A COD test measures all of the chemicals in a sample which can be oxidized. A BOD5 test measures the total amount of food (or organic carbons) that bacteria can oxidize (in 5 days).
A COD test result (that can be performed in about 2 hours) can be correlated to an expected BOD5 result (which takes 5 days).

no it is not
It's for if you don't have any points in the game than you use those example: I have only 200 points but the mystery box is 950 than you use cod points to buy the box
COD 2
there we go all of the cod names1=cod 12=cod 23=cod 34= Modern Warfare5= World at War6= Modern Warfare 27=black ops
COD 4: Modern Warfare COD 5: World At War COD 6: Modern Warfare II COD 7: Black Ops COD 8: Modern Warfare III COD 9: Iron Wolf And something about a Future Warfare, not sure bout that one. :)
Type your answer here... It's not. Typically, COD is greater than BOD. The COD test is used primarily as an operational control because it takes only a matter of hours, compared to 5 days for the BOD test.
COD=100 What is Bod
BOD is inversely proportional to COD
No, not increasing because it is not reducing oxygen.But it can alter the measured BOD and COD rather unpredictable possibly by decreasing BOD and in- or de-creasing COD
0.7 kg of BOD and 1.4 kg of COD
COD is usually greater than BOD5 as it measures the oxidation of all organics, not just the biodegradable ones

"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..
1. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized BOD- Biochemical Oxygen Demand is supposed to measure the amount of food (or organic carbons) that bacteria can oxidize. 2. COD is usually measured and the test is simple and easy to perform with the right equipment and can be done in 2 hours. BOD usually takes 5 days 3. Permissible limit of COD =250 to 500 ppm Permissible limit for BOD = 30 mg/L
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.
