  • Patent number: 10583395
    Abstract: The present disclosure is directed to a forward osmosis system/process utilized primarily in conjunction with a subsurface irrigation system/process. Saline wastewater or naturally saline water is treated using forward osmosis membranes that draw at least partially purified water from the wastewater into an osmotic draw solution (draw solution). The resulting diluted osmotic draw solution is then circulated through the subsurface irrigation system including one or more tubular membranes that reject the draw solution while permitting water in the diluted draw solution to pass through.
    Type: Grant

  • Patent number: 10390500
    Abstract: Presented herein are membranes for use in separating solids including salts from water. One application of such membranes is in a sub-surface irrigation system that that utilizes a saline or tainted water as a feed source. In various embodiments, the membranes operate on a solution diffusion principle. In other embodiments the membranes operate on an ultrafiltration principle and/or a solution diffusion principle. In any embodiment, the membranes operate similar to pervaporation membranes suitable for non-pressure driven systems. The membranes are designed to provide increased flux rate while separating solids such as salts from water.
