Abstract
Filtration system including flow-reversing subsystems are provided, as are methods for separating feed streams into reject streams and permeate streams. In one embodiment, the filtration system includes a reversible flow loop having an inlet configured to receive a pressurized feed stream. At least one filter unit is positioned in the reversible flow loop and configured to separate the pressurized feed stream into a permeate stream and a reject stream. A flow-reversing subsystem is further positioned in the reversible flow loop and is operable in: (i) a forward flow mode wherein the flow-reversing subsystem pressurizes the feed stream to flow through the reversible flow loop in a forward flow direction, and (ii) a reverse flow mode wherein the flow-reversing subsystem pressurizes the feed stream to flow through the reversible flow loop in a reverse flow direction opposite the forward flow direction.
