Abstract: A multi-function fluid treatment system which can filter liquids or diffuse gases into liquids. To achieve filtration, the system includes a housing with multiple, closely-spaced filter cartridges therein. The cartridges are connected to a drive system which rotates them in unison. Fluids to be filtered enter the housing and surround the rotating cartridges. Cartridge rotation scrubs solids from the cartridges and promotes fluid flow into the cartridges. Filtered fluids collected within the cartridges thereafter exit the system. To achieve gas diffusion, the housing is filled with a selected liquid. During cartridge rotation as discussed above, a gas is introduced into the interior of each cartridge which is constructed of a porous material. The gas diffuses outwardly during cartridge rotation, causing substantial mixing of the gas and fluid, with gas diffusion into the fluid. Cartridge rotation also prevents solids from accumulating thereon to achieve maximum gas delivery.

Abstract: 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.
