Enhanced nitrification at short hydraulic retention time using a 3-stage biological aerated filter system incorporating an organic polishing reactor

•An organic polishing reactor was assessed in 3-stage BAF for enhancing nitrification.•The organic polishing reactor contributed to effective NH4-N removal at the short HRT of 1h.•Also, it prevented nitrite accumulation.•It ultimately resulted in the enhanced T-N removal of 3-stage BAF system. In th...
