Self-cleaning water filtration system and method

A self-cleaning filtration system comprising:

• a pre-filter to provide a first level of filtration to filter oils and particles in a water flow;
• a multi-stage filter to at least partially purify and provide a second level of filtration to the water flow, the multi-stage filter comprising a plurality of layers of media;
• a self-cleaning filter to provide a third level of filtration to the water flow, wherein the water flow through filter media of the self-cleaning filter is redirected to flush waste from the self cleaning filter;
• a containment tank to receive the waste from a purge output of the self-cleaning filter when the water flow through the filter media of the self-cleaning filter is redirected,
• wherein the water flow through the filter media of the self-cleaning filter is redirected in response to an occurrence of either a change in output water pressure of the self-cleaning filter or an indication from a timer that occurs on a regular basis, and
• wherein the purge output has a nozzle to spray a first-level media of the pre-filter to substantially remove the particles from the pre-filter for collection in the containment tank when the water flow through the filter media of the self-cleaning filter is redirected.

A self-cleaning filtration system comprising:

• a pre-filter to provide a first level of filtration to filter oils and particles in a water flow;
• a multi-stage filter to at least partially purify and provide a second level of filtration to the water flow, the multi-stage filter comprising a plurality of layers of media;
• a first self-cleaning filter to provide a third level of filtration to the water flow, wherein the water flow through filter media of the first self-cleaning filter is redirected to flush waste from the self cleaning filter;
• a first pump positioned between the multi-stage filter and the self-cleaning filter to generate a first water flow by drawing water through the pre-filter and the multi-stage filter and to pump water through the first self-cleaning filter;
• a second self-cleaning filter;
• a second pump to generate a second water flow by drawing water through a suction inlet and to pump water through the second self-cleaning filter;
• and
• a containment tank to receive waste from purge outputs of the first and second self-cleaning filters for removal when the respective water flow through either the first or second self-cleaning filter is redirected,
• wherein the purge outputs direct water through a nozzle to spray a first-level media of the pre-filter to remove the particles that reside on the pre-filter for collection in the containment tank when the respective water flow through either the first or second self-cleaning filter is redirected.

A filtration system comprising:

• a pre-filter to provide a first level of filtration to filter oils and relatively medium sized particles in a water flow;
• a multi-stage filter;
• to at least partially purify and provide a second level of filtration to the water flow, the multi-stage filter comprised of a plurality of layers of media;
• and
• a self-cleaning filter to provide a third level of filtration to further filter the water flow, wherein the water flow through filter media of the self-cleaning filter is redirected to flush waste from the self cleaning filter, and
• wherein a purge output of the self-cleaning filter is configured to spray the pre-filter with redirected water to remove at least some of the particles from the pre-filter, and
• wherein the redirected water from the purge output is recirculated after filtering through the multistage filter.
