Web5 data, and a BOD 5/CBOD 5 conversion factor cannot accurately predict CBOD 5 values for STE. Since the term FOG has now been replaced by the term oil and grease (O&G), O&G should be used for characterizing STE as well. Suggested single-sample residential STE threshold values include: BOD 5 <220 mg/L, TSS <100 mg/L, O&G < 30 Weban oxygen demand or toxins. When incubated for 5 days at 20 °C, the dissolved oxygen concentration in the dilution water must not change by more than 0.2 mg/L. Carbonaceous BOD (CBOD) can be determined by the addition of nitrification inhibitor. A test for CBOD is recommended for

Most natural waters contain small quantities of organic compounds. Aquatic microorganisms have evolved to use some of these compounds as food. Microorganisms living in oxygenated waters use dissolved oxygen to oxidatively degrade the organic compounds, releasing energy which is used for growth and reproduction. Populations of these microorganisms tend to increase in proport… WebSep 12, 2024 · September 12, 2024 by Alexander Johnson. BOD occurs in 2 general stages. While calculating the oxygen demand, the carbonaceous stage is taken into account. This stage is almost completed in 5 days, which means that most of the organic content of the sewage is oxidized under aerobic conditions in 5 days. Hence ,BOD for 5 …
