Abstract
A system and method for producing potable water from a brine source uses an Archimedean screw to elevate water to an elevated point. The water is then filtered to desalinate the water through a series of filters arranged in a vertical shaft using gravity to move the water through the filters. The vertical nature of the screw and shaft reduce land requirements and costs. A power source turns the screw and relies on renewable energy sources, such as solar, wind, and tidal/wave power. A turbine is used to recapture any energy in the descending water. The screw, renewable energy power source, and turbine reduce the energy requirements and costs. A brine recycling system recovers the removed brine and various elements and minerals are separated.
