Removal of phosphorous from waste water |
| abstract |
Phosphate is removed from an aqueous medium by adding inorganic coagulant followed by a cationic polyelectrolyte which is a water-soluble quaternary ammonium salt of a high molecular weight copolymer of acrylamide and an alkylaminoalkyl ester of acrylic or methacrylic acid. The process is of particular value in reducing the phosphate content of sewage effluent. |
