  • Polyaluminum chloride: Used to attract particles together.
  • Soda Ash: Used to adjust pH for chemical treatment.
  1. Flocculation
  • This process is a slow mix of the water and chemicals. As the chemicals and small particles come into contact with each other, the small particles begin combining together to form bigger particles.
