Poly Aluminium Chloride

Poly Aluminium Chloride (PAC) is a highly efficient coagulant used in water treatment. It helps to extract and clump together contaminants, colloidal, and suspended matter, resulting in the formation of floc for removal via filters[^1^][3].

Key points about PAC in water treatment:

  • Coagulation Performance: PAC has been shown to enhance coagulation performance, reducing the ensuing water pH decline appreciably when applied with the right dosage and under appropriate process conditions[^2^][1].
  • Advantages Over Alum: PAC offers several advantages over traditional alum coagulants, including a wider pH range for coagulation, less impact on water pH, and the production of less sludge[^3^][2].
  • Optimal Conditions: The optimal coagulant dose, mixing speed, and operating pH for PAC have been studied to achieve better performance in water treatment[^2^][1].
  • Environmental Impact: PAC is preferred for its lower consumption of alkalinity in the treatment process, which impacts less on pH and thus on the environment[^3^][2].

The use of PAC in water treatment processes ensures better quality treated water and is an effective alternative to traditional coagulants like alum.
