Quickly determine the quality of polyaluminum chloride from where to start? Quickly determine the quality of polyaluminum chloride from where to start? How to determine whether the high efficiency of PAC? Simple way to save energy is to see how the strength of manufacturers and after-sales service, if ten of the ten customers say good, then the manufacturer of PAC quality is certainly very good, more professional level is to learn to go Judging the true good and bad, Gongyi City, filter material purification materials factory parents to the quality and credibility of the speaker, strong technical force, advanced production technology, sophisticated processing, testing equipment, products meet the national standards, welcomed by the new and old customers. How quickly experts can determine the quality of PAC, and can accurately determine whether the treatment of sewage or drinking water, and some directly from the color of the PAC can be very intuitive to distinguish between the quality of good The bad, first of all, to talk about the less common white polyaluminum chloride, because it is known as high purity Wu Fe white aluminum chloride, or food grade white polyaluminum chloride, compared with other polyaluminum chloride is the highest quality Products, white polyaluminum chloride for dry paper sizing agent, sugar decolorizing clarifier, medicine, cosmetics and precision casting and water treatment and other fields, the main raw material is high-quality aluminum hydroxide powder, hydrochloric acid, used Production technology is the most advanced technology spray drying method. Due to the high cost of white polyaluminum chloride, it is rarely used in water treatment, generally with yellow spray-dried polyaluminum chloride instead, to say yellow polyaluminum chloride, its raw material is calcium aluminate powder , Hydrochloric acid, bauxite, the main sewage treatment and drinking water treatment, if used for drinking water treatment is aluminum hydroxide powder, hydrochloric acid and a little calcium aluminate. As the treatment of drinking water in the country has strict requirements on heavy metals, so both raw materials and production processes are better than the polyaluminum chloride, Gongyi City, we filter filter material manufacturers talk about what is tan polychlorinated Aluminum, its raw material is calcium aluminate powder, hydrochloric acid, bauxite and iron powder, the production process is the use of drum drying method, generally used mainly for sewage treatment, because it added iron powder if more than a certain amount of a Also called PACs for some time, they have excellent results in wastewater treatment.
