The “cod” image will flash for 3 seconds, then the sample test final result will show up from the Screen as aspect for each million COD. Record the test result.
The dichromate approach can be a extensively employed technique for measuring COD. It entails adding a acknowledged surplus of potassium dichromate to your regarded volume of sample within the existence of sulfuric acid.
Sample Matrix Compatibility: The thermal oxidation technique is applicable to your wide array of h2o sample matrices, which includes drinking drinking water, wastewater, surface water, and industrial course of action water.
BOD could possibly be outlined as the quantity of oxygen used for biochemical oxidation by microorganisms within a device quantity of drinking water. The test has become created for 5 times at 20oC.
COD is Utilized in wastewater remedy to measure the level of natural and organic pollutants in wastewater. It is a vital parameter in the design and Procedure of procedure crops, as it provides an estimate of the level of oxygen that may be needed to oxidize the natural and organic make any difference in the wastewater.
