The difference between powdered and granular polyaluminum chlorides in water treatment applications The difference between powdered and granular polyaluminum chlorides in water treatment applications Polyaluminum chloride is available in many varieties and today we discuss What is the difference between powder and granular PAC, which is accepted and approved by the user in the water treatment. First of all, let us first understand the powder polyaluminum chloride, the appearance of the product is yellow or pure white powder, the delicate degree is like flour, which is the most advanced production technology at home and abroad - spray drying method of production To the raw materials are high-quality aluminum hydroxide, hydrochloric acid and other reaction processing), the higher the effective content for the treatment of water quality is also more excellent. The only use of the production process is more stringent, the product is insoluble in water is very low, and the powder polyaluminum chloride dissolved in colorless transparent liquid or light yellow transparent liquid. The indicators can reach or due to national standards. The granular products are less, granular aluminum chloride mainly produced by the frame filter press or natural precipitation by drum drying products, and the product is dissolved after the yellow turbid liquid. Its products in the effective content can also reach the national standard, but in the dissolution time is not as good as powder aluminum chloride, particle aluminum chloride used in raw materials for the calcium aluminate, hydrochloric acid, bauxite mixed processing to make. Generally speaking, the use of powder polyaluminium chloride is more broad, in addition to water treatment, it can also be used in paper sizing, cosmetics, food and other fields. The price of its products is also much more granular aluminum chloride, particle polyaluminum chloride is mainly used in the field of sewage treatment or drinking water, the price is relatively low. This requires the use of units at the time of purchase, please indicate your use, the company professionals will recommend for you more cost-effective products.
