US 2026/0285705 A1 · WATER INTAKE FILTRATION SYSTEM

Abstract

A filtration system produces filtered water and returns captured solids to source water. The filtration system includes an intake filter subsystem fluidically coupled to the source water and to at least one pump, the intake filter subsystem configured to receive a flow of source water, capture organisms from the flow of source water, and produce a filtered intake flow of water. The filtration system is configured to operate in a plurality of operating modes, wherein, in a first operating mode, the filtered intake flow is received from the intake filter subsystem along a first fluid pathway to produce filtered water at a first system outlet, and, in a second operating mode, a flow of filtered water is provided to a second fluid pathway and a second system outlet to wash captured organisms back into the source water and maintain the source water environment.

Dependent claims

A filtration system for producing filtered water and returning solids to a source water environment, comprising:

at least one pump;
an intake filter subsystem fluidically coupled to the source water and the at least one pump, wherein the intake filter subsystem comprises a plurality of filters separated by interstitial space(s) defining a fluid flow path between a downstream face of an upstream filter and an upstream face of a downstream filter, and the intake filter subsystem is configured to receive a flow of source water, capture organisms from the flow of source water, and produce a filtered intake flow of water;
and
wherein the system is configured to operate in a plurality of operating modes, wherein, in a first operating mode, the filtered intake flow is received from the intake filter subsystem along a first fluid pathway to produce filtered water at a first system outlet, and, in a second operating mode, a flow of filtered water is periodically provided to a second fluid pathway and a second system outlet to wash captured organisms alive back into the source water, and wherein the second fluid pathway comprises the interstitial space and flow across the downstream and upstream filter faces to the second system outlet.

A multi-stage filtration system for producing filtered water and returning captured solids to source water, comprising:

at least one pump;
an intake filter subsystem, fluidically coupled to the at least one pump, configured to receive a flow of source water and filter out organisms from the flow of source water;
a self-cleaning subsystem coupled to the intake filter subsystem and configured to periodically remove and displace organisms from the intake filter subsystem into an interstitial space between successive filters of the intake filter subsystem;
and
wherein the multi-stage filtration system is configured to operate in a plurality of operating modes wherein, in a first operating mode, the intake filter subsystem receives the flow of source water to produce a flow of filtered water along a first fluid pathway, and, in a second operating mode, the flow of filtered water is provided to the interstitial space and flows along a second fluid pathway across downstream and upstream filter faces of the successive filters and through an outlet of the multi-stage filtration system to return the organisms to source water.
