It is a batch-fed, batch-decanted, suspended growth system and is operated in a cyclic sequence of four stages: feed, react, settle and decant (Wirtz and Dague, 1996). It comprises a single tank in which all events take place, and since a significant part of the cycle-time is spent settling the biomass from the treated wastewater, the reactor volume requirement is higher than for continuous flow processes.
