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 8):
A reverse osmosis separation system for enriching a minor component of a liquid feed, the liquid feed having concentrations of a major component and the minor component, the minor component being non-ionic and having a molecular weight less than about 150 g/mole, wherein the concentration of the minor component in the liquid feed is at least about 0.1% to less than 50% by weight, the system comprising:\n a first filter comprising a first filtration medium defining a permeate side and a retentate side of the first filter; a second filter comprising a second filtration medium defining a permeate side and a retentate side of the second filter; a third filter comprising a third filtration medium defining a permeate side and a retentate side of the third filter; a fluidic connection between: (a) the liquid feed and the retentate side of the first filter; (b) the permeate side of the first filter and the retentate side of the second filter; (c) the retentate side of the first filter and the retentate side of the third filter; and (d) the retentate side of the second filter and the retentate side of the third filter or the retentate side of the second filter and the permeate side of the third filter, wherein each of the fluidic connections is configured to convey a liquid stream; and a feedback control mechanism configured to control: a lesser of the concentration of the minor component (1) in the liquid stream within the fluidic connection between the retentate side of the third filter and the retentate side of the first filter and (2) in the liquid feed to match within 50% a greater of the concentration of the minor component (1) in the liquid stream within the fluidic connection between the retentate side of the third filter and the retentate side of the first filter and (2) in the liquid feed; and/or the concentration of the minor component in the liquid stream within the fluidic connection between the retentate side of the second filter and the permeate side of the third filter, such that a lesser of the concentration of the minor component (1) in the liquid stream leaving the permeate side of the third filter and (2) in the liquid stream leaving the retentate side of the second filter matches within 50% a greater of the concentration of the minor component (1) in the liquid stream leaving the permeate side of the third filter and (2) in the liquid stream leaving the retentate side of the second filter.
