Abstract: The reverse osmosis centrifuge converts rotational energy into fluid velocity and conserves the energy placed into the concentrate. As concentrate travels back towards the center of the reverse osmosis centrifuge, the velocity of the fluid is converted into rotational force, thus conserving energy placed into the concentrate. To accomplish this, the reverse osmosis centrifuge includes a support shaft, a plurality of receiving tubes, a plurality of housings with filters therein, a plurality of departure tubes, and a permeate trough. The plurality of receiving tubes are coupled to a top of the plurality of housings, while the plurality of departure tubes are coupled to a bottom of the plurality of housings. Centrifugal force creates the permeate and concentrate. The permeate exits the plurality of housings and is deposited into the permeate trough. The concentrate travels through, and exists from, the plurality of departure tubes.
