CYCLIC ACTIVATED SLUDGE TECHNOLOGY
SFC is a specialised company for process
technologies in the field of water and
wastewater treatment.
Typical clients are municipalities, industrial
The C-Tech
TM
process is a cyclic activated sludge process,
whereby carbon oxidation, nitrification, denitrification and
bio-P removal are carried out simultaneously.
The process control based on online respirometry allows the
omittance of equalization tanks, mixing devices and shock filling,
as in SBR- systems usually required. A continuous treatment is
achieved by installing two or more parallel operating basins.

C-TECHTM Beijing
TM
C-Tech basins can be manufactured in round or square shape.
The following devices are part of the process:
3 selector for simultaneous N/DN, bio-P removal
and control of bulking sludge
3 highrate decant arm with scumguard to remove
treated effluent
3 sludge recirculation pumps into the selector compartments
3 control system via OUR
3 fine bubble aeration system
clients, general contractors and real estate
companies.
Main business activities are consulting and
design and supply of equipment, EPC and
turn-key contracting.
Process advantages
3 less area and volume requirement
3 less M+E equipment
3 highest elimination rate for N and P
3 suppression of filamentous organisms
3 highest flexibility against dynamic flows and
loading at reduced operation costs
The system has been implemented in various reference plants
in all continents and is currently featuring the worldwide
largest facility of its kind for up to 600,000 m3/d.
Simultaneous nutrient removal
The relatively short cycle of approx. 2-4 hrs in combination
with the selector and the process control allows for simultaneous N/DN.
Nitrification takes place at the periphery of the floc, whereas
denitrification occurs within the floc.
The control system computes the required aeration time and
rate, which allows effluent concentrations of BOD/SS/TN/
TP < 10/10/10/1mg/l
P-release takes place in the selector, P-uptake in the aeration
zone.

Continuous operation
The installation of parallel basins allows a continuous plant
operation with continuous influent and discharge. Through
the PLC system each individual basin can be taken out of
service for maintenance purposes without affecting the
continuity of the process operation.
Cycle
Within one cycle the phases aeration, settling and decanting
are repeated continuously. Thus, all necessary reaction conditions for simultaneous nutrient removal and sludge settling
are completed.
The phase delay between the basins leads to a continuous
process wherein all installed machinery and aggregates are
most efficiently used.
Options
The process and cycle design can be adapted to:
3 nutrient removal
3 C-removal only
3 simultaneous sludge stabilization
3 nitrification at very low temperatures
3 enhanced bio-P
3 with or without primary settling tanks
3 with or without anaerobic digestor
Applications:
3 Sewage treatment
3 Beverage and food industry
3 Paper industry
3 Pharma and chemical industries
3 Petrochemical industries
3 Textile mills
3 Large scale and containers
3 Overground and underground
