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.
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.
- 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.
- Optimal Conditions: The optimal coagulant dose, mixing speed, and operating pH for PAC have been studied to achieve better performance in water treatment.
- 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.
The use of PAC in water treatment processes ensures better quality treated water and is an effective alternative to traditional coagulants like alum.
