Sludge treatment − gravity belt thickening | Sludge …

2020-6-18 · How gravity belt thickening works. Gravity belt thickening (GBT) increases the sludge solids concentration (i.e. thickens the sludge) by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a moving belt) on which the sludge sits.. There are two types of belt-based processes for increasing sludge solids concentration.

CHAPTER 3 SLUDGE THICKENING

2012-3-22 · Location of the thickener in a wastewater treatment plant is important. If sludge is to be digested, thickening a blend of primary and waste activated sludge is a good practice. If these sludges are to be dewatered, then they should be thickened separately and mixed immediately before dewatering [3]. Sludge Thickening vs. Dewatering
