NOVELTY - A fluid filtration device (400) comprises an influent feed tube (406); an influent receiving bowl in fluid communication with the influent feed tube; and radial arms having filters configured to rotate an axis within the influent receiving bowl. The device further comprises anaerobic digester, and influent vane(s) (408) within the influent feed tube(s) and radial arms to control the speed and direction of travel of the influent.    USE - The fluid filtration device is used for filtering fluids, e.g. liquids or gases; for drinking water and wastewater treatment for municipalities; for non-community wastewater systems and housing developments; for wastewater treatment for commercial business developments, condominiums, malls, hotels/motels, office buildings, hospitals, resorts, and government and military installations; for isolation, separation, purification, removal, recovery, and/or concentration of biological components in the pharmaceutical and biotechnology industries; for water clean-up in power plants; and for water and wastewater clean-up in industries including dairy, food processing, farming, agriculture, chemical, or petroleum.    ADVANTAGE - The fluid filtration device eliminates five separate operations typically performed in wastewater treatment, thus operating in less time and less space, at lower cost, while consuming less than 1/3 of electricity. Further, the vanes of the fluid filtration device enhance a Coriolis effect on the influent which has an antifouling effect as the influent crosses the filters within the radial arms. The anaerobic digester produces methane gas from undigested biosolid received from the filtration device, in which methane can be a source of heat and electrical energy generation to run the operation of the centrifugal fluid filtration system, and/or provide electricity to municipal systems.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a waste water treatment system; and    (2) a radial filtration arm for use in the fluid filtration device.    The fluid filtration device is in fluid communication with a water supply external to the fluid filtration device. The water supply is an ocean, bay, river, stream, lake or subterranean water table.
