Degassing is the process by which gases dissolved in water are removed. In order to choose the correct treatment, it must be taken into account that there are gases that dissolve in water, such as CO2, which forms calcium carbonate, and nitrogen or oxygen that do not ionize with water, exerting a gas pressure on it.
Degassing can be performed by applying an atmospheric, thermal, or chemical process.
It can also be done through the use of hydrophobic membranes that eliminate the use of chemicals.
And so, we distinguish among the following types:
