polymeric aluminum chloride is an inorganic polymer coagulant. mainly through the compression of the bilayer, adsorption and charge neutralization, adsorption bridging, sediment trap the role of such mechanism, so that the water fine suspended particles and colloidal ion destabilization, aggregation, flocculation, coagulation, sedimentation, achieve the purification effect. the product compared with other coagulants,
has the following advantages:
l, wide application range, wide adaptation in the water.
2, easy to rapidly form a big alum, settling performance.
in 3, the suitable ph range (5 - 9 ), and the processed water ph value and alkalinity decreased small.
in 4, when the water temperature is low, still can maintain stable precipitation effect.
5, basicity than other aluminum salt, ferric salt is high, equipment erosion effect.
high purity polyaluminum chloride ( pac ), is a grade aluminum hydroxide powder and high purity hydrochloric acid by high pressure reaction and refined white powder. mainly used in papermaking, medicine, daily chemicals, cosmetics additive and process for drinking water purification
