Abstract: A method and apparatus for separating a carrier fluid from particles held in suspension in the fluid and which are of greater density than the fluid, which involves flowing the fluid with the particles therein along a screen while rapidly rotating the screen and fluid, the screen extending primarily radially from the axis of rotation. A high flow rate of fluid through the screen is achieved with minimum fouling of the screen by large particles lodging in the screen, and even particles of a size smaller than the holes in the screen do not pass through the screen.

Abstract: A separation process of the reverse osmosis type useful for generating fresh water by forcing salt water against a semipermeable membrance that allows only pure water to pass, which uses centrifugal forces created by rotating basket to build up a pressure head of water supplied to the basket to force water through the membrance. The pure water can be expelled by a nozzle in a direction to help rotate the basket. The membrance can be in the form of a spiral or layers extending perpendicular to the axis, to increase the membrane area within a basket of given size. The membranes can extend radially with respect to the axis of rotation, and supply and removal conduits can be positioned to continually flow water in an outward radial direction to prevent the build-up of polarization layers on the membrane surfaces.
