Due to the previously mentioned, it is necessary to test the various different techniques, at the least for COD and BOD, in various areas such as Expense–gain, validation, efficacy and sensitivity with the goal of proposing one particular instead with the reference methods.
To evaluate COD, the water sample is put in the shut container read more and subjected to some powerful oxidant, such as potassium dichromate and sulfuric acid, for the specified duration and temperature.
The COD is the amount of oxygen required by the two the inorganic and natural and organic components on the wastewater sample.
