Polyaluminum Chloride PAC Industrial Wastewater Treatment Municipal Wastewater Treatment Chemicals
Polyaluminum chloride is between ALCL3 and ALNCL6-NLm] where m represents the degree of polymerization and n represents the neutrality of the PAC product. Polyaluminum chloride abbreviated as PAC is usually also called polyaluminum chloride or coagulant, etc., the color is pale or pale, dark brown, dark gray resin-like solid. The product has strong bridging adsorption performance. During the hydrolysis process, physical and chemical processes such as condensation, adsorption, and precipitation occur.

|Basicity of salt||40-90%|
|PH (1%water solution)||3.5-5|
Polyaluminum chloride is mainly used for 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 the sedimentation of coal powder in coal washing wastewater, starch manufacturing Recovery of medium starch; polyaluminum chloride can purify various industrial wastewater, such as: printing and dyeing wastewater, leather wastewater, fluorine wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat Processing wastewater, etc.; wastewater treatment by polyaluminum chloride: paper sizing, sugar liquid refining, casting molding, cloth anti-wrinkle, catalyst carrier, pharmaceutical refined cement quick-setting, cosmetic raw materials.
2. Phosphorus removal
Add chemicals to the sewage to make the phosphate ions in the water generate insoluble salts, which will be separated from the water after the formation of flocs, thereby removing the phosphorus contained in the water. In the specific reaction process, there are two main reaction processes. First, the trivalent aluminum ion reacts with the phosphate and precipitates, and the precipitated compound is AlPO4.
1.When used as sewage treatment chemicals, polyaluminium chloride offers better water treatment effects than aluminum sulfate flocculant, while the cost is also lowered by 15-30%.
2.The generating speed and sedimentation speed of the flocculating constituent is quite fast. The treating capacity is also much greater than that of traditional wastewater treatment chemicals like aluminium sulfate.
3.The alkalinity of treated water has smaller reduction, comparing with that using inorganic flocculants. Thus less or no alkaline agents is needed.
4.The suitable water PH range is 5.0-9.0.
5.Low level corrosivity.
6.Safe and easy using procedure.
7.Polyaluminium chloride offers better solubility than aluminum sulfate.
8.The salinity in treated water has limited rise. It is good for ion exchange treatment and high purity water production.
