Sludge thickening in wastewater treatment
WebbDESCRIPTION The sequencing batch reactor (SBR) is a fill-and- draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged. Equali zation, aeration, and clarification can all be achieved using a single batch reactor. Webb27 okt. 2014 · Thickening is a fundamental stage of sludge pretreatment. Pre-dewatering technologies include rotary sludge thickeners, gravity thickeners, dissolved air floatation clarifiers and belt presses. The most widespread thickening method is gravity thickening.
