Abstract
The present invention is directed to a method for filtering fluid, preferably effluent fluid in a septic system, by providing a staged, filtering array in an effluent flow path, the stages positioned in an orientation designed to maximize filtering capability in conjunction with predetermined aperture positions and dimensions.
Claims34
A method for filtering effluent comprising:
- providing a filtering assembly, said assembly including a plurality of inclined substantially planar components spaced apart by two or more partitions, said two or more partitions creating a series of apertures of varying dimension which progressively decrease in the direction of the effluent flow;
- said two or more partitions spaced apart from each other along the direction of effluent flow;
- providing a housing dimensioned to receive said filtering assembly, said housing including an inlet and an outlet;
- providing the effluent flow to said assembly in said housing;
- and
- directing effluent flow through said assembly such that only the effluent having predetermined characteristics moves past said two or more partitions and adjacent said inclined planar components.

A method for filtering effluent comprising:
- providing a filtering assembly, said assembly including a first and second substantially planar component, said first and second planar components spaced apart by at least first and second partitions, said first and second partition spaced apart along the direction of an effluent flow having varying dimensions relative to each other, said partitions each including at least one aperture, said aperture bounded partially by a surface of the said first or second planar components, with at least one planar component positioned at an incline;
- providing a housing dimensioned to receive said filtering assembly, said housing including an inlet and an outlet and a means for positioning said assembly within said housing;
- providing an effluent flow to said assembly in said housing;
- directing effluent flow through said assembly such that only the effluent having predetermined characteristics moves past said partitions and angled planar surfaces.

An apparatus for filtering effluent comprising:
- a filtering assembly, said assembly including a plurality of inclined substantially planar components spaced apart by two or more partitions;
- said two or more partitions spaced apart from each other along the direction of effluent flow;
- and
- said two or more partitions oriented to create a series of apertures of varying dimension such that said aperture dimensions progressively decrease in the direction of the effluent flow.

An apparatus for filtering effluent comprising:
- a filtering assembly, said assembly including a first and second substantially planar component, said first and second planar components spaced apart by at least a first and second partition, said first and second partition are spaced apart along the direction of an effluent flow, said partitions each including at least one aperture, said aperture bounded partially by a surface of said first or second planar components, with at least one planar component positioned at an incline;
- a housing dimensioned to receive said filtering assembly, said housing including an inlet and an outlet and a means for positioning said assembly within said housing;
- and
- wherein said first partition, when in position with said first or second planar component provides apertures having a first dimension, and said second partition when in the first or second position with a planar component provides apertures having a second dimension, such that said first and second aperture dimensions are not equal.
