Poly Aluminum Chloride (PAC)
ReplyDeletePoly Aluminium Chloride (PAC), is a water-soluble inorganic polymer between AlCI3 and Al(OH)3, its general formula is [Al2(OH)nCl6-nLm], of which m represents the degree of polymerization and n represents the degree of neutrality of PAC products. This product has strong bridge adsorption performance. During the hydrolysis process, condensation, adsorption, precipitation as well as other physical and chemical processes also occurs at the same time. The fundamental difference between pac and traditional inorganic coagulants is that the traditional inorganic coagulants is low molecular crystal salt, but the structure of poly aluminium chloride is composed of polycarboxyl complex with variable morphology, it has high speed of flocculating and precipitating, suitable for wide PH range, no corrosive to pipeline equipment, obvious water purification effect, it can effectively remove chromaticness, Suspended Solids(SS), Chemical Oxygen Demand(COD), Biochemical Oxygen Demand(BOD) and such heavy metal ions as arsenic and mercury in the water. This product is widely used in drinking water, industrial water and wastewater treatment field.
