Methods and Systems for Producing Granules of Biomass in the Treatment of Wastewater

摘要

Methods and systems for the production of granules of biomass in the treatment of wastewater. Organic matter is removed from wastewater in an anaerobic zone and then in an aerobic zone. Waste activated sludge is transferred from the aerobic zone to the anaerobic zone and is used in the formation of granulated biomass in the anaerobic zone. Excess granulated biomass may be removed from the anaerobic zone.
