PAC (Polyaluminium Chloride) referred to as PAC. Usually referred to asBasic aluminum chloride or Coagulant, etc. Which is a water-soluble inorganic polymers between ALCL3 and AL(OH)3 between, chemistry general formula [AL2 (OH) NCL6 - NLm], m is degree of behalf of polymerization, n said that the neutral level of PAC products. A kind of resin-like solid which apperance is yellow or light yellow, dark brown, dark gray. The product has a strong bridge adsorption performance, during the hydrolysis process, accompanied by cohesion occurs, adsorption and precipitation and other physical chemical processes.
PAC and the fundamental difference between traditional inorganic coagulant is the traditional inorganic coagulant for the low molecular weight crystalline salt, the structure of the PAC by the carboxyl form complex multi-variable composition, coagulation and sedimentation speed, for pH value, wide range of pipeline equipment, non-corrosive, water purification effect is obvious, can effectively support the water-color quality except SS, COD, BOD, and arsenic, mercury and other heavy metal ions, the products are widely used in drinking water, industrial water and wastewater treatment area.
