Updated On: Jul 9, 2024
- At any instant the deoxygenation rate is directly proportional to the amount of oxidizable organic material present.
- At any instant the deoxygenation rate is inversely proportional to the amount of oxidizable organic material present.
- The reoxygenation rate is directly proportional to the dissolved oxygen deficit.
- The reoxygenation rate and deoxygenation rate are directly proportional to the saturation concentration of dissolved oxygen.
