Abstract

A process for coagulating and removing suspended matter in coal washing effluents and in water which has been chemically treated to precipitate its hardness content, comprises adding thereto a solution containing sodium alginate, and a solution containing a salt of a polyvalent metal and separating the coagulated material. Examples are given involving the use of sodium alginate in conjunction with alumino ferric sodium aluminate, or aluminium sulphate. Salts of polyvalent metals may include salts of calcium for example calcium chloride and calcium bicarbonate. The amounts of sodium alginate and salt of a polyvalent metal are generally between 2 and 30 parts and 2 and 50 parts, respectively, per million parts of liquid treated.
