  • What is poly Aluminium chloride?
  • This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
  • Why is poly Aluminium chloride used in water treatment?
  • The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
  • What is powdered polyaluminium chloride?
  • Powdered polyaluminium chloride is produced from the reaction of hot HCl gas with an aluminium substrate producing a dry material. Powdered PolyAC is available as a white powder which comes in 20 or 25 kg bags.
  • What are the chemical requirements of polyaluminium chloride?
  • The chemical requirements of both forms of polyaluminium chloride are given below. Powdered PolyAC shall contain water-soluble aluminium of not less than 14 ± 0.3% w/w as Al, or 30% w/w as Al2O3. Liquid PolyAC shall contain water-soluble aluminium of not less than 2.16% w/w as Al or 10% w/w as Al2O3.
