Wastewater quality indicators - Wikipedia

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. The BOD test measures the oxygen demand of biodegradable pollutants whereas the ,COD, test measures the oxygen demand of biodegradable pollutants plus the oxygen demand of non-biodegradable oxidizable pollutants.

Solutions for the treatment of wastewater with refractory COD

Refractory COD treatment. As indicated, refractory COD inhibits biological treatment in effluents, and the treatment techniques used to remove these contaminants are wet oxidation and thermal oxidation (incineration). The main types of wet oxidation technologies are: Supercritical water oxidation (SCWO) Non-catalytic wet air oxidation (WAO)
