Poly Aluminium Chloride (PAC) is a widely used water treatment chemical. It’s an inorganic polymer with a high molecular weight, containing aluminum, chloride, and hydroxide ions.

How does PAC work?

PAC works as a coagulant, neutralizing the charges of suspended particles in water. This causes the particles to clump together, forming larger flocs that can be easily removed through sedimentation or filtration.

Key applications of PAC:

• Water Treatment:
  • Used to treat drinking water, wastewater, and industrial wastewater.
  • Removes turbidity, color, and other impurities.
• Paper Industry:
  • Used as a sizing agent and retention aid in papermaking.
• Textile Industry:
  • Used as a mordant in dyeing and finishing processes.

Advantages of using PAC:

• High Efficiency: PAC is highly effective in removing a wide range of contaminants.
• Low Dosage: Requires lower dosage compared to traditional coagulants.
• Rapid Floc Formation: Leads to faster sedimentation and clarification.
• Reduced Sludge Volume: Produces less sludge, reducing disposal costs.
• Environmental Friendliness: Less harmful to the environment compared to some other coagulants.

By understanding the properties and applications of PAC, industries can optimize their water treatment processes and achieve better results.
