WTE offers a wide range of clarifier systems like High Rate Solid Contact Clarifier (HRSCC), Tube Settler, Clariflocculator, Lamella Settler, etc. to handle wastewater & surface water. Clarifiers are extensively used for the continuous mechanical removal of settleable solids from water and wastewater. This assembly is designed to meet the client’s requirements and is available in different specifications as per the application.
Clarifiers are mechanical means for continuously removing solids that are being deposited. It is generally used to remove solid particulates or suspended solids from liquid for clarification or thickening.

A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening.
The clarifier serves the purpose of reducing suspended solids and colloidal silica & removal of heavy metals. The Solids Contact Clarifier works on two basic principles of coagulation/Flocculation and Hydraulic Separation. Coagulation & Flocculation occur in the flocculation zone when the feed stream comes in intimate contact with chemical mixtures and the suspended sludge particles from previously treated water. This contact also promotes floc growth as smaller particles agglomerate into larger heavier particles. The Hydraulic separation principle uses an up-flow design to move water into the settling zone for clarification.
HRSCC internals of the tank includes draft, recirculate, flash mixer, gearboxes, inlet, and outlet collection launders. Along with the chemical dosing system.
In order to clarify or thicken a liquid, solid particulates or suspended solids are typically removed using a clarifier. Wherever the concentration of suspended solids in raw or wastewater is higher, clarifiers are necessary. Sedimentation tanks in almost all treatment plants. Clarifiers are circular in shape, and occasionally rectangular in shape. The process of sedimentation is the part of water & wastewater treatment where contaminants are settled down due to gravity and the clean liquid or clarified water is separated. The same principle of gravity settling is used by clarifiers in wastewater treatment to remove suspended solids or solid particulates from the liquid. The concentrated impurities are known as sludge whereas those that float to the surface of the liquid are called scum. The large settling tanks with in-built mechanical means like scraper blades act continuously to remove solids towards the pipe or place where sludge and scum collection takes place. The removed sludge will either be recycled as RAS (return-activated sludge) or wasted as WAS (waste-activated sludge). The clarified water is released over overflow weirs on the top of the clarifier which looks very clear.

Frequently Asked Question
The main purpose of a clarifier system is to separate solid particles from liquid, which is often done as part of a larger wastewater treatment process. Clarifiers can be used to separate solids from liquids in various types of wastewater, such as industrial process wastewater, municipal wastewater, and stormwater runoff.
Clarifiers work by using gravity to separate solid particles from liquid. The wastewater is fed into the clarifier and flows through the device, allowing solids to settle to the bottom. The clarified water then flows out the top of the clarifier, while the solids are removed from the bottom by a scraper mechanism.
There are several different types of clarifiers available, including circular clarifiers, rectangular clarifiers, inclined plate clarifiers, and dissolved air flotation (DAF) clarifiers. The specific type of clarifier used will depend on the characteristics of the wastewater and the desired end product.
The by-products of a clarifier system are a combination of clarified water and sludge. The clarified water can be reused or discharged into the environment, while the sludge can be sent for further treatment or disposal.
The advantages of using a clarifier system include improved water quality, reduced sludge volume, and reduced costs associated with handling and disposing of sludge.
There are several signs that can indicate a clarifier system is not working properly, such as an increase in the amount of solids in the clarified water, a decrease in the rate of clarification, or an increase in sludge volume. Regular inspections and maintenance can help to ensure that the clarifier system is operating correctly.
The cost of installing and maintaining a clarifier system will depend on many factors, such as the size of the clarifier, the type of clarifier, and the location of the system. On average, costs can range from tens of thousands of dollars for a small system to several hundred thousand dollars or more for a large, industrial system.
