Biological Oxygen Demand BOD Testing
Biological Oxygen Demand (BOD): A Complete Laboratory Guide Biological Oxygen Demand (BOD) is one of the most widely used parameters for evaluating organic pollution in water and wastewater. It reflects the amount of oxygen required by microorganisms to biologically decompose organic matter under aerobic conditions. This blog presents a clear, original, and laboratory-oriented explanation of the BOD test procedure , including reagent preparation, dilution techniques, incubation, and calculation Purpose of BOD Analysis The purpose of this procedure is to describe the laboratory method for measuring Biological Oxygen Demand (BOD) in water and wastewater samples. Scope This method is applicable to environmental laboratories involved in the analysis of: Surface water Groundwater Treated and untreated wastewater Industrial effluents where BOD determination is required for monitoring, treatment efficiency, or regulatory compliance.
