Better than chemical solutions. Why?
3.1
BIOMEBA is in accordance with Water Framework 3.7
Directive.
The European Water Framework Directive imposes the
reduction of discharge of certain dangerous substances
into the environment. BIOMEBA meets this requirement
and thus allows a reduction in environmental taxes.
3.2
Greater

3.8
alternatives.
8 cumulated years of tests carried out in industrial
environments so far have shown that BIOMEBA is
effective both in the water phase and on biofilms.
3.3
Control of biological growth in circuits.
Total flora is under control: it gets stabilised after the
beginning of treatment with BIOMEBA and decreases 3.9
over time. Unlike with chemical biocides, there is no
inhibition of microbial flora reading.
The installation lasts longer.
Unlike oxidizing chemical biocides, BIOMEBA does not
cause corrosion in installations. Tests carried out on an
industrial scale have proven the possibility of a
considerable reduction in the consumption of
anti-corrosion products. The reduction varies between
5 and 25%, depending on the installation.
Reduced need for blow-down, leading to water
savings and cost reduction.
With BIOMEBA there is no mineralization of water,
unlike with chlorine, bromine, etc. Therefore, it is
possible to increase circuit concentration and to reduce
water consumption.
Reduced transportation costs and optimized carbon
footprint.
With BIOMEBA, the lower volumes of biocide necessary
to treat water circuits considerably reduce the amounts
of product to be transported, making it possible to
reduce supply volumes and related costs.
3.4
Elimination of multi-product programs combining
oxidizing biocides, non-oxidizing biocides and
biodispersants.
The efficacy of BIOMEBA's program has been proven by 3.10 Storage area reduced and made secure in

has been demonstrated at the level of biofilms that are
the main source of contamination.
3.6
10 to 100 times lower volumes of biocide are
necessary, depending on the dosing program.
The stability of BIOMEBA over a broad pH range makes
it possible to reduce biocide consumption by 10- to
100-fold compared to the volume of oxidizing
chemical biocides.
Additional benefits
4.1
4.2
Carton packaging 100% recyclable.
Unlike with chemical packaging, BIOMEBA's container
does not require specific storage or recycling
conditions, since it is a biological product. BIOMEBA
thus eliminates additional costs related to the 4.3
treatment of chemical biocide containers.
Easy to handle cardboard packaging.
Thanks to its 10- and 20-liter packaging, the biocide is
simple to handle.
Installation: setting up a simple dosing cabinet.
The setting up of AMOEBA program requires only that a
cabinet with a dosing pump be installed by the distributor.

1.3
Amoeba’s product, BIOMEBA, is a non-genetically
modified amoeba.
BIOMEBA is Willaertia magna C2c Maky, an amoeba in
natural state that was isolated from a thermal centre.
Numerous scientific publications have shown that this
amoeba is ubiquitous in water and found at depths of
up to 50 cm in the soil.
A natural predator of Legionella, pathogenic
bacteria and free-living amoebas.
8 cumulated years of application in industrial
environments have shown the product to be effective
against multiple species of Legionella, free-living
amoebas and a large number of pathogenic bacteria
commonly fozzund in air-cooled circuits, in particular
Pseudomonas, Listeria, Klebsiella, etc.
Effective in water phase and on biofilms.
The product is active on biofilms and in the water
phase. The amoeba contained in BIOMEBA is a
natural predator which, unlike chemical biocides, is
also effective on bacteria contained in biofilm, thus
minimising the risk of proliferation of pathogenic
bacteria at the source.

1.4 Ensures that Legionella pneumophila level is low, both
in water phase and in biofilms.
The analysis can be carried out either by culture or by qPCR,
the method of quantifying Legionella pneumophila DNA found
in water. These measurements are precise and specific.
1.5 Operating conditions: Temperatures between 12° and
52°C; pH from 5 to 10.
The biological biocide BIOMEBA is not pH-dependent. It
works perfectly within the pH range of 5 to 10, which gives
it a broader action spectrum than any chemical biocide.
1.6 Compatible with commonly-used anti-scaling and
anti-corrosion products.
The tests carried out to date have shown that BIOMEBA is
compatible with commonly-used anti-scaling and
anti-corrosion products. Therefore, all systems, regardless
of the treatment currently applied, can benefit from
treatment with BIOMEBA biocide.
1.7 Product without hazard warning labels.
To date, no risk for humans or the environment has been
identified by independent studies carried out in compliance
with OECD2 and EPA3 (OCSPP4) requirements. These tests
examined the toxicology, eco-toxicology and pathogenicity of
the product.

Simple to implement
2. 1 Ready-to-use dosing cabinet for product injection.
It is easy to install; the distributor replaces the old
chemical biocide dosing system by the BIOMEBA Box.
The vessel containing the biological biocide is connected
to the dosing pump by a quick-connect system, reducing
handling time.
2.2
2.3 Multiple injection strategies: continuous or shock dosage.
The product is injected proportionately to the flow of
make-up water. Different treatment strategies can be
adopted depending on the microbiological load in the
system or other technical constraints. Continuous dosing is
added through the make-up water; shock dosing is based on
the total volume of the system.
Injected by a dosing pump.
No specific dosing equipment is required to start using
BIOMEBA. The biocide is injected into the circuit by a dosing
pump that is connected to the 10- or 20-liter packaging.
Use is simple and users do not need training.

Amoeba’s BIOMEBA does not have an authorization to be placed on the European
market yet, in accordance with the Regulation (EU) No 528/2012 of the European
Parliament and of the Council concerning biocidal products. BIOMEBA will not be
commercially available until it has been granted marketing authorization. However,
BIOMEBA has been authorized for PT11 use (Product Type 11 — preservatives for
liquid-cooling and processing systems) in some member states of the European Union
for research and development purposes in accordance with Article 56.2 of the
Regulation (EU) No 528/2012.
