Product Description

Quality index of PAC (polyaluminum chloride)
What are the three most important quality indicators of PAC (polyaluminum chloride):
1,Salinity.

The degree of hydroxylation or alkalization of a certain form in PAC (polyaluminum chloride) is called the degree of basicity or alkalinity. It is generally expressed by the molar ratio of aluminum hydroxide B=[OH]/[Al] percentage. The salinity is one of the most important indicators of polyaluminum chloride, which is closely related to the flocculation effect. The higher the raw water concentration and the higher the salinity, the better the flocculation effect.

2,pH value.

The pH of the PAC (polyaluminum chloride) solution is also an important indicator. It represents the amount of OH- in the free state in solution. The pH value of polyaluminum chloride generally increases with the increase of the basicity, but for liquids with different compositions, there is no corresponding relationship between the pH value and the basicity. Liquids with the same salinity concentration have different pH values when the concentration is different.

3,alumina content.

The alumina content in PAC (polyaluminum chloride) is a measure of the effective components of the product, which has a certain relationship with the relative density of the solution. Generally speaking, the greater the relative density, the higher the alumina content. The viscosity of polyaluminum chloride is related to the alumina content, and the viscosity increases with the increase of alumina content.5. The difference in the color of polyaluminum chloride (PAC)
