Wastewater as a source of income – Trends-Tendances sur PC

The Belgian SME Anatis, an industrial contractor based in Liège, has developed a patented system for treating effluents which makes it possible to transform purification costs into a source of development.

Natural, automatic and patented. Another Walloon pride in the head of Anatis, founded in 2012. The company specializing in the study and construction of industrial installations has developed a system for the treatment and recovery of liquid industrial waste. A solution for an umpteenth major ecological, social and economic challenge that is wastewater treatment. Effluent discharge standards are becoming more and more restrictive. To the point of penalizing production and weakening development prospects in sectors such as the food industry.

Natural, automatic and patented. Another Walloon pride in the head of Anatis, founded in 2012. The company specializing in the study and construction of industrial installations has developed a system for the treatment and recovery of liquid industrial waste. A solution for an umpteenth major ecological, social and economic challenge that is wastewater treatment. Effluent discharge standards are becoming more and more restrictive. To the point of penalizing production and weakening development prospects in sectors such as the food industry. “We are seeing in the field that more and more of these manufacturers are facing treatment costs that are becoming excessive, saturation of their wastewater treatment plant or even difficulties in renewing their operating permit, observes Raphaël Anciaux, administrator of Anatis.” Anatis claims an alternative to conventional water treatment which reduces pollution by up to 90%. Its proprietary system that it markets, Fluid-Anyole, operates according to a bio-methanation process adapted to agricultural and agro-food effluents. Without sinking into technical complexity, bacteria digest the organic matter present in the liquids discharged and transform it into gas. This gas is then recovered, making the system energy self-sufficient (possibly with a surplus of energy from which the company can benefit). “You have to see our system as a Club Med for bacteria. By maintaining them in optimal conditions and configurations, bacteria help reduce the organic load, the main source of pollution in agri-food wastewater”, explains Thomas Reynders, director of operations at Anatis. In order to design a reliable system as required by the industrial sector, the Walloon company has forged technological and strategic partnerships with renowned players in the country, such as Cebedeau, a water treatment research center, Henkens Frères for the on-site industrial installation or Van Wingen for the cogeneration engines. With its Fluid-Anyole, Anatis supports industrial SMEs in a logic of circular economy by reversing the financial steam, transforming increasing treatment costs into a regular “green and profitable” investment. In any case, this is the demonstration that the Liège company retains from its first installation carried out within the famous brewery-cheese factory in Orval. “The reduction in pollution of the water sent to the existing wastewater treatment plant makes it possible to consume half the energy. Added to this are the investment aids from the Walloon Region as well as the green certificates for electricity produced by biogas”, we welcome at Anatis. This new process also allowed the Trappists to internalize the treatment of waste (whey from the cheese dairy and yeast from the brewery) which had previously been treated and then evacuated by truck. It is therefore a sustainable investment since it greatly reduces their energy balance. FRANCOIS REMY
