  • Can high-basicity polyaluminum chloride and high-viscosity chitosan be used for?
  • This study evaluated the feasibility of integrating high-basicity polyaluminum chloride (PAC) and high-viscosity chitosan for the coagulation of low-temperature and low-turbidity water. The effects of PAC basicity on coagulation performance and residual Al control were also investigated.
  • What is a high basicity PAC?
  • The PAC with high basicity (70% basicity) has become popular due to its higher removal efficiency of MON, low residual aluminum content in the treated water, and high stability during storage .
  • 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.
