Abstract (en)
[origin: WO2022091036A1] A waste water treatment method includes the steps of supplying a volume of waste water within a clariflocculation tank (3), first release of a first inorganic mineral containing zeolites within the tank, stirring the volume of waste water in order to spread the first inorganic mineral within the volume of water, second release of a second inorganic mineral containing bentonite within the tank (3) and interruption of the stirring to promote the flocculation of the bentonite and allow the separation of the volume of waste water into a first fraction (W) of purified water and a second fraction (M) of sludge.
