Bod exerted meaning
WebSep 12, 2024 · BOD technically stands for Biological Oxygen Demand BOD5 means the test has been run for 5 days. C-BOD means only the Carbonaceous Biochemical Oxygen … WebBOD sample over a 5-day period. This time period was established years ago in England and resulted from the fact that it required 5 days for water in most streams to reach the ocean. The microorganisms continue to exert an oxygen demand on the stream after this time and the ultimate BOD can be determined by conducting the experiment over a 20-
