A membrane process is any method that relies on a membrane barrier to filter or remove particles from water. Fluid is passed through the membrane because of the pressure difference between one side of the membrane and the other. Contaminants remain on one side. Although many types of filter media are used for water treatment — for instance, clay, silt, and sand — one of the properties that distinguish membranes is their ability to separate smaller substances such as salts and ions from a liquid.

These Particles build up over time and can lead to a lack of efficiency in the water filtering/treatment process. Sarentec will come in and regularly check on them for you and replace them if needed.
