Home / aerobic stabilized sludge sludge thickener Waste Activated Sludge Processing An input power reduction of approximate ly 70 percent to the fourth stage reactor significantly enhanced the thickening characteristics of the waste activated sludge STABILIZATION A Aerobic digestion of waste activated sludge is an alternative to anaerobic digestion which thermophilic aerobic digestion (or TAD ) This is a similar technique to the one used for composting solid organic waste (see heat treatment used on dewatered sludge – general comments) It capitalises on the exothermic nature of oxidation reactions in order to raise the temperature in the reactor (45 to 60°C); this temperature increase accelerates the reaction Aerobic stabilisation Degremont®07/01/2022 Aerobic digestion is a process of treating the secondary sludge from the biological wastewater treatment process, such as activated sludge and trickling filters; primary sludge is better treated by anaerobic digestion (see Chapter 4) The secondary sludge is primarily insoluble solids such as biomass of microorganisms The objective of aerobic digestion is to Sludge Stabilization Wastewater Treatment Progressive

Digester/Thickener
The stabilized sludge is transferred to the thickener section by gravity on either continuous or intermittent basis In the thickener, sludge compacts by gravity Peripheral drive helical scrapers transport the thickened sludge to a central hopper for withdrawal to final disposal or recirculation Aeration Rotation Thickener Rotation Transfer Air Supernate Thickened Sludge Influent If the sludge treatment line includes their aerobic stabilization, the thickener is generally positioned after this, as this process does not require very high sludge concentrations, not above 225%, for its proper operation Flotation is unsuitable for concentrating biological sludge from secondary clarifier, also called excess or biological sludge The use of centrifugation and TECHNOLOGY FACT SHEETS FOR EFFLUENT TREATMENT PLANTS Membrane thickening aerobic digestion processes produces a Class B stabilized sludge with reliable thickening without using polymers or decanting, allowing wastewater facilities to expand solids storage capacity in existing process tanks and minimize the footprint of newly constructed tanks According to the United States Environmental MEMBRANE THICKENING AEROBIC DIGESTION PROCESSES Bryen
