Abstract (en)
[origin: WO2006023094A1] A variable process and system (10) for treating wastewater. Wastewater flows into a first operational area (50) where solids separate from liquid. Wastewater is transferred to a second operational area (102). At a predetermined transfer time upon a condition precedent having been satisfied, wastewater is transferred to a third operational area (180). The batch of wastewater is treated aerobically. The batch of treated wastewater is then dispersed.
