WebMay 18, 2024 · In aeration tank biological culture is developed. At this stage, the primary treated effluent is exposed to biological culture, which degrades organic matter present in effluent and reduces COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) from the effluent. WebMeasurements of oxygen consumed in a 5-d test period (5-d BOD or BOD 5, Section 5210B), oxygen consumed after 60 to 90 d of incubation (ultimate BOD or UBOD, Section 5210C), and continuous oxygen uptake (respirometric method, Section 5210D) are described here. Many other variations of oxygen demand measurements exist, …
