How to judge the quality of PAC PAC good or bad?
2017-12-07 13:36:22
First of PAC PAC plays a major role in the composition of aluminum oxide, to judge the quality of products depends on the content of aluminum oxide, aluminum polychloride is generally caused by changes in the basic form of OH ions, the measure of polyaluminum chloride The index of OH ions is called the basicity of the salt. Usually, the basicity of the salt is also defined as the percentage of the amount of OH and Al in the polyaluminum chloride. Generally, the basicity of the salt should be within 40-90%. Poly aluminum chloride is highly efficient Inorganic polymer flocculant, the product is a product between AlCl3 and Al (OH) 3, the quality of PAC depends on the comprehensive index of products, living grade water treatment aluminum oxide mass fraction of 30% Above, industrial grade water treatment aluminum oxide mass fraction of 27-29%. Followed by PAC salt base degree
