ABSTRACT:
A multi-function fluid treatment system which can filter fluids or diffuse gases into liquids. To achieve filtration, the system includes a housing with multiple 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 cartridges. Cartridge rotation scrubs solids from the cartridges and promotes fluid flow therein. A separate cleaning system is also provided which involves a cartridge wiping assembly having multiple wiping members thereon. The wiping members directly contact the cartridges to remove collected debris and preferably involve multiple bristles secured to a vertical support member. The support member may consist of dual wires secured together with the bristles therebetween. The bristles can also be arranged in elongate rows (one row per cartridge) on the support member. In either embodiment, the wiping assembly improves filtration efficiency and reduces maintenance requirements.
