Description

Polyaluminium Chloride is an acidic solution. Classified as corrosive at higher concentrations, it is typically yellow in colour. It is miscible with water at all concentrations although dilute solutions hydrolyse to precipitate Aluminium Hydroxide (Al(OH)3).
Polyaluminium Chloride is not a single product, but a spectrum of polymers which are characterised by their strength (usually in % Al2O3) and basicity – the latter gives an indication of the polymeric composition of PAC.

Product Information

The main use of Polyaluminium Chloride is in water treatment:

  • Drinking water treatment – coagulant
  • Waste water treatment – coagulant and precipitant
  • Process water treatment – coagulant
  • Effluent treatment – coagulant
  • Swimming pool water treatment – clarification and filtration aid
  • Manufacture of paper
