What is BOD | Characteristics of BOD | Advantages and Disadvantages of BOD | Importance of BOD.

What is BOD? BOD Test BOD stands for Biological Oxygen Demand (BOD). BOD is a measure of the amount of oxygen required by microorganisms to biologically decompose organic matter in water. It is an important indicator of the quality of water and the pollution level of water bodies. BOD measurement is used to assess the extent of organic pollution in natural water systems, including rivers, lakes, and oceans. The characteristics of BOD include the following: Biochemical Oxygen Demand 1. BOD is a measure of the amount of oxygen that is required for the biological decomposition of organic matter in water. 2. The higher the BOD level, the greater the amount of organic matter present in the water. High levels of BOD indicate that there is an excess of organic material that is causing water pollution. 3. BOD can be used to determine the level of treatment required to clean up wastewater. Higher levels of BOD mean that more treatment is required to remove pollutants from the water. 4. BO
