| Abstract: | PASS flocculant was prepared. The optimum conditions of preperation are pH=5.5-6.0, the concentration of SiO2=2.0-3.0%, Al/Si (molar ratio)=0.5 or 1,0. X-ray diffraction proved that Al2(SO4)3had reacted with polysilic acid and produced the non-crystalline polymer. The experiment for application shows that the Al/Si is the most important factor that affects the floc-culation efficiency of PASS. And PASS is very efficient for the water treatment that has low turbidity and high color degree. |
