  • What is high-purity poly-aluminum chloride (PACL)?
  • Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
  • 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 poly aluminum chloride (PAC)?
  • Poly Aluminum Chloride (PAC) has emerged as a game-changer in the realm of water treatment, redefining the landscape with its multifaceted benefits.
  • Which polymers are used to make high-purity PACL?
  • After PACl was prepared, the polymers with a sulfydryl group and modified PAM were added into the conventional liquid PACl, this not only removes iron significantly, but also accelerates the sedimentation of insoluble suspended matter. The properties of high-purity PACl synthesized by bauxite and calcium aluminate are shown in Table 3.
