Official WHO Definition

In an activated sludge process settled wastewater is contacted with recirculated activated sludge in an aerated chamber. In this way a substantial amount of micro-organisms is kept in the treatment process to consume the organic materials in the wastewater. Excess sludge is removed after sedimenting the aerated mixture (UNEP 2000).
