The intent is to measure what affect the sample will have on oxygen …
WebJul 12, 2000 · The BOD Test Method* measures the dissolved oxygen consumed in a sample incubated at 20oC for five days. The range of values that can be measured by the test is controlled by the concentration of dissolved oxygen in the sample before incubation and by some minimum measurable final concentration after incubation. The BOD Test … Web10.2.3.1 Dissolved oxygen (DO) DO is the amount of oxygen in aquatic environments that is accessible to fish, invertebrates, and all organism in the water. Most aquatic plants and animals require oxygen to survive; fish, for instance, cannot survive for long in water with dissolved oxygen less than 5 mg/L. The low level of dissolved oxygen in ...
WebBIOCHEMICAL OXYGEN DEMAND (BOD) Section 1: GENERAL. In the presence of free oxygen, aerobic bacteria use the organic matter found in wastewater as “food”. The BOD test is an estimate of the “food” available in the sample. The more “food” present in the waste, the more Dissolved Oxygen (DO) will be required.
