  • 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.
  • What is poly-Aluminium chloride (PAC)?
  • Poly-Aluminium Chloride (PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.
  • How much PACL is produced in China?
  • The annual requirement and production capacity of PACl in the liquid form has reached 2 million tons in China, and the turnover of PACl has been more than 2 billion Chinese Yuan (equivalent to 310 million US dollars).
  • 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 .
