Biochemical oxygen demand rpd
WebCarbonaceous biochemical oxygen demand (CBOD) is the result of the breakdown of organic molecules such a cellulose and sugars into carbon dioxide and water. Nitrogenous oxygen demand is the result of the breakdown of proteins. Proteins contain sugars linked to nitrogen. After the nitrogen is "broken off" a sugar molecule, it is usually in the ... WebJan 15, 2010 · The biochemical oxygen demand (BOD) test is one widely applied method to quantify the consumption of oxygen in the water column from the decay of organic matter (carbonaceous BOD, or CBOD) and nitrification of ammonia (nitrogenous BOD, or NBOD). ...
