Lesson 6: Sedimentation

Sludge accumulates at the bottom of the tank/basin. Typical tanks or basins used in sedimentation include conventional rectangular basin, conventional center-feed basins, peripheral-feed basin, and spiral-flow basins. In conventional treatment plants, the amount of detention time required for settling can vary from 2 to 6 hours.

Types of Sedimentation Tanks used in Water Treatment

Dec 04, 2016  A sedimentation tank is structure in which wastewater is filled and stored for some time to remove the suspended particles present in the water. These particles may settle at the bottom of the tank and are removed by using scrapers. If the suspended particles have low specific gravity than water, they settle at the top of the tank.

Sedimendation - Water Treatment Process Plant Design

Sedimentation is a unit operation to settle out the suspended particles and flocs in water. Sedimentation water treatment is achieved by lowering the velocity of the water below the suspension velocity to settle out suspended particles by gravity. The process is also known as settling or clarification. Most water treatment plants include ...

How Wastewater Treatment WorksThe Basics

another sedimentation tank to remove excess bacteria. The trend today is towards the use of the activated sludge process instead of trickling filters. The activated sludge process speeds up the work of the bacteria by bringing air and sludge heavily laden with bacteria into close contact with sewage. After the sewage leaves the settling tank in the

The basin outlet zone (or launder) should provide a smooth transition from the sedimentation zone to the outlet from the tank. This area of the tank also controls the depth of water in the basin. Weirs set at the end of the tank control the overflow rate and prevent the solids from rising to the weirs and leaving the tank before they settle out.
