Simultaneous nitrification-denitrification and phosphorus removal in a fixed bed sequencing batch reactor (FBSBR)

▶ Sludge production in FSBR reactor is 20-30% less than SBR reactor. ▶ FSBR reactor showed more nutrient removal rate than SBR reactor. ▶ FSBR reactor showed less VSS/TSS ratio than SBR reactor.
