Abstract:
Concentration control in filtration systems and associated methods are generally described. Streams originating from upstream filters and having similar concentrations of a target minor component and/or similar osmotic pressures can be mixed and subsequently filtered within additional filters. Certain embodiments comprise recycling an output stream produced by a filter to a filter feed stream, wherein the output stream and the filter feed stream have similar concentrations of a target minor component and/or similar osmotic pressures. Such strategic mixing and/or recycling can reduce the amount of energy and/or the amount of filtration medium surface area required to achieve a desired concentration of the target minor component in a final product stream.

Claim (Index 4):
A system according to  claim 1 , further comprising:\n a set of reverse osmosis membrane filtration units in a second grouping to provide second stage filtration, the set having at least one member, and wherein the system is configured to recycle retentate from the retentate stream outlet, of a selected pass of the second grouping, to the feed stream inlet of a pass of the first grouping, wherein the first fluid corresponds to fluid in the feed stream inlet of the pass of the first grouping and the second fluid corresponds to the retentate from the retentate stream outlet of the selected pass of the second grouping.
