WebFeb 1, 2003 · Based on the theory of sedimentation-consolidation, Cettem Ltd. developed the software SimEspc which gives as result the thickening Unit Area UA, that is, the … WebJun 16, 2024 · In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.
Sludge treatment − gravity thickening Sludge Processing
WebA design developed in the UK by the WRc ( Warden, 1983), for waterworks sludge thickening applications, consists of a cylindrical tank of water depth 2–3.5 m with a shallow sloping floor (1 in 20). Sludge is introduced at a central feed well and the supernatant overflows a peripheral weir. WebHigh rate thickener units are provided in sizes ranging from 5' to 250' in diameter, and can accommodate drive head torques of up to 4 million foot pounds. They are available in shaft or cage driven models. Shaft drive thickeners can be truss or beam supported for heavy duty applications. trench box uk
