WebAug 27, 2024 · Ultimate BOD values and appropriate kinetic descriptions are needed in water-quality modeling studies [e.g., UBOD:BOD 5 ratios for relating stream assimilative capacity to regulatory requirements; definition of river, estuary, or lake deoxygenation kinetics; and instream ultimate carbonaceous BOD (UCBOD) values for model calibration]. WebApr 2, 2024 · Why BOD test needs 5 days incubation period – This is because in 5 days duration 70 – 80% of organic matter gets oxidized. Another reason to take it as standard is to avoid the interference of nitrification of bacteria as this starts after 6th or 7th day. Therefore, by avoiding nitrification we get only “CARBONACEOUS BOD”.
