Effect of Flocculation on Gypsum Filtration Efficiency

Improvement in filtration efficiency of gypsum upon flocculation is determined to be due to reduction in the blockage of filter media pores and in the filter cake resistance. An optimum in polymer dosage is explained in terms of stabilization of fines and deformability of the flocs formed. Anionic polyacrylamides were found to be more effective filter aids than cationic polymers.
