The PowerDrum (PDR) is considered to be an easy and efficient thickening solution prior to the dewatering process and can deal with biological sludge throughputs ranging from 15 to 180 m3/hr.H6 summary wastewater Sludge treatment Thickening,01-07-2021· 6. Sludge treatment Thickening (5.1) Sludge composition: Thickening is important for het subsequent sludge treatments steps (digestion and dewatering) but also for transportation of liquid sludge to a central point. Different implementations of thickening: Gravitational thickening: Diameter is about 5 to 25 m, sidewater depth is 3-5 m.🚧 Sludge treatment − rotary drum thickening | Sludge,,18-06-2020· How rotary drum thickening works. Rotary drum thickening increases the sludge solids concentration (i.e. thickens the sludge) by agitating the solids in a slowly-rotating vessel with porous walls though which the water (or filtrate) drains.. 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,CHAPTER 12 Sludge Processing and Disposal,12.3.2.3 Continuous Thickening Variable-speed sludge draw-off pumps may be provided so that thickening can be continuous, or an adjustable on-off time clock control for pulse withdrawal may be used with constant-speed pumps to improve control over the thickening. 12.3.2…sludge thickener design criteria for sewerage,SLUDGE THICKENING FS-FNG-001 Page. 3 of 31 2.- GRAVITY THICKENING 2.1.- General description of the unit The gravity thickening design is similar to a clarifier.
