Conventional Activated Sludge

Document ID: 

Activated sludge refers to suspended aerobic sludge consisting of flocs of active bacteria, which are responsible for consuming and removing aerobically biodegradable organic substances from wastewater. For as long as the pollutants are biodegradable, activated sludge systems are capable of handling blackwater, greywater, fecal sludge, and industrial wastewater. Activated sludge reactors are aerobic suspended growth-type processes, which utilize large amounts of injected oxygen to maintain aerobic conditions and cultivate the growth of active microorganisms responsible for removing organic substances from wastewater. Types of suspended-growth activated sludge systems are oxidation ditches, deep shafts, and sequencing batch reactors (SBRs).
