PAC (Polyaluminium Chloride) referred to as the PAC. Usually referred to basic aluminum chloride or coagulant, it is between ALCL3 and AL (OH) 3 between a water-soluble inorganic polymers, chemical formula is [AL2 (OH) NCL6-NLm] where m represents the degree of polymerization, n represents a neutral level of PAC products. color yellow or pale yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption properties, in the hydrolysis process, accompanied by condensation, adsorption and precipitation and other physical and chemical processes occur.
PAC is an inorganic polymer coagulant mainly by compressing double, adsorption charge neutralization, bridging adsorption, precipitation was netting mechanism of action, so that the water fine particulates and colloidal ion destabilization, aggregation, flocculation, coagulation, sedimentation, to purify the treatment effect of the product compared with other coagulants, has the following advantages:. l, a wide range of applications, adapt aqueous 2 wide, easy to quickly form large alum, precipitation good performance. 3, suitable for a wide range of PH value (5-9 rooms), and the treated water PH value and alkalinity decrease little. 4, the water temperature is low, you can still maintain a stable sedimentation effect. 5, alkalized degree than other aluminum, iron high, equipment for small erosion.
