Poly Aluminum Chloride
CedarCLEAR Poly Aluminum Chloride coagulants offer superior
performance in many water treatment applications. Varying in terms
of their aluminum concentration and basicity, these products make it
possible to find a suitable treatment for almost every potable,
wastewater or industrial application.
What is Poly Aluminum Chloride?
Poly Aluminum Chloride, also known as PAC or PACl is a
pre-polymerized aluminum coagulant that is very different than many
Common organic polymers used in water treatment. It lowers the
overall pH, just as traditional coagulants like alum or ferric
chloride. However, the presence and level of the OH ions in poly
aluminum chloride (referred to as basicity) reduces the magnitude of
the pH depression. This affects the degree to which the
aluminum molecules in poly aluminum chloride gain a higher
charge, making them more effective at coagulating the

charged turbidity, suspended solids and
phosphorous in raw water. The higher charge Poly Aluminum Chloride
allows less aluminum to be added. Hence less hydroxide is formed and
the amount of sludge is reduced.
Plants typically observe sludge reductions up to 50-75%.
Our CedarCLEAR Poly Aluminum Chloride will generally produce the
following results when compared to traditional coagulants:
• Reduced Sludge Production
• Lower Dosages
• Lower Alkalinity Consumption
• Wider Working pH Range
• Improved Cold-water Performance
• Improved Filter Operation
• Faster Floc Formation
• Improved Settled Turbidities |
