WebbQuestion: In a wastewater treatment plant with a conventional activated sludge system, sludge with 0.8% solids content from the final settling basin is thickened to 3.2% solids content in a gravity thickener. Please give information about the water types contained in the thickened sludge and the new percentages of these water types. 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. something in my eye but can\u0027t find it

WebbTreatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes. Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener.
