Coagulants

Poly Aluminum Chloride (Liquid)

PAC+ can be used as a flocculant for all types of water treatment treatment, drinking water, industrial waste water, urban waste water and in the paper industry.

The possible slightly higher unit price of PAC+ is compensated by a,

  • Lower dosage requirement
  • No requirement for any neutralising agent (soda, lime)
  • Shorter flocculation time
  • Smaller amount of sludge
  • Reduced number of back washing steps
  • Higher quality of the treated water
