Abstract
A reverse osmosis system and method of operating the same includes a membrane housing comprising a reverse osmosis membrane therein. The membrane housing has a feed fluid input, a brine outlet and a permeate outlet; The system further includes a charge pump, a plurality of valves and a tank having a volume comprising a movable partition dividing the volume into a first volume and a second volume. The plurality of valves selectively couples the charge pump to the first volume or the second volume and the brine outlet to the second volume or the first volume respectively.
Claims15
A reverse osmosis system in communication with a fluid reservoir comprising:
- a membrane housing comprising a reverse osmosis membrane therein, said membrane housing comprising a feed fluid input, a brine outlet and a permeate outlet;
- a charge pump;
- a plurality of valves;
- and
- a first volume disposed in a first bag and a second volume disposed in a second bag, wherein said first bag and said second bag are disposed in a body of water;
- said plurality of valves operating so that in a first mode, the charge pump couples a feed reservoir to the first volume while the brine outlet and the feed fluid input are simultaneously connected to the second volume, and in a second mode, the charge pump is coupling the feed reservoir to the second volume while the brine outlet and the feed fluid input are simultaneously connected to the first volume,
- wherein the first mode and second mode are configured for alternating operation.
A method comprising:
- filling a first volume disposed in a first bag and a second volume disposed in a second bag, wherein said first bag and said second bag are disposed in a body of water;
- producing permeate with fluid from the second volume by passing the fluid through a membrane of a membrane housing, said membrane housing comprising a feed fluid input, a brine outlet and a permeate outlet;
- controlling a plurality of valves so that in a first mode, a charge pump is coupling a feed reservoir to the first volume while the brine outlet and the feed fluid input are simultaneously connected to the second volume, and in a second mode, the charge pump is coupling the feed reservoir to the second volume while the brine outlet and the feed fluid input are simultaneously connected to the first volume,
- wherein the first mode and second mode are configured for alternating operation.
