A high efficiency, self-cleaning system for separating solid materials from liquids. The system includes a primary housing having at least one inlet and a plurality of cylindrical filter cartridges therein which are directly adjacent to and in close proximity with each other. The lower end of each cartridge is positioned on a spring-biased bearing member, with the upper end having an opening therein. Positioned within the opening and connected to each cartridge is a tubular shaft attached to a pulley-type motor drive system. The drive system is used to rotate the cartridges in a selected direction. In operation, fluids to be filtered enter the housing and come in direct contact with the rotating cartridges. Rotation of the multiple cartridges and close proximity of the cartridges to each other creates fluid turbulence within the housing. This turbulence scrubs collected solids from the cartridges and promotes fluid flow into the cartridges. Fluids collected within the cartridges pass into the tubular shafts and out of the system. As a result, the fluids are effectively filtered in a rapid and efficient manner while minimizing system down-time.

A high efficiency liquid filtration system comprising: a primary housing comprising at least one inlet port therein; a plurality of elongate filter cartridge units positioned within said housing, each of said cartridge units comprising a longitudinal axis, an upper end, a closed lower end, a tubular side wall portion comprised of filter material, and an interior region therein surrounded by said side wall portion for receiving fluid materials which pass through said side wall portion, each of said cartridge units being rotatable around said longitudinal axis thereof and further comprising at least one outlet at said upper end for allowing said fluid materials within said interior region to pass outwardly therefrom; a plurality of tubular shaft members, each of said shaft members being connected to one of said cartridge units and comprising an open first end, a closed second end, and a medial portion between said first end and said second end, said medial portion comprising a tubular outer wall and an internal passageway therein surrounded by said outer wall, said outer wall further comprising at least one port therethrough between said first end and said second end of each of said shaft members, said port providing access to said internal passageway, said first end of each of said shaft members terminating at, and being connected to said upper end of one of said cartridge units; and drive means operatively connected to said second end of each of said shaft members and positioned outside of said primary housing for simultaneously rotating each of said cartridge units around said longitudinal axis thereof, said second end of each of said shaft members being positioned outside of and above said primary housing so that said second end of each of said shaft members may be operatively connected to said drive means, said rotating of said cartridge units by said drive means causing said cartridge units to filter solid materials from said fluid materials with increased efficiency.
