Abstract
A semi-permeable membrane based purification system expresses permeate through a membrane, and uses an air lift pump to raise the permeate. In particularly preferred embodiments, a plurality of membranes are positioned at least several hundred feet below the surface of the each, and are used to desalinate salty or brackish water. Ozone may be used to further purify the water and help maintain the integrity of the membranes.
