Abstract
Systems and methods for the desalination of seawater and the purification of surface and groundwater are provided. The systems utilize the hydrostatic pressure of a natural or induced water column to filter water through a reverse osmosis, nanofiltration or other membrane, whereby a certain desired water quality or potable water is obtained.
Claims7
A water treatment system, comprising:
- a shaft configured to be submerged to a depth extending down into the earth and flooded with water to be treated, the water having a first pressure at the submerged depth;
- an inflow tube disposed within the shaft;
- at least one membrane disposed with the inflow tube, the membrane having a concentrate side and a permeate side;
- a plurality of guides aligned with a vertical length of the shaft;
- a collector in fluid communication with the permeate side of the membrane;
- and
- a passageway configured to expose an interior of the collector to a second pressure which is lower than the first pressure, wherein exposing the concentrate side of the membrane to the first pressure drives a filtration process in which permeate moves across the membrane from the concentrate side to the permeate side.
