ABSTRACT:
Permeator systems containing selectively permeable membranes suitable for pressure-influenced fluid separations and processes for operating permeator systems for the separation of fluids are disclosed which can provide high turn down ratios of permeate while maintaining substantially constant concentrations of at least one permeating moiety in the permeate. In accordance with the invention, the permeator system comprises a plurality of permeator stages, each of which permeator stages receive a feed stream, and the flow of permeate from at least one permeator stage is initiated and terminated at predetermined rates of permeate fluid flow from the permeator system.
