Method for cleaning a filtration installation of the type with immersed

This invention relates to a plant for the biological treatment of water to produce drinking water, characterized in that it comprises at least one biological reactor (7) provided with injection means (9) for injecting oxygenated gas, at least one separation membrane (11 for microfiltration or ultrafiltration immersed in said reactor (7), and addition means (10) for adding to said reactor (7) at least one pulverulent material in suspension serving as a support for a biomass, said pulverulent material possibly being a reactive powder which also allows fixation of the substrate required by said biomass.

Installation for biological water treatment for the production of

A water-treatment installation, notably with a view to making water potable, includes a reactor demarcating at least one treatment chamber, the reactor comprising a conveying assembly to convey the water to be treated into the chamber; a removing assembly for removing the floated pollutants and a removing assembly for removing the decanted pollutants; a plurality of filtration membranes laid out within the chamber and submerged in the water to be treated; a demarcating assembly for demarcating a filtration zone around each of the membranes; carrying and circulating member guiding a current of water to be treated in the filtration zone along a preferred direction, the carrying and circulating member including ozone-injection assembly; and a recovering assembly recovering the permeate at an outlet of the filtration membranes.
