Polyaluminum chloride has the properties of adsorption, agglomeration, and precipitation. It has poor stability and corrosiveness. If it accidentally splashes on the skin, it must be rinsed off immediately with water. Production personnel wear overalls, masks, gloves, and rubber boots. Polyaluminum Chloride has the advantages of good spray drying stability, wide adaptability to water area, fast hydrolysis rate, strong adsorption capacity, large pod formation, fast density sedimentation, low effluent turbidity, and good dehydration performance. Spray drying products can ensure safety, reduce water accidents, and provide safe and reliable drinking water for residents. Therefore, polyaluminum chloride is also referred to as high-efficiency polyaluminum chloride, high-efficiency PAC or high-efficiency spray-dried polyaluminum chloride. Polyaluminum chloride is suitable for raw water of various turbidity, and has a wide range of pH application, but compared with polyacrylamide, its sedimentation effect is far inferior to polyacrylamide.
The degree of alkalinity of polyaluminum chloride is a relatively important indicator in polyaluminum, especially for drinking grade polyaluminium products. The lower the basicity of salt, the higher the price, and the buyers can operate according to the actual situation of the manufacturer. In addition, the basic degree of polyaluminium chloride produced by different raw materials and processes for different processes is also different, which requires manufacturers to make adjustments. Raising the base degree of polyaluminum chloride products can greatly increase the economic benefits of production and use. The basicity of salt is increased from 65% to 92%, the raw material cost can be reduced by 20%, and the use cost can be reduced by 40%.
