Water Clarifier/ Clarification

Clarifiers are used for the purpose of clarification of wastewater. Clarification is the widely accepted and the oldest used method in the effective treatment of water and wastewater. This operation includes removal of sediment, floating material and turbidity from raw wastewater. There are two types of clarifier. One is circular center feed clarifier that operates with the effluent entering through a center stilling well. It ensures proper residence time of the water in the clarifier to allow for the settling of the solids. The water rises and exits through a wall mounted weir. Other type of clarifier is the circular peripheral flow clarifier. It operates with the water flow entering the system at the periphery. The water flow is distributed evenly and spirals down around the annulus of the clarifier. It is done by means of a specially designed baffle skirt. This configuration provides maximum settling of solids toward the sludge pick-up.


Types of Water Clarifier
On the basis of applications water clarifiers can be categorized as:

• Reactor Clarifier
• Circular Clarifier
• Rectangular Clarifier
• Flocculator Clarifiers
