What is Clarifiers?
Figure 02: What is Clarifiers?

Offering multiple key benefits:

Types of Clarifiers:

  • Sedimentation Clarifiers: Sedimentation clarifiers are among the most frequently employed types of clarifyers. Also referred to as settling tanks or sedimentation basins, gravity is used to separate suspended solids and water by forcing solid particles with higher densities down towards the bottom of the clarifier until they settle at its center and form a thick mass known as sludge; at which time water on top becomes clarified.
  • Coagulation-Flocculation Clarifiers: Coagulation-Flocculation clarifiers go beyond sedimentation by using chemical processes to increase particle removal. Water treated with coagulants neutralize charges on suspended particles to form larger flocs more easily settle during sedimentation for better particle removal.
  • Dissolved Air Flotation Clarifiers (DAFs): DAF clarifiers employ micron-sized air bubbles to separate particles suspended in water from its surface. When introduced into the solution, these microscopic air bubbles attach themselves to floating particles which rise to the top, where they will eventually be skimmed off before leaving only clarified water behind.

Benefits of Clarifiers:

  • Clarifiers enhance water clarity: By filtering out suspended particles, sediments, and solids that create murkiness in the water.
  • Reduction of Organic Matter: Clarifiers are capable of creating clearer and cleaner waters with reduced turbidity levels. They’re even equipped to eliminate bacteria, algae and other microorganisms which taint it further enhancing quality in this regard.
  • Clarifiers Are Key Components in Treatment Processes: By filtering solids out, clarifiers reduce the burden on subsequent steps in treatment such as filtering or disinfection and may help avoid damage and blockages by clearing away large particles that cause blockages in pipes or drains.
  • Prevention of Clogging and Damage: Consequently, clarifiers help improve efficiency by making treatment processes more cost effective.

Examples of Clarifier Applications:

  • Clarifiers: Clarifiers are integral parts of water treatment plants, serving to filter out solid particles before further treatment takes place.
  • Industrial Applications: Clarifiers can be found in industries as diverse as chemical production, mining, food processing and preparation to filter pollutants out of wastewater before discharging or recycling it for reuse.
