PROCESS FOR FLOCCULATING SUSPENSIONS

摘要

A process of flocculating and dewatering an aqueous suspension of suspended solids comprising, introducing into the suspenison, (a) polymer composition of between 40% and 60% by weight and, (b) polymer composition of between 0.05 to 0.2% by weight, characterised in that the polymer compositions are introduced into the substrate substantially simultaneously. The process brings about improvements in filtration and cake solids.
