摘要： The invention concerns a method for the physico-chemical treatment of water characterized in that it comprises at least a step consisting in causing the water to be treated in at least one settler providing non-thickened sludge and in at least one settler-thickener treating the sludge from the two settlers and part of the water to be treated. The invention also concerns a plant for implementing said method comprising means for supplying the water to be treated (6), at least a settler providing non-thickened sludge (2), at least a settler-thickener (5, 5a), means for conveying (7) at least part of the non-thickened sludge coming from the settler providing non-thickened sludge (2) to the settler-thickener (5, 5a), means for evacuating (9, 9a) treated water coming from said settler providing non-thickened sludge (2) and from said settler-thickener (5, 5a) and means for evacuating (8) the thickened sludge coming from said settler-thickener.
