  • What is polyaluminum chloride (PAC)?
  • Polyaluminum chloride (PAC) is a classic inorganic polymer material, which has the advantages of easy preparation, low cost, and high efficiency in the field of water treatment and other areas of environmental protection [ 1, 2 ].
  • What is a high alkalinity polyaluminium chloride?
  • Polyaluminium chlorides, as trade products, are characterised by alkalinity ranging from 15 to 90%. Coagulants of low alkalinity are characterised by alkalinity below 40%, average alkalinity (from 40 to 70%) and high alkalinity (from 80 to 85%).
  • Does pH affect the performance of polyaluminum chloride (PAC)?
  • The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
  • What is the formula for alkalinity of polyaluminium chloride?
  • Polyaluminium chlorides represented by the general formula Al n (OH) m Cl 3n–m are primarily used. The alkalinity of polyaluminium chloride is determined by the quotient of the number of moles OH − to Al 3+ in a coagulant, referred to as the alkalinity ratio (r), which is approached as a coagulant polymerisation degree measure.
