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 ).

WebBardenpho process, by contrast, does not have the first anoxic zone. These two process options achieve the same TN removals as the MLE process, but also provide phosphorus removal, usually down to an effluent in the range of 0.5-1.0 mg/L TP. Other similar flow sheets exist with different names (e.g., UCT, AO2). A post-anoxic zone can be added ...

WebMay 11, 2010 · The treatment system, also known as a 4-Stage Bardenpho process, was operated with an external recycle ratio of 3:1 and an internal recycle ratio of 4:1. The first anoxic reactor actual hydraulic retention time was 1.5 hours, while the first aerobic retention time was 3 hours. The very high ammonia concentration was simulated by pumping ...
