The device comprises a pump-filter hybrid system that uses rotational motion to produce pressure to drive liquid through filter elements, capturing filtrate in an isolated chamber of the device and rejecting separated solids into a second isolated chamber. The fluid filtration device, which can be configured to filter a wide variety of fluids, comprises: an influent input manifold; an impeller bowl and filter assembly configured to rotate about an axis; a barrier and muting configuration to catch and distribute filtrate; a barrier and routing configuration to catch and distribute rejected solids. ## Claims ### Claim 1 A fluid processing system comprising: a. a first bowl, with a bottom surface and a side wall having an inner surface and an outer surface defining an enclosure wherein the side wall extends from the bottom surface at an angle from 10-20° from the vertical, having at least one filter element positioned in the side wall of the first bowl in fluid communication between an interior of the first bowl and an exterior of the first bowl; b. an input manifold adapted and configured to receive an influent fluid and to deliver the influent to an area adjacent the bottom surface of the first bowl; c. a partition adapted and configured to isolate an influent filtrate from an influent solid; and d. a drive system adapted and configured to control a rotational movement of the first bowl. ### Claim 2 (depends on 1) The fluid processing system of claim 1 further comprising at least one pump vane positioned in a bottom surface of the first bowl wherein the pump vane is adapted and configured to propel the influent outward from a central axis when the first bowl is rotating. ### Claim 3 (depends on 1) The fluid processing system of claim 1 further comprising a back-flush system having a spray nozzle and pump assembly to spray fluid through the filter from an exterior of the first bowl to the interior of the first bowl. ### Claim 4 (depends on 1) The fluid processing system of claim 1 further comprising one or more secondary bowls nested around the first bowl and a common axis of rotation adapted and configured to cause the influent to be processed in stages. ### Claim 5 (depends on 4) The fluid processing system of claim 4 wherein the one or more nested secondary bowls have an angle from a bottom surface to an upper edge of the side surface that is the same or different from the angle of the first bowl. ### Claim 6 (depends on 1) The fluid processing system of claim 1 further comprising an enclosure adapted and configured to isolate the system from an environment wherein the enclosure further comprises one or more input/output interfaces. ### Claim 7 (depends on 1) The fluid processing system of claim 1 wherein the at least one filter element is has a filtering capacity of from several hundred micrometers to sub-micrometer. ### Claim 8 (depends on 7) The fluid processing system of claim 7 wherein the at least one filter elements is adapted and configured to filter in a single stage or multiple stages. ### Claim 9 (depends on 1) The fluid processing system of claim 1 wherein the one or more filters are formed from one or more of plastic screen, metal screen, microfiber material, woven fibers, sintered metal, and compressed paper. ### Claim 10 A method of filtering fluid comprising: a. introducing an influent into a fluid processing system comprising a first bowl, with a bottom surface and a side wall having an inner surface and an outer surface wherein the side wall extends from the bottom surface at an angle from 10-20° from the vertical, having at least one filter element positioned in the side wall of the first bowl in fluid communication between an interior of the first bowl and an exterior of the first bowl, an input manifold adapted and configured to receive an influent fluid and to deliver the influent to an area adjacent the bottom surface of the first bowl, a partition adapted and configured to isolate an influent filtrate from an influent solid, and a drive system adapted and configured to control a rotational movement of the first bowl b. rotating the first bowl; and c. creating a pressure to force a fluid component of the influent through filter elements while pushing a solid component of the influent over a top rim of the bowl. ### Claim 11 (depends on 10) The method of claim 10 further comprising the step of propelling the influent outward by a pump vane located on the bottom surface of the bowl. ### Claim 12 (depends on 10) The method of claim 10 further comprising the step of spraying a fluid other than the fluid component of the influent through the filter. ### Claim 13 (depends on 10) The method of claim 10 further comprising the step of filtering a fluid component of the influent through one or more nested bowls. ### Claim 14 (depends on 10) The method of claim 10 further comprising the step of isolating the system from the environment. ### Claim 15 A fluid processing device comprising: a. a first bowl having at least one filter element positioned in the side wall of the first bowl in fluid communication between an interior of the first bowl and an exterior of the first bowl; b. an input manifold adapted and configured to receive an influent fluid and to deliver the influent to an area adjacent the bottom surface of the first bowl; c. at least one pump vane positioned in a bottom surface of the first bowl wherein the pump vane is adapted and configured to propel the influent outward from a central axis when the first bowl is rotating; and d. a drive system adapted and configured to control a rotational movement of the first bowl. ### Claim 16 (depends on 15) The fluid processing device of claim 15 wherein a bottom surface of the bowl and a side wall of the bowl have an inner surface and an outer surface and further wherein the side wall extends from the bottom surface at an angle from 10-20° from the vertical. ### Claim 17 (depends on 15) The fluid processing device of claim 15 further comprising a back-flush system having a spray nozzle and pump assembly to spray fluid through the filter from an exterior of the first bowl to the interior of the first bowl. ### Claim 18 (depends on 15) The fluid processing device of claim 15 further comprising one or more secondary bowls nested around the first bowl and a common axis of rotation adapted and configured to cause the influent to be processed in stages. ### Claim 19 (depends on 18) The fluid processing device of claim 18 wherein the one or more nested secondary bowls have an angle from a bottom surface to an upper edge of the side surface that is the same or different from the angle of the first bowl. ### Claim 20 (depends on 15) The fluid processing device of claim 15 further comprising an enclosure adapted and configured to isolate the system from an environment wherein the enclosure further comprises one or more input/output interfaces. ### Claim 21 (depends on 15) The fluid processing device of claim 15 wherein the at least one filter element is has a filtering capacity of from several hundred micrometers to sub-micrometer. ### Claim 22 (depends on 21) The fluid processing device of claim 21 wherein the at least one filter elements is adapted and configured to filter in a single stage or multiple stages. ### Claim 23 (depends on 15) The fluid processing device of claim 15 wherein the one or more filters are formed from one or more of plastic screen, metal screen, microfiber material, woven fibers, sintered metal, and compressed paper. ### Claim 24 (depends on 15) The fluid processing device of claim 15 further comprising a refrigeration system adapted and configured to change a temperature of at least one of the influent or the one or more filters.
