Glass BOD bottle This conventional method is regarded by EPA, which happens to be labeled Method 5210B from the Regular Approaches with the Evaluation of Water and Wastewater.[twelve] As a way to attain BOD5, dissolved oxygen (DO) concentrations inside a sample has to be measured prior to and after the incubation time period, and properly adjusted because of the sample corresponding dilution component. This Evaluation is performed using 300 mL incubation bottles through which buffered dilution drinking water is dosed with seed microorganisms and stored for five days at the hours of darkness home at 20 °C to prevent DO manufacturing through photosynthesis. The bottles have traditionally been manufactured from glass, which required cleansing and rinsing involving samples. A SM 5210B approved, disposable, plastic BOD bottle is available which eliminates this phase.
