PAC(Polyaluminum chloride)
Poly aluminium chloride is a specific aluminum salt of aluminium chlorohydrate, and it is also simply called PAC. The general chemical formula is [Al2(OH)nCl6-n]m (1≤n≤5,m≤10). CAS No.: 1327-41-9.
PAC Applications
1.It is used to make waste water recyclable in industries. such as paper-making glue, printing and dying, concrete hardener, precision casting hardener, glycerine refinement, crease-resistant for fabric, medicine, cosmetics and etc.
2.It has good effects on oil-water separation in the oil refining industry.
3.It is used as a coagulant in the treatment usage of drinking water purification and sanitary sewage.
4. It is used as a flocculant in the treatment usage of Industrial water, industrial wastewater, mine and water for oilfield injection, chemical wastewater in the industry of paper-making, metallurgy, washed coal, sludge water treatment,effluent treatment from civil engineering works,and leather.
5. It can also be used as a phosphorus remover. When polyaluminum chloride is added to the sewage, the phosphate ions in the water are formed into insoluble salts, and the flocs are formed and separated from the water, thereby removing the phosphorus contained in the water.
1.Yellow Powder Polyaluminium chloride
The raw materials of yellow polyaluminum chloride are calcium aluminate powder, hydrochloric acid, and bauxite, which are mainly used for sewage treatment and drinking water treatment. The raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid, and a little calcium aluminate powder.
2.Yellow Granular Polyaluminium chloride
The raw materials of yellow polyaluminum chloride are calcium aluminate powder, hydrochloric acid and bauxite. They are mainly used for sewage treatment and drinking water treatment. The manufacturing process is drum drying.
3.White Polyaluminium chloride
White polyaluminium chloride is a high purity iron-free product with the highest quality. White polyaluminum chloride is used in paper sizing agents, sugar bleach clarifiers, pharmaceuticals, cosmetics, precision casting and drinking water treatment.
4.Brown Granular Polaluminum chloride
Tan polyaluminum chloride production process adopts drum drying method, which is generally mainly used for various industrial wastewater treatment, and has excellent effect on the surface of sewage treatment.
Features Adsorption, aggregation, precipitation and other properties Adapt to the wide range of water Fast hydrolysis Strong adsorption capacity Formation of alum Fast sedimentation Low effluent turbidity Good dehydration performance Suitable for raw water with various turbidity Wide application range of pH But compared with polyacrylamide, its sedimentation effect is far inferior to polyacrylamide. etc. This material removes suspended materials more effectively based on high charge destabilizing characteristics. It is the best choice between aluminium sulfate, aluminium chloride and polyaluminium chloride PAC.
