WebApr 1, 2024 · A traditional Orbal oxidation ditch system with disk aerators in a sewage treatment plant in Xi’an, China, was used for this work. The design capacity was 100,000 m 3 /d, and four parallel systems each with an anaerobic tank were in operation (Fig. 1 a). The HRT of the Orbal oxidation ditch was 17.5 h and the effective depth was 4.2 m. WebOrbal Processes Julie L. Zilles, Jordan Peccia, Daniel R. Noguera ABSTRACT: The traditional process for enhanced biological phos phorus removal (EBPR) in wastewater treatment involves an anaerobic zone followed by an aerobic zone.
