Biochemical oxygen demand bod คือ
WebSep 15, 2014 · Conducting the Test. BOD is determined by analyzing the difference in dissolved oxygen from a sample for five days. Because of this standardized time, BOD is often referred to as BOD-5. The dissolved oxygen readings are usually in parts per million (ppm). Higher BOD indicates more oxygen is required, which is less for oxygen … WebThe test for biochemical oxygen demand (BOD) is a bioassay procedure that measures the oxygen consumed by bacteria from the decomposition of organic matter (Sawyer …

WebBiochemical oxygen demand (BOD) represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions at a specified temperature. BOD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving water. BOD is used as a … WebBiochemical Oxygen Demand (BOD), representing the biodegradable organic load in water, is a prime parameter to assess water quality. Estimation of biochemical oxygen demand requires prolonged incubation of water samples. Thus, it is a time-consuming as well as energy-consuming process. Therefore, it is not possible to respond rapidly for ...
WebMar 6, 2012 · Figure 5.8. Titrating a DO sample using a buret. Select a sample volume and sodium thiosulfate titration cartridge for the digital titrator corresponding to the expected dissolved oxygen concentration according to Table 5.4. In most cases, you will use the 0.2 N cartridge and the 100-mL sample volume. WebDissolved oxygen (DO) is measured at the beginning of the analysis and after a 5 day, in-the-dark, 20 'C incubation period. The difference of the DO between the beginning and end of analysis is used to calculate the BOD. The BOD test is a bioassay. Bioassay is a shorthand form, commonly used term for biological assay and is a type of in vitro ...
