  • 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.
  • How to manufacture polyaluminium chloride?
  • Method for manufacturing polyaluminium chloride with aluminum vanadine and calcium aluminate powder CN104671269A(en) 2015-06-03 Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production
  • What is the basicity of high-purity PACL?
  • The basicity of high-purity PACl can be maintained at about 92% after the adjustment by calcium aluminate (Table 3), it has exceeded the national and international standards of PACl.
  • 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 ].
