PREPARATION OF HIGH EFFICIENT COAGULANT OF POLYSILICATE ALUMINUM FROM POOR QUALITY KAOLIN

A new preparation method of high efficient coagulant of polysilicate aluminum (PSA) from poor quality kaolin was studied in this paper,determining the reasonable production craft and operating conditions.The coagulant was tested in industrial wastewater treatment and compared with traditional coagulant.The experimental results show that PSA has better coagulation property than the traditional coagulant,and the dosage of PSA is less.
