NOVELTY - The centrifugal or reaction filter apparatus comprises a canister housing (200), a central annular filter element, centrifugal radial fins, a drive mechanism, an inlet (120) adjacent to a top of the canister, a solids outlet adjacent to a bottom of the canister, and external centrifugal radial fins. The canister housing has a frusto-conical internal surface, an outlet adjacent to a minor diameter of a frusto-conical internal wall of the canister, and an inlet spaced axially towards a major diameter of an internal surface receiving liquid and solids.    USE - The centrifugal or reaction filter apparatus is useful for removing dissolved and suspended solids from municipal, industrial and agricultural waste water to generate potable water and recycled oil and biosolids that are useful as feed stock for hydrocarbon fuel generation.    ADVANTAGE - The centrifugal or reaction filter apparatus rapidly and economically removes the solids from the waste water thus providing the large amount of potable water with high purity, and is easy to operate at a high or cold temperature.    DETAILED DESCRIPTION - The centrifugal or reaction filter apparatus comprises a canister housing (200), a central annular filter element, centrifugal radial fins, a drive mechanism, an inlet (120) adjacent to a top of the canister, a solids outlet adjacent to a bottom of the canister, and external centrifugal radial fins. The canister housing has a frusto-conical internal surface, an outlet adjacent to a minor diameter of a frusto-conical internal wall of the canister, and an inlet spaced axially towards a major diameter of an internal surface receiving liquid and solids. The central annular filter element has circumferentially spaced filter pores and a frusto-conical outer surface. The centrifugal radial fins extend radially from an external surface of the annular filter element to the frusto-conical internal surface of the canister housing, and are rotatably supported on a central shaft (150) including circumferentially spaced radial mixing blades on the central shaft. The frusto-conical outer surface conforms to the frusto-conical internal surface of the canister driving the solids received from the inlet of the canister towards the minor diameter of the canister. The drive mechanism rotates the external centrifugal radial fins. The minor diameter of the frusto-conical internal surface of the canister is adjacent to the bottom of the canister. The external centrifugal radial fins drive the solids received from the inlet towards the bottom of the canister compressing the solids. Each blade includes a radial central portion, a first side portion, and a second side portion. The radial central portion extends perpendicular to an axis of the central shaft. The first side portion of the blade adjacent to the central shaft radially and circumferentially extends at an obtuse angle relative to the radial central portions. The second side portion of the blade extends from an opposite side of the radial central portion spaced radially from the first side portions that are radially and circumferentially extending at the obtuse angle to the radial central portion circulating a fluid downwardly adjacent to a distal end of the radial fins.
