  • 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 ].
  • 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.
  • Can polymers be used with Pac coagulant for ceramic wastewater treatment?
  • The purpose of this stage of jar-test experiment was to identify the suitable dose of polymers, which could be used in combination with optimal dose of PAC coagulant (300 mg/L) for treatment of the ceramic wastewater. The applied polymer dose varied from 0.5 to 3 mg/L.
  • Can PAC be prepared from aluminum chloride solution?
  • PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [ 16, 21 ], sodium hydroxide [ , , ] and sodium aluminate [ 25 ].
