Product Description

Poly aluminium chloride has adsorption, agglomeration, precipitation and other properties, with poor stability and corrosiveness. If it splashes on the skin, it should be washed with water immediately. Production personnel shall wear work clothes, masks, gloves and long rubber boots. Polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to the water area, fast hydrolysis speed, strong adsorption capacity, large alum forming, high quality and fast sedimentation, low turbidity and good dewatering performance. Spray drying products can ensure safety and reduce water accidents. It is very safe and reliable for drinking water. Therefore, poly aluminum chloride is also referred to as highly effective polyaluminum chloride, highly efficient PAC or highly efficient spray drying polyaluminium chloride. Polyaluminium chloride is suitable for all kinds of turbidity raw water, and its pH range is wide.


Concentration ratio method
When solid polyaluminium chloride is diluted into liquid, first of all, according to the situation of raw water, a small test should be done before use to obtain the best dosage. When PAC is used in production, it can be dissolved according to the mass ratio of PAC solid: clear water = 1:9-1:15. The solution with alumina content less than 1% is easy to hydrolyze, which will reduce the use effect, and the solution with too high concentration is not easy to be added evenly. After the agent is put into use, if the alum in the sedimentation tank is small and the residual turbidity is large, the dosage is too small; if the alum in the sedimentation tank is large and turned up, the dosage is too large, which should be adjusted appropriately.

The PAC can be used in treatment of various industrial wastewater: printing and dyeing wastewater, leather wastewater, fluoride wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater and wastewater treatment.
