Five-stage bardenpho process

WebWhat is a 5 stage Bardenpho process? The five-stage Bardenpho process detailed (WAS = waste-activated sludge; RAS = return-activated sludge). The five zones — anaerobic, anoxic, aerobic, anoxic, and aerobic — each require dedicated tank space, which is the critical component and cost of the Bardenpho process. WebJan 1, 2024 · 5-Stage Bardenpho process To improve the rates of nitrogen and phosphorus removal in the A2/O process, the Bardenpho process was developed by adding an anaerobic tank and an aerobic tank at the end of the A2/O process (anaerobic–anoxic–aerobic–anoxic–aerobic) ( Rabinowitz, 1980 ) ( Fig. 5.3A ).
