UNDERSTANDING POLYMER FOR THICKENING AND

Polymer is used as a flocculant for solids separation processes The aggregation of particles into larger and more easily removable forms by applying coagulants or flocculants is necessary for efficient separation by clarification decanting sedimentation filtration thickening and dewatering processes

Thickener modelling from laboratory experiments to full

Since thickeners are rate limited devices the best way to enhance throughput is via improved sedimentation For all benefits there is nearly always a trade off and in the case of flocculation it is at the expense of the potential underflow solids concentration since the addition of flocculants produces a stronger aggregate network
