Abstract
PURPOSE: To flocculate a suspension contg. sulfate ions efficiently by adding alkaline earth metallic compounds and a cationic flocculating agent to said suspension.
CONSTITUTION: Alkaline earth metallic compounds are added to a suspension contg. sulfate ions prior to addition of a cationic flocculating agent, and after these are agitated, said flocculating agent is added or the alkaline earth metallic compounds are added simultaneously with said flocculating agent under agitation, whereby flocculation is accomplished. Said alkaline earth metallic compounds are salts and hydroxides, except sulfate, or calcium, magnesium and barium, and there are chloride, nitrate, etc. as the salts. The above-described flocculating agent is added by a method of adding the same usually as an aq. soln. of 0.05W0.5wt%. The alkaline earth metallic compounds are added as an aq. soln. or suspension.
