Membrane Softening Process
Degassification

Raw water contains gases, (i.e.: hydrogen sulfide and carbon dioxide) which are not filtered by the membrane units. Hydrogen sulfide (H₂S) must be removed and treated since it can cause rotten egg odors in and around the plant. After the water is treated using the membrane units it is sent to large tanks in which the water is sprayed through an air stream. This air stream removes about 99% of the H₂S and CO₂, The off gas from this process is further treated in an air scrubber to prevent any escape of the H₂S to the atmosphere, preventing any undesirable odors in the area.

Now that the water has been softened, lets mix them back together.
