  • 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 reduce operating cost?
  • On the other hand, when the dose was greater than 4 mg L −1 as Al, the high-purity PACl showed great UV 254 -absorbance removal capacity; which was even much greater at high does (e.g., 10 mg L −1). Relative low dose requirement of high-purity PACl indicates the potential of the reduction of operating cost.
  • 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 .
