摘要: The invention concerns a flocculation-decantation method by ballasted flocs using granular material and step which consists in treating the sludge derived from circular grit trap wherein auxiliary liquids tangentially injected into substantially same direction as latter. also with cylindrical part of diameter D supplied suspension to be treated conical provided chamber injecting wash-water at outlet having D′ ranging between 0.35 0.65 D, said least tangential supply liquid along feeding treated.
