Abstract: The present invention relates to water filters utilizing disc filter elements and in particular, to such a filtering apparatus having self-cleaning capabilities by utilizing automated back-flushing to clean the filtering elements where the self-cleaning process is enhanced by introducing a secondary flowing fluid, preferably atmospheric air, into the back-flushing stream. The filter apparatus is further enhanced with a disc filter spine having a plurality of spray nozzles arranged on the spine channels that may be adapted to produce a cleaning flowing fluid jet stream at a variety of angles facilitating cleaning, separation and spinning of the disc filtering elements. The filter apparatus may further enhance the cleaning process by introducing a flushing apparatus adapted to facilitate removal of effluent from the filter.

Abstract: The present invention relates to fluid filtering apparatuses, for applications such as water filtration, that utilizes screen filters, and in particular, to such a filtering apparatus having autonomously controlled self-cleaning capabilities. A self-cleaning filter apparatus including a filtering housing for filtering a fluid across a screen filter, a flushing chamber for housing filtered debris, and a control assembly for autonomously switching between filtering phases of the filter based on the differential pressure across the filter that is channeled along portions of the control assembly, the control assembly including a flush valve assembly, a three position two way (3/2) valve and a differential pressure (DP) switch.

Abstract: A filtering apparatus (100) having a filtering mode and a self-cleaning mode, the apparatus provided for filtering an upstream flowing fluid with filtering elements (20) in the form of a plurality of stackable discs during filtering mode utilizing a first flow direction, apparatus (100) also configured to self-clean the filtering elements (20) the apparatus (100) including an internal fluid diverter (110,210, 310) that is internal to the filter housing. The position of the internal fluid diverter determines the direction of fluid flow through the filter housing and the filter phase. The position of the internal fluid diverter is controlled with a controller disposed external to the filter housing that may be manipulated either manually or by automated means.
