This incorporates a immediate effect on aeration tools power intake. Possessing an knowledge of COD trends lets engineers to enhance power use and attain Charge of Electrical power charges.
COD is usually used as an estimator of Organic oxygen demand (BOD) as the test is far less complicated and much more robust. In properly-understood programs, the ratio of BOD to COD website is proven, and it is fairly straightforward to extrapolate a BOD concentration from the COD test.
You will find there's correlation among COD and BOD, nonetheless, it should be experimentally proven ahead of applying 1 parameter to precise Yet another. Commonly COD Examination (that's a considerably faster and much more accurate strategy) is utilized to estimate BOD utilizing the founded correlation.
Color: The color of drinking check here water that's small in oxygen may perhaps alter from mild inexperienced to pea-soup green, brown, grey or black. Dim sediments due to metallic sulfides suggest anoxic circumstances.
