ANALYSIS OF BEHAVIOUR OF FLOCCULANTS-IMPROVED FILTRATION

The function of highpolymer flocculants (polyacrylamides) in filtration were investigated in a dynamicand systematic way, and the pattern of behaviour of flocculants in filtration were summarized. The functionof flocculants-improved filtration is mainly during the stage of filter cake formation and favourable to rapiddrainge of pert capillary water. but the residual moisture contents of flocculated cake are usually higher thanthose of unflocculated cake with dewatering time extended
