The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
Chemical Oxygen Demand (COD) is a labortory test to give a measure of the amount of reactive organic materials in a sample of water. Like the five day Biochemical Oxygen Demand (BOD5) it demonstrates the amount of organics present by how much oxygen they consume over a period of carefully controlled conditions (the starting and ending oxidant concentrations are measured and the temperature is controlled)
The chemical oxygen demand (COD) of drinking water is typically low, ranging from 1 to 5 mg/L. This value indicates the amount of oxygen required to oxidize organic and inorganic matter present in the water. High COD levels in drinking water can indicate contamination and the presence of pollutants.
The chemical symbol for the element oxygen is O.
If you mean Carbon minus Oxygen then, no. It isn't an equation.
I'm assuming you mean water; which is H2O (2 hydrogen and 1 oxygen atom)
There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.

COD = Chemical Oxygen Demand
"COD" is Chemical Oxygen Demand," and BOD is Biochemical Oxygen Demand." These are the two processes that cause oxidation of an object in either a natural waterway or in industrial wastewater..
Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .
if you mean what is the chemical with the symbol O it is oxygen if not i don't know
Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) both measure the quantity of organic compounds found in water. The makes them significant when is comes to the treatment of water.
O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)

Well, dissolved oxygen impacts water quality because if the level of the dissolved oxygen is too low then organisms can die. _________________________________________________________________ That is okay, but I want to what dissolved oxygen tests for. ------ For the water quality are tested: - total oxygen demand (TOD) - biochemical oxygen demand (BOD) - chemical oxygen demand (COD) - sometimes, carbonaceous biochemical oxygen demand (CBOD) For details about the analytical procedures I recommend you to read a book or a collection of analytical methods for water, searching in a library or searching on the Internet.
Some of the chemical companies offer biochemical oxygen on demand would be the Myron L Company, Mantech, Environmental Services by Daniel L. Theobald, Ovivo, Westech Engineering, and Cleveland Biotech Ltd.
The calculated amount of oxygen required to oxidized a compound to its final oxidation products . The organic matter of sewage is mainly composed of carbohydrats , protein, fats,and products of their decomposition . If the chemical formulaeof the organic matter are called as theoretical oxygen demand can be calculatd.
