Sludge Thickening - an overview ScienceDirect Topics

The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener required. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment.

Sludge Thickening - an overview ScienceDirect Topics

Gravity thickening works on the simple principle of the force of gravity being greater on denser materials. Sludge from the clarifiers is fed from a center well to the tank, and gravity then separates the solids, which settle downward and compact at the bottom of the tank.

HUBER Solutions for Sludge Thickening - Huber

Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and digested sludge can be better gravity-thickened than secondary sludge. Secondary sludge (e.g. waste activated sludge) is preferably thickened mechanically, separate from primary sludge.

Sludge Thickening - Sewage Treatment - Reverse Osmosis ...

Wastewater treatment plants commonly use thickening devices to increase the solids concentration at the end of a particular process step within the activated sludge process. Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes such as digestion and dewatering.

13-08-2019  Sludge thickening dewatering process of various sludge types. published date: 08-13-2019. STP typically requires sludge dewatering prior to final disposal of sludge/biosolids, or as a prelude to further processing or stabilization. Since the dewatering process has significant differences in reducing the moisture content of the sludge, the final sludge treatment method usually has a significant ...

Sludge Thickening - Degremont®

Extremely dilute sludge delivered by the water line (usually 99 to 99.8% water)is concentrated to produce sludge containing 90 to 96% water. This sludge is still fluid and, therefore, can be pumped out. Thickening constitutes an additional investment cost and a source of possible nuisances.
