Our technology called FGWRS® (Full / Firmus Grey Water Recycling System) is derived from research work for the European Space Agency (ESA) carried out by FIRMUS France – our parent company. The design, implementation and monitoring of a process which has been operating since 2005 on the French-Italian Antarctic station Concordia with more than 1,200 users since commissioning without any technical or sanitary incident. The quality of FGWRS®'s produced water allowing all uses of the dwelling except drinking (1% of the daily needs). It complies with the ESA hygiene water standard.

FGWRS is developing an integrated circular economy approach. We offer to:

Recycle 80% of grey water to obtain hygienic water for toilets and the sanitary network (showers and sinks)

Achieve significant potential savings in terms of operating costs but also in the use of the resource.

Provide a simulation tool applicable to each project assessing its economic interest during the preliminary study phase.

Optimize profitability through energy recovery to contribute to the facility's thermal needs.

Work in a consortium: complementary skills to maximize the integration and valorization of the process in a building
