Product Introduction Poly Aluminium Chloride PAC is an inorganic polymer coagulant. The purification treatment effect is achieved mainly by compressing the double layer, absorbing and electrically neutralizing, absorbing and bridging, sediment net catching and other mechanism actions, so that fine suspended particles and colloid ions in water are destabilized, focused, coagulated and precipitated. Polyaluminium chloride (PAC) is the process of atomizing PAC into tiny particles while it is dried. Raw materials are made of high purity transparent hydrochloric acid, aluminium hydroxide powder and calcium aluminate powder by high temperature and high pressure reaction. The selection of raw materials is exquisite, and the content of heavy metals in raw materials is strictly controlled.
