Hydrolysis of polyaluminum chloride prior to coagulation：Effects on coagulation behavior and implications for improving coagulation performance

The effects of polyaluminum chloride（PACl） hydrolysis prior to coagulation on both the coagulation zone and coagulation performance of a kaolin suspension were investigated by a novel jar test named the ＂reversed coagulation test＂.The tests showed that PACl hydrolysis prior to coagulation decreased...
