Study on Application of Polymeric Aluminum Magnesian Silicate-sulfate

Xingang Wang, Ren Zhao-hua

Abstract

It was studied and analyzed that the wastewater was treated with new flocculant polymeric aluminum magnesian silicate-sulfate (PAMSS)by the method of orthogonal test, and the factors concerned to influence the flocculent performance were discussed. Through the experiment, it is thought that as the molar ratio of among Mg, Al and Si is 1.0∶1.0∶1, the dosing quantity is about 100 mg/L, the pH value of water to be treated is from 6.5 to 7.5, and the stirred time is from 10 minutes to 13, the removals of COD(Cr)and turbidity can reach 82.85% and 91.98% respectively, which excel both polymeric aluminum sulfate (PAS) and polymeric aluminum silicate-sulfate (PASS) in the flocculent performance.
