  • What is clarification in water treatment?
  • Clarification, or sedimentation, is an essential part of the process in wastewater and drinking water treatment. It consists in removing suspended solids (TSS) through gravity or mechanical means in a clarifier basin.
  • What is a water clarification system?
  • These clarification systems are commonly used in drinking water , process/intake water, and wastewater treatment applications. Coagulation intends to neutralize the electrical charges of floating particles, stopping them from repelling one another within the water.
  • How does a clarifier work?
  • The clarified water instead is released over overflow weirs on the top of the clarifier. In properly functioning clarifiers the overflow water looks already very clear. Fats, oil, grease and other floating substances are removed by a rotating skimmer on the water surface.
  • How does a wastewater treatment clarifier work?
  • The same principle is used by wastewater treatment clarifiers: Large tanks provide enough retention time to slow water down and to separate out suspended particles. Wastewater from aeration basins is usually entering the clarifier from a centrally located pipe.
