Procedure and installation of treatment of liquid effluents containing especially pollutants in suspension.

摘要

Method for cleaning and filtration of fluids, especially liquid effluents such as raw water containing organic pollutants in solution and using means of gravity, such as especially a decanter and a float separation and membrane separation means as step finishing, according to which a coagulant is injected at a point of the supply conduit raw water and pulverulent reactant is introduced upstream of the membrane member separation recycled this pulverulent reactant from the membrane separation means toward the side water above the gravity separation means, this method being characterized: in that a first powdery reagent is introduced downstream of the injection point of the coagulant and upstream of the gravity separation, because this first powdery reagent and the second powdery reagent that water is introduced above the separation n membrane member, different presentancaracterísticas, especially particle size and adsorptivity suitable for the pollutants to be eliminated, and because the time of the first powdery reagent in its contact reactor is between 5 and 60 hours.
