Why do we need Amoéba’s biocide?
Amoéba’s biocide effectively eliminates deadly bacteria from industrial water


Water in industrial installations is a breeding ground for bacteria including Legionella, which causes potentially fatal Legionnaires disease1. Other potentially fatal diseases are caused by pathogenic bacteria such as Klebsiella2, Pseudomonas3, Chlamidia4. Chemical water treatments - chlorine/bromine, isothiazolone - available since 1914 and 1974, respectively, have a very low efficacy. However, until now they were the only solution to the threat. These chemicals are used daily, in large quantities, to produce imperfect results, even though they are toxic for humans and the environment.

Amoéba’s biocide is the first 100% effective solution against waterborne bacteria, as well as being harmless to humans and the environment. This is a true breakthrough, a revolution.

What is a biocide?
A biocide is a disinfectant that kills dangerous micro-organisms and parasites

Bacteria, viruses and parasites can be dangerous to living creatures. Biocides - literally “killers of life” - have thus been developed for medical, veterinary, domestic and industrial applications, to disinfect water, air, floor surfaces, swimming pools, work surfaces, toilets, etc. Most biocides are chemicals, many of which are toxic. Because of this, their use is monitored. In Europe, specific regulations have been developed for biocidal products.

Amoéba’s biocide is NON-chemical. It is the natural - i.e., not genetically modified - amoeba Willaertia magna C2c Maky. Our biological biocide has passed all the tests required for biocides in Europe. The conclusion of these tests was that our product presents no danger to humans or the environment.

Does Amoéba’s biocide help to protect human health?
Yes, in two different ways!

Amoéba’s biocide is designed to eliminate various micro-organisms present in the water used in industry, some of which are deadly (see Why do we need Amoéba’s solution?). The tests carried out in several industrial setups showed that this product is really effective. So, yes, Amoéba’s biocide does help to protect human health. In addition, in the occupational setting, exposure to Amoéba’s biocide, unlike the chemical biocides currently used, presents no risks as it has been shown to be completely safe for humans.

Is Amoéba’s biocide dangerous for the environment?
No. Amoéba’s biocide conforms to the European regulations and North-American recommendations.

Firstly, all tests show that our biocide is not present at the outlet of the industrial water circuit. In addition, all the required European regulatory tests to determine the hazards represented by biocides concluded that there was a total absence of ecotoxicity. Finally, Amoéba’s biocide, the amoeba Willaertia magna C2c Maky, is a relatively fragile organism, which cannot survive in natural water courses or water treatment stations. Thus, Amoéba’s biocide complies fully with the requirements of the 2015 European framework directive, aiming to reduce pollution in waterways, and with the current recommendations for sustainable development in Canada and the USA.

Is Amoéba’s biocide economically advantageous?

Amoéba’s biocide makes long- and short-term savings possible, in several complementary ways, while also being easy to integrate into current procedures:

- Firstly, as Amoéba’s biocide is not corrosive to the structures where it is used, it increases their longevity. It is therefore a source of savings in terms of structural investments (corrosion is reduced by 12.5%).
- In addition, water consumption is reduced by 10%.
- Storage of the biological biocide is unnecessary, freeing up considerable space and reducing the need for complex logistics.
- Personnel do not need to wear protective equipment.
- Finally, but very importantly, using Amoéba’s biocide allows European users to comply with European directive 2000 / CE / 60 and thus avoids the need for companies to pay fines and eliminates the related administrative problems. In North America, Amoéba’s biocide also complies with the recommendations and helps its clients to adopt recognised sustainable development approaches.

Where can Amoéba’s biocide be used?
In ACT and soon in the construction sector

Amoéba’s biocide meets the needs of a range of sectors, by we are currently focusing on developing and marketing for industrial applications, in particular for air-cooled towers, ACT (TP11), also known as cooling towers.

What is the potential turnover for Amoéba’s biocide?
The potential turnover for ACT alone is 1.7 bn€/year

In a worldwide market of chemical biocides estimated to be worth 21 bn€, AMOEBA is today concentrating on the industrial air-cooled towers (ACT) segment estimated to be worth 1.7 bn€.

How effective is Amoéba’s biocide?
Amoéba’s biocide is almost 100% effective

This is the only biocide available, e.g. for use in air-cooled towers, to present almost 100% efficacy. How do we know? Based on samples taken at the outlet from ACT. The unparalleled efficacy of Amoéba’s biocide can be explained, among other things, by the fact that it not only eliminates micro-organisms from the water, but also from biofilms, the sticky layer that builds up inside pipes and is used as a hiding place by dangerous bacteria. Our final users – Häagen Dazs , Vitacuire and Arcelor-Mittal – confirm this efficacy with conviction.

Is Amoéba’s biocide an innovation on the biocides market?
Yes, Amoéba’s biocide is a unique technology, and it has been patented.

Amoéba’s biocide is arriving on a market worth 21 billion € per year, where only chemical biocides are available. The last innovation on this market was made in 1974 with the introduction of isothiazolone. Amoéba’s biocide is a real, natural, disruptive technology, there is no competition and the product is strongly protected. The administration has recognised that the biological biocide does not require hazard classification for human or environmental hazards. Amoéba thus offers a true innovation on an established market while distinguishing itself from the competition in terms of performance and through its ecologically responsible characteristics. Amoéba’s natural biocide is, today, THE most effective solution on the market, almost 100% effective in eliminating bacteria.

Can Amoéba’s biocide replace chemical biocides?
Yes, Amoéba’s biocide is a true substitute solution!

Amoéba’s biocide was designed to be used without requiring major changes to industrial setups, or to other products used in industrial procedures. It is therefore a true substitute solution, and the switch from chemical disinfection of water circuits to Amoéba’s solution can be done rapidly. Your water treater will only need 1 day to make the only change necessary, which consists in installing a pump to inject the biocide into the circuit. The installation can be viewed in the testimonial films recorded on the sites of our final users Häagen-Dazs and Arcelor-Mittal.

Water and industry: the essentials

In industry, water is used to reduce temperatures for various procedures

Because of its properties, water has become essential in most industrial production and transformation processes.  It is used to eliminate the heat produced by production machines or to maintain controlled temperature conditions for the components contained within these machines, for various production phases and in different work areas. Examples: to cool molten metal, for high-temperature ovens in food and agriculture, for air-conditioning. These applications consume 20% of all drinking water.

Air-cooled tower, ACT: cool water using air

An air-cooled tower (cooling tower) is used to cool water through contact with outside air. In technical terms, this is known as an air/water heat exchanger. Hot water, sprayed in the upper part of the ACT, runs over a heat exchange part through which air circulates. The cooling is mainly effected by evaporation of the water. This creates water-saturated air, visible as a cloud. This cloud, known as a plume, contains steam and fine droplets of water from the cooling circuit. 

The ACT can be a source of bacterial contamination, and it is therefore necessary to clean the water.

The water droplets present in the cloud released by the ACT can transport bacteria which develop in water circuits: Legionella, Listeria, Salmonella, etc. To reduce the risk of contamination, the water arriving in the ACT has to be cleaned upstream. Further details can be found on the Ministry of ecology and sustainable development’s website.

Industrial requirements in terms of emissions from ACT

To protect the environment, the public authorities are acting to limit the hazards related to chemicals used to eliminate dangerous bacteria from water in industrial installations.
The 2015 European framework Directive was launched in 2000. This directive prohibits the emission of chemicals in water and requires industries to re-treat waste-water or adopt cleaner solutions.
On the American continent, Canada and the USA have also developed measures to promote sustainable development.
