Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume.

The sludge thickening is a process used to increase the solid content in the sludge by separating and remaining the liquids. The gravity thickening makes the use of the force of gravity, as the main agent in thickening process of sludge. A)The gravity thickening process-It is accomplished in a tank like the conventional sedimentation tank.

Description. Sludge Thickeners is the practice of increasing the solids content of sludge by the removal of a portion of its liquid content. A modest increase in solids content can decrease total sludge volume significantly, entailing reduced size requirements for subsequent sewage treatment units. Sludge thickening methods are usually physical in nature flotation and gravity belts.
