Abstract: Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.

Abstract: A fluid filtration device is provided that can be used for separating solids from fluids. In some embodiments, the fluid filtration device comprises a hollow housing and a hollow filter assembly located within the housing. Fluid to be filtered is provided to the inside of a filter material in the filter assembly and passes outward toward the housing. In some embodiments one or more flow-directing features are located between the filter assembly and the housing, and may aid in the flow of fluid to a filtered outlet after passing through the filter. The flow-directing features may comprise, for example, channels that extend the length of the filter.
