Process for treating wool scouring wastes

摘要

An improved process for treating wool scouring wastes liquors in which the waste liquors are first cooled before acid and collodial bentonite are added; then the flocculated liquor is reheated to a temperature in the range of 130 DEG to 150 DEG to separate the waste liquor into a supernatent liquor and a settled drainable sludge and finally dewatering the settled sludge by centrifugal separation.
