ABSTRACT:
A device for filtering fluid includes a hollow housing having a fluid inlet and a fluid outlet. A filter element formed of fluid permeable material is disposed within the housing for filtering fluid entering the fluid inlets, the fluid passing through the element and out the fluid outlet. The element has a generally cylindrical configuration with the permeable material forming a plurality of elongated, radially extending pleats. The pleats are supported by spacers having a plurality of blades attached to a web with channels therebetween. The element is used as a septum for supporting a diatomaceous earth precoat. A regeneration piston creates fluid flows within the filter that cause the element to flutter, thereby displacing DE precoat from the septum for regeneration.
