Aerobic decomposition of sewage

Aerobic decomposition of sewage is a process where organic matter is broken down by microorganisms in the presence of oxygen. This process leads to the evolution of gases.

Gases evolved during aerobic decomposition of sewage

The gases evolved during aerobic decomposition of sewage are:

1. Carbon dioxide (CO2) - This gas is produced by the microorganisms as they break down organic matter.

2. Ammonia (NH3) - This gas is produced when nitrogen-containing compounds in the sewage are broken down by microorganisms.

3. Sulfur dioxide (SO2) - This gas is produced when sulfur-containing compounds in the sewage are broken down by microorganisms.

Importance of gases evolved during aerobic decomposition of sewage

The gases evolved during aerobic decomposition of sewage are important because they can have an impact on the environment and human health. For example:

1. Carbon dioxide - This gas is a greenhouse gas, which means that it contributes to global warming.

2. Ammonia - This gas can be toxic to fish and other aquatic life if it is released into waterways.

3. Sulfur dioxide - This gas can cause respiratory problems in humans and can contribute to acid rain.

Conclusion

In conclusion, the gases evolved during aerobic decomposition of sewage are carbon dioxide, ammonia, and sulfur dioxide. These gases are important because they can have an impact on the environment and human health.
