Biochemical oxygen need (BOD) is the quantity of oxygen essential for microbes to execute the biological decomposition of the dissolved solids or perhaps the organic and natural substance within the sewage underneath the aerobic ailments at a offered temperature.
Dependency on microbial exercise: The accuracy of BOD measurements is reliant on the activity of website microorganisms existing inside the sample. Elements for instance nutrient availability and microbial wellness can influence the dependability of the test success.
BOD is a very elaborate test; having said that, dependable and dependable BOD effects could be produced by any lab if analysts: use fantastic laboratory QC practices;
Contamination: Contamination from exterior sources all through sample assortment, dealing with, or Investigation can introduce supplemental organic make a difference or microorganisms, resulting in artificially elevated BOD test values.
