using polyaluminium coagulants in water treatment

USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT

2.0 POLYALUMINIUM COAGULANTS. Recently, a number of alternative aluminium-based coagulants have been developed for water treatment applications. These compounds have the general formula (Aln(OH)mCl(3n-m))x and have a polymeric structure, totally soluble in water. The length of the polymerised chain, molecular weight and number of ionic charges ...
