The characteristics of polyaluminium chloride include its general chemical formula [Al2(OH)nCl6-n]m, which has strong bridging adsorption performance. During the hydrolysis process, it purifies water through physical and chemical reactions such as coagulation, adsorption and precipitation.
Polyaluminium chloride (PAC) has many uses, mainly including the following aspects:
Water treatment: Polyaluminium chloride is a high-efficiency flocculant and water purifier, widely used in the purification of drinking water, industrial wastewater and urban sewage. It can remove suspended matter, color, SS, COD, BOD and heavy metal ions such as arsenic and mercury in water to ensure water quality safety;
Industrial application: In the industrial field, polyaluminium chloride is used for the treatment of various industrial wastewaters and waste residues to promote the recovery of useful substances. For example, PAC performs well in wastewater treatment in printing and dyeing, leather, fluorine, heavy metal, oil, papermaking and other industries; in addition, it is also used in paper sizing, sugar solution refining, casting and other processes;
Agriculture and petroleum: In agriculture, polyaluminum chloride can adjust soil pH and improve soil quality. In the petroleum industry, it is used for dehydration treatment to improve oil quality.
Other applications: Polyaluminum chloride is also used for clarification of fruit juice drinks, anti-wrinkle treatment of fabrics in textile factories, and stabilization of cosmetics, etc.
