BOD test bottles at the laboratory of a wastewater treatment plant.

Potassium permanganate's effectiveness at oxidizing organic compounds varied widely, and in many cases, biochemical oxygen demand (BOD) measurements were often much greater than results from COD measurements. This indicated that potassium ...
Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant. Both have been widely adopted as a measure of pollution effect. Any oxidizable material present in an aerobic natural waterway or in an industrial wastewater will be oxidized both by biochemical (bacterial) or chemical processes.
