Method of Decontaminating Waste Liquors

摘要

Contaminants are removed from waste liquor particularly in a closed recirculatory system by adding a soluble silicate to the contaminated waste liquor in an amount sufficient to flocculate the contaminants. Then, the liquid is treated to separate the flocculated contaminants therefrom. Other features for enhancing flocculation of the contaminants in a waste liquor in conjunction with the above method are described. The method of the invention has particular application to wool scouring liquor.
