ABSTRACT:
A process is described for the operation of a multiple zone batch treatment system for biological or biophysical treatment of wastewater. The system comprises two or more batch treatment zones with wastewater passing sequentially through all treatment zones. After the mix and settle batch steps occur for all zones, influent wastewater flows into the first zone and displaces clarified wastewater in a plug flow mode through each treatment zone and ultimately from the last zone. The combining of the decant and fill steps for all or most of the zones provides for shorter cycle times and greater capacity for the system.
