What are the main uses of poly aluminium chloride?

Poly aluminium chloride has multiple uses, including:

  1. Water Treatment: It is primarily used in municipal and industrial water treatment facilities to purify drinking water and treat wastewater.
  2. Pulp and Paper Industry: This chemical helps in enhancing the paper-making process by improving the retention of fine particles and fillers.
  3. Textile Industry: In textile processing, poly aluminium chloride is used for dye fixing and improving color retention.
  4. Cosmetics: It can also be found in some cosmetic products as an astringent and to improve product stability.
  5. Construction: Poly aluminium chloride is used in the construction industry for stabilizing and solidifying soils.

How does poly aluminium chloride work in water treatment?

In water treatment, poly aluminium chloride acts as a coagulant. But how does this process work? Here’s a simple breakdown:

  1. Coagulation: When poly aluminium chloride is added to water, it neutralizes the negative charges on suspended particles. This neutralization helps particles stick together to form larger clusters called flocs.
  2. Flocculation: These larger flocs can then be easily removed from the water through sedimentation or filtration.
  3. Clear Water: As a result, the water becomes clearer, making it safer for human consumption and the environment.

Are there any environmental concerns associated with poly aluminium chloride?

While poly aluminium chloride is highly effective, there are some environmental considerations to be aware of:
