WebThe development of a rapid sensor for Biochemical Oxygen Demand (BOD) is important for rapid determination of the degree of pollution in river water. A short–term BOD … Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time … See more 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 … See more The BOD is used in measuring waste loadings to treatment plants and in evaluating the BOD-removal efficiency of such treatment systems. See more Biosensor An alternative to measure BOD is the development of biosensors, which are devices for the … See more The development of an analytical instrument that utilizes the reduction-oxidation (redox) chemistry of oxygen in the presence of dissimilar metal electrodes was introduced during the 1950s. This redox electrode (also known as dissolved oxygen sensor ) … See more The Royal Commission on River Pollution, established in 1865, and the formation of the Royal Commission on Sewage Disposal in 1898 led to the selection in 1908 of BOD5 as the definitive test for organic pollution of rivers. Five days was chosen as an … See more Winkler published the methodology of a simple, accurate and direct dissolved oxygen analytical procedure in 1888,. Since that time, the analysis of dissolved oxygen levels for water has been key to the determination of surface water. The Winkler method is … See more The test method involves variables limiting reproducibility. Tests normally show observations varying plus or minus ten to twenty percent around the mean.
