PolyaluminChloride, abbreviated as PAC, is an inorganic polymer made by processing high-quality aluminum hydroxide powder through a series of processes. It is a water-soluble inorganic polymer between AlCl3 and Al (OH) 3, with the chemical formula (AL2 (OH) Ncl6 nLm), and its color is yellow and light yellow powder granular solid. This product is non-toxic, odorless, and non corrosive, with functions such as deodorization, decolorization, turbidity removal, and sterilization. It is prone to moisture in the air, but it does not affect the effectiveness of use. After adding polyaluminum chloride to water, it has high decomposition activity, fast settling, and is not affected by any additives, water temperature, or water quality. Urban water supply and drainage purification: river water, reservoir water, groundwater, industrial water supply purification, urban sewage treatment, recovery of useful substances in industrial wastewater and waste residue, promotion of coal dust sedimentation in coal washing wastewater, recovery of starch in starch manufacturing industry, various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluoride containing wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment, papermaking auxiliaries, cloth reinforcement, catalyst carrier, pharmaceutical refining, cement rapid setting, cosmetics raw materials, etc.

Polyacrylamide PAM is used as a retention aid and reinforcement agent in the papermaking process. Used as a coagulant aid, flocculant, and sludge dewatering agent in water treatment. Used as a precipitation agent and oil displacement agent in oil drilling and production. PAM is also widely used in thickening, stabilizing colloids, reducing drag, bonding, film-forming, biomedical materials, and other fields.

Polymerized ferric sulfate, urban water supply and drainage purification: river water, reservoir water, groundwater, industrial water supply purification, urban sewage treatment, recovery of useful substances in industrial wastewater and waste residue, promotion of coal dust sedimentation in coal washing wastewater, recovery of starch in starch manufacturing industry, various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluoride wastewater, heavy metal wastewater, oil-bearing wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment, papermaking auxiliaries, cloth reinforcement, catalyst carrier, medical drug refining, cement quick setting, cosmetics raw materials, etc. The commonly used chemicals in wastewater treatment can be divided into organic phosphine solid series scale and corrosion inhibitors, organic phosphine liquid series scale and corrosion inhibitors, organic phosphine salt liquid series, polycarboxylate scale and dispersant, bactericidal and algal killing agents, clay stripping agents, composite special scale and corrosion inhibitors, cleaning pre film agents, copper and acid pickling corrosion inhibitors, flocculants, etc. according to their different uses.
