Polyaluminum chloride (PAC) is an important inorganic polymer widely used in water treatment, sewage treatment, and other industrial applications. It is a mixture formed by polymerization of various aluminum chloride monomers, with high coagulation performance and precipitation ability. The following are the main uses of polyaluminum chloride in different application fields:
Water treatment: PAC is commonly used for purification and coagulation treatment of drinking and industrial water. It can quickly precipitate suspended solids and turbidity, thereby improving water quality and making it clearer. In addition, PAC can also remove heavy metal ions and organic substances from water.
Wastewater treatment: In the wastewater treatment process, PAC is used to condense and precipitate solid particles in the wastewater, while also removing some organic matter and nutrients such as nitrogen and phosphorus from the wastewater.
Pulp and Paper Industry: PAC is used as a water retaining agent and filler in the pulp and paper industry, helping to improve the strength and luster of paper.
Leather Industry: PAC is used as a tanning agent in the leather industry to help dye and improve the texture of leather.
Mining industry: PAC is used to treat mining wastewater, helping to remove solid particles and pollutants from the wastewater.
Oilfield Chemicals: In the process of oilfield development, PAC is used as a dispersant and thickener, which helps to increase the production capacity of oil wells.
Building materials: PAC is also used as an additive in building materials to improve the performance of concrete.
Overall, polyaluminum chloride plays an important role in water treatment, sewage treatment, and multiple industrial fields, helping to improve the efficiency of the environment and production processes.
