Single-Submerged Attached Growth Bioreactor for Simultaneous Removal of Organics and Nitrogen
Publication: Journal of Environmental Engineering
Volume 133, Issue 2
Abstract
The use of a single-unit, single-zone submerged attached growth bioreactor (SAGB) for the combined removal of carbonaceous organics and nitrogen from a municipal wastewater was demonstrated. A nitrification efficiency of 97% was achieved at a total organic loading of . The total nitrogen loading varied from and resulted in effluent total nitrogen concentrations ranging from . Concurrent denitrification was achieved at rates ranging from . This single-unit SAGB, by providing dual treatment capacities, represents a cost-effective option that is particularly attractive for facilities with limited space and budget for system upgrade.
