  • Is polyaluminum chloride a good coagulant for water treatment?
  • Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
  • 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 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 ].
  • Is monomeric aluminum chloride a basification agent?
  • In this study, monomeric aluminum chloride was used as the main raw material and calcium oxide as the basification agent. The monomeric aluminum chloride (hexahydrate form) was extracted from Ethiopian kaolinite using hydrochloric acid and its purity was >98 % [ 28 ].
