Thickening table ME - Estruagua
2021-4-6 Thickening table ME can be used to achieve final stage and increase the concentration of dry matter of sludge up to max. 8%, replacing static gravity thickeners or flotation systems. It serves as a preliminary stage for dehydrating by pressing, if combined in line with a band filter, in order to optimize its performance and efficiency.

Sludge Thickening Concentration - Wastewater Treatment
2021-5-19 The thickened sludge is withdrawn from the bottom of the tank and pumped to the digesters or dewatering equipment. Gravity thickening can be achieved in a separate tank or within the clarifier, if it is so designed. Thickening within the clarifier is achieved at the lowest part of the clarifier within a sludge

Sludge treatment − rotary drum thickening Sludge Processing
2020-6-18 A rotary drum thickener (RDT) is based on the same principle as a gravity belt thickener (GBT), in that water drains from the sludge through a retaining porous medium. For an RDT the porous medium is the cylindrical wall of a 0.5−1.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge

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 will be. 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.
