Simultaneous COD, Nitrogen and Phosphate Removal in an Aerobic Granular Sludge Membrane Bioreactor

Open publisher page 2 citations

Abstract

A submerged membrane bioreactor (MBR) combined with aerobic granular sludge (AGS) was studied in this research, in order to enhance removal performance containing higher concentration of organic solids, nitrogen and phosphorus than conventional biological phosphorus removal process. Aerobic granular sludge technology offered a possibility of simultaneous COD, nitrogen and phosphate removal in one reactor. In this aerobic granular sludge membrane bioreactor (AGSBR) process, high average removal efficiencies were obtained: 100% COD removal, 98% phosphate removal and 100% ammonium removal. Moreover, analysis of typical cycle showed simultaneous nutrient removal was possible and phosphorus removal occurred partly by (biologically induced) precipitation. Monitoring the laboratory scale reactors for a long period showed that ORP, pH and DO can be good indication parameters.
