PAC (Poly Aluminium Chloride) is white, light gray, light yellow or brown crystals or powders. The color varies with the production process and raw materials. It is slightly acidic. After dilution with water, aluminum hydroxide precipitates. In the hydrolysis process, physical and chemical processes such as electrochemistry, coagulation, adsorption and precipitation are accompanied, so as to achieve the purpose of water purification.
(1) Low dosage than Aluminium sulfate, low cost;
(2) Quick formation of big flocs and rapid precipitation.
(1) For solid PAC, dilution is necessary before being dosed. Dilution proportion for solid product is 2%-20%, and for liquid product, 5%-50%(based on weight percentage).
