WebCOD is oxygen demand for oxidation of organic and non biodegradable organic matter. COD is always greater than BOD hence the ratio will be always greater than 1. If BOD/COD is 0.92 to 1, waste water is fully biodegradable. If BOD/COD > 0.63, difficult to biodegardable. BOD can be reduced to the permissible level but COD cannot be reduced easily ...

Most natural waters contain small quantities of organic compounds. Aquatic microorganisms have evolved to use some of these compounds as food. Microorganisms living in oxygenated waters use dissolved oxygen to oxidatively degrade the organic compounds, releasing energy which is used for growth and reproduction. Populations of these microorganisms tend to increase in proport… WebMay 28, 2014 · One of the biggest complaints of the BOD test is blank depletion. According to Standard Methods for the Examination of Water and Wastewater (21st edition), “The DO uptake in 5 d must not be more that 0.20 mg/L and preferably not more than 0.10 mg/L.”.
