Sludge Thickening. The thickening of activated sludge ismon practice many wastewater treatment plants. These plants use a biological treatment process to reduce the wastewater COD and BOD before discharging downstream into the environment. During the process colonies of bacteria develop and grow forming a biological body which produces a

Sludge Thickening Concentration Wastewater Treatment

Jan 06, 2021· The flotation process in sludge thickening is in principle similar to the flotation for pretreatment of wastewater. In the flotation process, air is injected into the sludge tank from the bottom under pressure and a large amount of air bubbles disperse into the sludge, attach themselves to the sludge solids and float them to the surface of the

Sludge Thickeners The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5 from cone bottom clarifiers to 2 4 from the rake bottom clarifiers. The sludge thickener must have sufficient capacity to accumulate and thicken the sludge

4 Step Wastewater Sludge Treatment Process

Apr 03, 2018· The first step in the sewage sludge treatment plan is called thickening. In this step, the sewage sludge is thickened in a gravity thickener to reduce its overall volume, thus enabling the easy handling of the sludge. Dissolved air flotation is another alternative that can be used to effectively to thicken the sludge by using air bubbles to

Fact Sheet: Centrifuge Thickening and Dewatering

Centrifugal thickening and dewatering of sewage sludge is a high speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid to produce a non liquid material referred to as cake. Dewatering wastewater solids reduces the volume of residuals, improves operation, and reduces costs for

Sewage sludge dewatering sludge thickening Decanters

Depending on the size of the waste water treatment plant, different waste water treatment processes are used. Sewage plant operators use Flottweg decanter centrifuges at various stages of waste water treatment to dewater and thicken sewage sludge. Sludge dewatering and thickening reduce the volume of sludge produced. After the sewage sludge is
