  • What is polyaluminium chloride?
  • Polyaluminium Chloride (PAC) is an inorganic polymer coagulant. It is a yellow solid powder that is widely used in water treatments. PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC.
  • Does polyaluminium chloride coagulate with non-prehydrolysed aluminium salts?
  • Although the mechanism of coagulation with non-prehydrolysed and prehydrolysed aluminium salts is the same, the presence of polymeric forms of aluminium in polyaluminium chloride solutions makes them more stable in water, providing more effective removal of impurities and lower concentrations of aluminium remaining in the treated water.
  • Does polyaluminium chloride coagulation reduce water pollution?
  • The aim of this study was to evaluate the effectiveness of the coagulation process using highly polymerised polyaluminium chlorides in reducing the level of pollution of water in a mixture of groundwater and surface water.
  • What coagulants are used in coagulation of polyaluminium chlorides?
  • The coagulants used were prehydrolysed polyaluminium chlorides with the trade names PAXHP908 and PAXXL1911 that had an alkalinity of 85%, different iron contents (<0.01% and 0.7%) and the same content of polymerised aluminium forms (Al b = 40%).
