CHAPTER 3 SLUDGE THICKENING - Marmara

SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is ...

Alfa Laval - Orege SLG

Pre-treating sludge with an Orege SLG system immediately before processing it through the Alfa Laval AS-H belt filter press or gravity belt thickener can improve final sludge dryness by 2% or more (depending on process conditions). This can significantly reduce sludge management costs, frequently a major expense for a wastewater treatment plant. When you add up polymer, hauling, and operating ...

Sludge treatment − centrifugal thickening | Sludge Processing

Centrifugal thickening increases the sludge concentration (i.e. thickens the sludge) by encouraging the particles to migrate to the walls of a rapidly rotating cylindrical vessel under the influence of a centrifugal force. There are a number of configurations of centrifuge used for reducing the water content of sludge.
