  • What is polyaluminum chloride (PAC)?
  • First published on 23rd December 2021 Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.
  • Can PAC coagulants contain aluminum precipitates?
  • Some PAC coagulants may contain aluminum precipitates, according to O'Melia and Dempsey (1982) who reviewed work done using a wide variety of PAC formulations.
  • What is Pac made of?
  • The PAC is composed of various forms of aluminum monomers Ala (such as Al 3+, Al (OH) 2+, and Al (OH) 2+, dimer (Al 2 (OH) 24+), trimer (Al 3 (OH) 45+)) and medium polymeric forms Alb represented mainly by [Al 13 O 4 (OH) 24 (H 2 O) 12] 7+ .
  • Can PAC be used to treat drinking water?
  • The performance of PAC for water treatment revealed that the removals efficiencies of turbidity and NOM were reached to 98 % (pH = 7.2) and 86 % (pH = 6.8), respectively, at coagulant dose of 15 mg L as Al. The residual aluminum concentration in the treated water was <0.2 mg L which confirmed that the PAC could be used to treat drinking water.
