What is polyaluminum chloride?
Polyaluminum Chloride (Poly aluminium chloride) is short of PAC. It is a type of water treatment chemical for drinkingwater, industrial water, wastewater, groundwater purification for color removing. COD removing.etc by reaction. It can beregarded as a type of flocculate agent, decolor agent or coagulant either. PAC is a water-soluble inorganic polymers between ALCL3 and AL(OH)3, the chemical formula is [AL2 (OH) NCL6- NLm]m’ refer to the extent of polymerization, ‘n’stand for the neutral level of PAC products. It has the advantages of low cost,less consumption, and an excellent purification effect. How many types of PAC? here are two prodcing methods one Is drum drying. the other is spray drying. Due to diferent production line, there are a little differences from both the appearance and the contents.Drum drying PAC is yellow or dark yellow granules, wth a content of AL2O3 from 27% to30%. The insoluble material inwater is not more than 1%. While Spray Drying PAC is yellow, pale yellow or white color powder, with a content of AL2O3 from 28% to 32%. The insoluble material in water is not more than 0.5%. How to choose the right PAC for different water treatment? There is no defination for PAC application in watet treatment. Itis only a standard of PAC specifcation requirement indifferent water treatment. Standard No. for drinking water treatment is GB 15892-2009 Usually, 27-28% PAC is used in non-drinking water treatment, and 29-32% PAC is used in drinking water treatment.
