Multi-function self-cleaning fluid treatment system and method for using the same

A high efficiency, self-cleaning fluid filtration system comprising:

• a housing;
• three individual elongate filter cartridge units positioned within said housing in a triangular arrangement in which each of said cartridge units is spaced equidistantly from each other in order to form an open center zone surrounded by said cartridge units, each of said cartridge units comprising a longitudinal axis, an upper end, a lower end, a 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;
• an elongate vertical support member secured to and within said housing, said support member being positioned within said open center zone surrounded by said filter cartridge units, said support member further comprising three elongate channel members secured thereto and spaced equidistantly from each other on said support member, each of said channel members comprising a first end, a second end, a first side panel, and a second side panel spaced apart from said first side panel to form a gap therebetween, said first side panel further comprising an outer longitudinal edge having a ridge portion thereon which extends inwardly into said gap, said second side panel further comprising an outer longitudinal edge having a ridge portion thereon which extends inwardly into said gap, said vertical support member further comprising three elongate brush assemblies thereon, each of said brush assemblies comprising a longitudinal retaining strip comprising a row of bristles secured to said strip and extending outwardly therefrom, each of said brush assemblies being positioned within said gap in one of said channel members and retained therein by engagement of said retaining strip against said ridge portion on said first side panel and said ridge portion on said second side panel, said first side panel and said second side panel of each of said channel members being tilted inwardly toward each other at said second end thereof to prevent premature brush assembly displacement through said second end, said support member being oriented within said open center zone surrounded by said cartridge units so that said side wall portion of each of said cartridge units is placed against and in direct contact with said bristles on at least one of said brush assemblies, said brush assemblies removing collected debris from said side wall portion of each of said cartridge units during rotation thereof;
• and
• drive means operatively connected to all of said cartridge units for simultaneously rotating each of said cartridge units around said longitudinal axis thereof, 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, said brush assemblies removing said debris from said side wall portion of each of said cartridge units during said rotation thereof to further increase said efficiency of said filtration system.
