What are the effective ingredients of polyaluminum chloride

When most people buy polyaluminum chloride, they will directly say how much content they want. The content here refers to the content of alumina (Al2O3) in polyaluminum chloride, which is the active ingredient of polyaluminum chloride products. Simply put, the effective component of polyaluminum chloride is the content of alumina (Al2O3) in polyaluminum chloride.

        The content of aluminum oxide (Al2O3) in polyaluminum chloride ranges from 22% to 30%, and the effect is different if the content is different.

        Alumina content is a measure of the effective components of polyaluminum chloride, and it has a certain relationship with the specific gravity of the solution. Generally speaking, the higher the specific gravity, the higher the alumina content. However, the relationship between the two varies with factors such as temperature, impurities, manufacturing methods, and basicity. Polyaluminum chloride contains impurities, which will affect the specific gravity and alumina content. The relationship between basicity and contrast weight and alumina has a more direct effect. With the same alumina content, the lower the basicity, the greater the specific gravity. Therefore, the active ingredients of the product cannot be quantified by specific gravity.

        In water treatment, polyaluminum chloride not only has good flocculation performance, but also has the advantages of rapid formation of large flocs, good mechanical strength, and high settling speed. Used for high turbidity water, low temperature and low turbidity water, colored water and contaminated water, it can achieve good flocculation effect, and has relatively good changes in the pH value, temperature, turbidity, alkalinity, organic matter, etc. of raw water. Strong adaptability. And when the turbidity of the raw water increases, the increase in the dosage is small.

        Practice has proved that within a certain range, the higher the turbidity of the raw water, the greater the range of turbidity changes, and the more obvious its superiority. Therefore, the content of alumina (Al2O3) is closely related to the active ingredient of polyaluminum chloride.
