Biogas is achieved from the waste products, and by further upgrading, it strengthens to serve as 100% replacement for natural gas. There has been an increasing demand for upgraded biogas, as it helps in reducing the need for fossil fuels that are depleting. Thus, it has become increasingly attractive to upgrade biogas for the need of natural gas quality and inject it into the natural gas grid or utilize it as a transport fuel. There are various biogas upgrading technologies, ranging from highly sophisticate cryogenic techniques to the most generally utilized water scrubbing.

Water treatment aerators are used to remove impurities, particles, and dissolved gases such as carbon dioxide from the water and oxidize dissolved metals such as volatile organic chemicals, hydrogen sulfide, and iron.
