The ratio of oxygen available to the oxygen required for stabilisation...
Relative Stability
The ratio of oxygen available to the oxygen required for the stabilisation of sewage is known as the relative stability of the sewage. This parameter is crucial in determining the health of a water body and its ability to support aquatic life.
Importance
The relative stability of sewage is essential to understand as it indicates the level of oxygen needed by bacteria to break down organic matter in the water. If the oxygen available is less than what is required for stabilisation, it can lead to oxygen depletion in the water, resulting in the death of aquatic organisms.
Calculation
The relative stability is calculated by comparing the biological oxygen demand (BOD) of the sewage to the available oxygen levels. If the BOD is higher than the available oxygen, the sewage is considered unstable and can lead to pollution of the water body.
Monitoring
Monitoring the relative stability of sewage is crucial in wastewater treatment plants to ensure that the oxygen levels are sufficient for the bacteria to decompose organic matter effectively. Regular testing of BOD and oxygen levels helps in maintaining the stability of sewage and preventing environmental degradation.
In conclusion, understanding the concept of relative stability and monitoring it in sewage treatment processes is essential for maintaining the health of water bodies and protecting the environment.
