Webb1 nov. 2024 · BOD5 is also called soluble BOD. This means that BOD5 represents oxygen demand by most common wastewater components such as sugars, fatty acids, starches, etc. What remains in the BOD5 bottle after 5 days tends to be insoluble or recalcitrant organic compounds. WebbThus, the theoretical oxygen demand would then be: Oxygen demand = (Gram of oxygen used) / (Gram of carbon oxidized) = 192 / 72 = 2.67 g/g of carbon The actual BOD will be less than theoretical oxygen demanddue to incorporation of some of the carbon into newly synthesized bacterial cells.
