COD is the most well-liked choice test to BOD for creating the concentration of organic make a difference in wastewater samples.
The permanganate method is comparable but takes advantage of potassium permanganate in place of potassium dichromate. The closed reflux approach requires heating the sample below reflux disorders, which increases the charge on the reaction and allows for a shorter test length.
A COD test can be used to evaluate the incoming influent high-quality so operators can respond to shifting waste load ailments. This assures one of the most successful procedure procedures are getting used to lower prices and to make certain the effluent is within the allow restrictions prior to discharge.
Discharge permits may well stipulate a selected maximum focus for BOD or COD, or simply a % removal. Some vegetation involve accomplishing around ninety% elimination of oxygen demand.
