Clarifiers
Clarifiers are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. These tanks are designed to separate solids from liquids by allowing the heavier particles to settle to the bottom while the lighter particles float to the surface.
Function
The primary function of clarifiers is to remove suspended solids, sediments, and other impurities from water or wastewater. They play a crucial role in the treatment process by improving water quality and reducing the concentration of pollutants.
Design
Clarifiers are typically designed with a central feed inlet that allows the water to enter the tank at a controlled rate. The flow velocity is reduced within the tank, allowing the solids to settle out. The settled solids are then collected at the bottom of the tank and removed through a sludge discharge mechanism.
Types
There are different types of clarifiers, including circular clarifiers, rectangular clarifiers, and inclined plate clarifiers. Each type has its own advantages and is selected based on the specific requirements of the treatment system.
Importance
Clarifiers are essential components of water and wastewater treatment plants as they help in the removal of solids, which can cause harm to the environment if discharged untreated. They also help in the clarification and disinfection of water, making it safe for human consumption and other uses.
In conclusion, clarifiers are crucial for the efficient treatment of water and wastewater by continuously removing solids deposited by sedimentation. Their mechanical design ensures the proper separation of solids, contributing to the overall quality of the treated water.
