping gases.
• No contamination of the wastewater treatment system by foul water,
which saves energy when cleaning the sewage water.
• Elimination of a hazard of the downstream channels due to hydrogen
sulfide.
• Prevention of the development of sewer slime.
• No use of external water for the cleaning process. Storm water is
used.
• The cleaning process already begins when the basin is drained and
Technical equipment
continues until the basin is drained completely.
• The dirt particles are distributed almost evenly to the out-flowing
basin water.
• The wastewater treatment system is not subject to a flow surge.
• The basin walls are scoured clean.
• The storm water is constantly enriched with oxygen. As a result, there
is no formation of hydrogen sulfide and no unpleasant odors.
• Comminution and dissolving of organic coarser solids.
• Low investment and maintenance costs, and longer service life of the
equipment.
• Overall reduced operating costs due to efficient operation and fully
automatic operating sequence.
Basin design
For using the jet cleaner as a cleaning device, the following design
features should be observed when planning a storm water overflow
basin:
The Wilo submersible sewage pump pulls the rainwater out of the
drain channel and pumps it through the injector nozzle via the jet
pipe and back into the basin.
Rectangular basin
• The ideal relationship between width and length is 1:2
137
Technical equipment
Jet cleaner and Aerator
• The bottom of the basin should be horizontal without any transverse
inclination, but designed with a longitudinal inclination of 2-3 % to
the drainage channel.
• The volume of the drainage channel is to be adapted to the basin size
and should include a useable volume of at least 3 % of the basin area;
the drainage channel is for taking the inorganic solids and as a water
reservoir for the remaining cleaning of the bottom of the basin. The
inclination in the channel should be as steep as possible towards the
outlet flap or to the drainage sump (5 %).
• The basin should be drained as quickly as possible. While this is assured for systems using pumps, when systems drain by gravity
through a flap valve, care must be taken to locate these valves at a
height that provides sufficient pressure to ensure proper operation.
• The basin inlet is to be placed on the side of the outlet channel. If
there are minor deposits in the channel from the last cleaning operation, they are rinsed off during the aeration process.
• The jet cleaner is installed on the bottom of the basin directly next to
the drainage channel.
Round basin
• In the case of the round basin, the bottom is to have a horizontal de-
• The round basin should also have a rinsing channel.
• The other design features of the rectangular basin are to be applied.
Technical data with design criteria
When selecting the jet cleaner, observe that the energy density
should be 17-23 ft lbf/s per yd3 (30-40 W/m3 ) (in relation to 30 % of
the basin's volume).
The motors are also available in Ex design. Fastening mechanism and
jet pipe are made of hot-dip galvanised steel or stainless steel.
Control and switching systems
The operation of the Wilo cleaner is automatic. The cleaning system
operates either intermittently or continuously in response to the level
in the storm overflow basin.
In the control system, all sensors, control elements and all motor
control equipment are included. Level sensors are of the bubbler, ultrasonic or submersible transducer type.

Grit collector pumps
A grit chamber is a sedimentation tank for removing coarse, settleable contaminants from the sewage, such as sand, stones or bits of
broken glass. These substances would easily lead to operational malfunctions in the wastewater treatment system (wear, clogging).
Technical equipment Grit collector pumps Subject to change without prior notice 12/2010 WILO SE Wilo Catalog Sewage treatment - Submersible mixers - 60 Hz
Pumpling out the grit chamber therefore poses extreme demands in
terms of the wear resistance of the pump. Furthermore, solidified
sand deposits must be resuspended in order to be pumped and the
unit must be frost- and weather-proof.
Therefore, sewage pumps are used increasingly in grit removal systems. For this area of application, Wilo offers its proven submersible
sewage pumps of the type: Wilo-EMU FA…WR. The submersible sewage pumps are submersible and can be directly submerged in the fluid. Thus, no suction piping is required and the pumping system is
completely submerged with no exposed machinery.
For this application, the Wilo submersible sewage pump is equipped
with a vortex impeller and a mechanical mixing device. The mixing
device is screwed directly onto the impeller. It consists of a smooth
pipe cylinder and a mixer head, which is ground to an s-shape on the
front surface.
Only the grit that is in the area of the pump suction is resuspended to
maintain the effectiveness of the grit removal system. Solid deposits
are loosened up and can be pumped. Due to the narrowly limited flow
zone, the settling of sand is not disturbed. The smooth pipe cylinder
can usually flush long fibrous substances away on its own. Since the
mixer head is subject to a high amount of wear, it is constructed of
the martensitic-structured chilled cast iron material Abrasit.
The combination of suitable wear-proof materials and coatings ensures long-term and trouble-free operation.
