ABSTRACT:
A self-cleaning water filtration system includes a pre-filter to filter oils and relatively medium sized particles in a water flow, a multi-stage filter to purify and provide a second level of filtration to the water flow, and a self-cleaning filter to provide a third level of filtration to the water flow. Water flow through the filter media of the self-cleaning filter is redirected to flush waste to a containment-tank filter. The self-cleaning filter has a purge output, which may spray the pre-filter to substantially remove particles from the pre-filter for collection in the containment tank. The multi-stage filter may have at least two layers of filter media. The pre-filter may be disposable and comprised of a mineral sanitizer positioned between two layers of an oil absorbing fabric.
