Polyaluminum chloride (PAC), also commonly known as water purifier or coagulant, is a water-soluble inorganic high molecular polymer between ALCL3 and AL (OH) 3. The general chemical formula is [AL2 (OH) nCl6-nLm] where m represents the degree of polymerization and n represents the degree of neutrality of the PAC product.
The color of polyaluminum chloride (PAC) is yellow or light yellow, dark brown, dark gray resinous solid. This product has strong bridging adsorption performance. During the hydrolysis process, it is accompanied by physical and chemical processes such as condensation, adsorption and precipitation. Compared with traditional inorganic coagulants. Polyaluminum chloride has a fast flocculation and sedimentation speed, has a wide range of applicable PH values, is non-corrosive to pipeline equipment, and has a significant water purification effect. It can effectively remove SS, COD, BOD, arsenic, mercury and other heavy metal ions in water.
Process classification
1. Drum-type polyaluminum chloride (PAC): Aluminum content is average, water insoluble matter is high, and it is mostly used for sewage treatment.
2. Plate and frame polyaluminum chloride (PAC): It has high aluminum content and low water insoluble matter, and is used for municipal sewage treatment and domestic sewage treatment.
3. Spray-dried polyaluminum chloride (PAC): high aluminum content, low water insoluble matter, fast dissolution rate. Used for drinking water and higher standard water treatment.
