aerobic stabilized sludge sludge thickener

TECHNOLOGY FACT SHEETS FOR EFFLUENT TREATMENT PLANTS

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 2-2.5%, for its proper operation. Flotation is unsuitable for concentrating biological sludge from secondary clarifier, also called excess or biological

Aerobic stabilisation - Degremont®

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 and, if sufficient, will ...

Sludge Thickening - Degremont®

Extremely dilute sludge delivered by the water line (usually 99 to 99.8% water)is concentrated to produce sludge containing 90 to 96% water. This sludge is still fluid and, therefore, can be pumped out. Thickening constitutes an additional investment cost and a source of possible nuisances.

Sludge Stabilization - Wastewater Treatment -

Sludge aerobic digestion. 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.
