Properties:

Polyaluminum Chloride(PAC) is an inorganic polymer coagulant, also known as polyaluminum, which is an inorganic polymer water treatment agent with a large molecular weight and high charge produced by the cross-linking of hydroxide ions and the polymerization of polyvalent anions. Polyaluminum Chloride(PAC) is golden yellow, earthy yellow, brown, red granular/flake, purified water quality is better than aluminium sulfate coagulant, water purification cost is 15%-30% lower than it, flocculation formation is fast, sedimentation speed is fast, greater treatment capacity than aluminium sulfate and other traditional products, it can consume water alkalinity lower than various inorganic coagulants, so it can be dosed or have less alkali agent, the pH range of the adapted source water is 5.0-9.0, its corrosiveness is small, the operating conditions are good, and the solubility is better than that of aluminium sulfate. The adaptability to source water temperature is better than that of inorganic coagulants such as aluminium sulfate. The products are widely used in the purification of domestic and production water, domestic sewage, industrial wastewater, the purification and treatment of low-temperature and low-turbid water, the regeneration of wastewater flushing in papermaking, petrochemical, and thermal power plants, and the decolorisation and purification of COD, BOD and SS of printing and dyeing, wool spinning, and wastewater.

Usage:

1.Mix the solid product at room temperature water at a ratio of 1:2.5-1:3 (weight ratio) and stir for about 30 minutes. After PAC is completely dissolved, add 30~40 times the amount of water to dilute or adjust it into liquid form according to the desired concentration before use (the greater the turbidity of the source water, the more water should be added for the second dilution). 
2. When the turbidity of the source water is 100-500mg/L, the dosage is 5-10mg, which means the dosage per 1,000 tons of water is 5-10kg. It is best to conduct a small test according to the water quality characteristics before use to determine the optimal value. Then proceed to use it.
