  • 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 high-purity PACL remove turbidity?
  • Samples taken from the Huangpu River were used to evaluate the coagulation performance of high-purity PACl in comparison with conventional PACl. The results demonstrate that for the whole dose range studied, high-purity PACls removed more turbidity than conventional PACl.
  • Which bauxite is used to prepare high-purity PACL?
  • The sample A exhibited the highest aluminum content (13.7%) and the highest basicity (92.9%). Therefore, the bauxite 1 from He-Nan province which was used to prepare sample A is to be used as the raw material to prepare high-purity PACl.
  • What is the optimum yield of medium polymeric (Al) content in PC species?
  • The optimum yield of medium polymeric (Al) content in PΑC species was predicted to 74.6 %, and the verification experiment result was 73.5 % at 0.5 M, 2.2, 75 °C and 273 min.
