, The polyaluminum chloride salt base degree than the polyferric sulfate is much higher, making the storage and transportation more difficult, if the two will produce a combination of neutralization effect, the different products of basicity changes will affect the flocculation Effect, both of them will change their basicity of the salt base will change, can not continue to hydrolysis in the sewage produce flocculation, precipitation effect, the product of alumina and iron oxide in the hydrolysis process will form a hydroxide gel, jelly shape. Thus losing the original polymerization, the production process of PAC and PFS are very different. 2, leading to imbalance of hydrolysis balance
