Stabilization Of Thickened-Activated Sludge Through The Anoxic-Aerobic Digestion Process

Aerobic digestion is widely used to treat waste-activated sludge and thickened sludge from wastewater treatment plant due to its shorter retention time and achieving the same efficiency in solids volume reduction compared to anaerobic digestion. However, the supernatant and filtrate from the aero...
