  • 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.
  • Why is PACL not used in drinking water treatment?
  • In addition, harmful ions such as Pb, Co, Cu and As from the raw materials (bauxite and calcium alumina) are normally remained in the product PACl, which restricts the application of PACl in drinking water treatment. Such PACls are only used for industry effluent and sewage treatment .
  • What is the molecular formula of poly-aluminum chloride?
  • One of the major pre-polymerized coagulants, poly-aluminum chloride (PACl) is used broadly for water and wastewater treatment. PACl contains different amounts of hydroxyl, and the molecular formula of PACl is [Al m (OH) n (H 2 O) x]·Cl 3m−n (n ≤ 3 m).
  • What are the quality control parameters for the production of PACL?
  • The aluminum content and the basicity are the most important quality control parameters for the production of PACl. Currently, calcium aluminate is widely used to adjust the basicity; the resulting PACl products possess good stability which is suitable for long term storage .
