Get rid of 100% of your bacterial threat with a non toxic and really green product, conform with sustainable development

Amoéba's Green biocide (BIOMEBA) is appropriate for use in cooling towers (TP11) and will be commercialised in conditioning compatible with this application. In line with European CLP regulations, the material safety data sheet carries no indication of hazards.

No modification to your installation is necessary, dosing is performed using a dosing pump which adds the product either through a secondary water supply conduit, or directly to the cooling tower.

Amoéba's biocide can be used in all cooling systems regardless of their volume. As the product is classed as without hazards for humans or the environment, no modifications of the biocide storage area are necessary, providing that you dispose of a retention tray.

Using our product also makes it possible to diminish strongly the use of corrosion inhibitors and to stop completly the use of biodispersants.

Small volumes of Amoéba's biological biocide can be used: 1 litre @ 3% treats 10 m3 of water; 1 litre @ 30% treats 100 m3.

True substitution technology for oxidising and non oxidising chemical biocides, Amoéba's biological biocide also helps to preserve your installations and make it last about 12% longer.

BIOMEBA R&D Test Process

Tests on industrial sites with BIOMEBA biological biocide (under the name GREEN BIOCIDE in France) are being carried out for research and development purposes.  

These tests take place on a minimum 5 months basis and in 2 different phases:

  • Phase 1: one-month chemical treatment pre-test phase. Carried out with the already used chemical biocide treatment to obtain indicators determining the network benchmark, making it possible to carry out a comparative technical, economic and financial assessment, at the end of tests.  
  • Phase 2: biological treatment test phase, lasting at least 3 months. Carried out with BIOMEBA biological biocide treatment to demonstrate and prove the treatment’s effectiveness when it comes to managing the risk from proliferation of Legionella pneumophila.

The use of BIOMEBA biological biocide makes it possible to do away with chemical biocide treatments (all of which are toxic and can be corrosive) and allows a general reduction in dosage of anti-corrosion products that are made necessary by the intensive use of oxidizing chemical biocides. Its use also allows a significant reduction in the amount of product required for the treatment of air-cooled towers (ACT) and makes it possible to completely eliminate bio-dispersants. However, anti-scale protection programs remain unchanged.

8 years of cumulative tests have been carried out on different volume circuits, on open and semi-open circuits. They have always shown superior effectiveness of BIOMEBA biological biocide against Legionella compared with chemical biocides. Comparative analyses and data collection also show more favourable economic and financial results of BIOMEBA use.

Users greatly appreciate indirect benefits of BIOMEBA, such as storage space savings and ease of implementation. BIOMEBA has been categorised as “without class of hazard to human health and the environment”, which offers an additional advantage in terms of safety of employees and environmental protection.
