Definitions

  • FIG. 6A is a top view of another embodiment of a fluid separation apparatus
  • further embodiments of separation devices disclosed herein include a spacer for positioning the separator 114 at the EZ/bulk fluid boundary or at the EZ/hydrophilic material boundary.
  • the spacer can be made of any acceptable material and can be of any shape sufficient to either maintain the separator 114 at a fixed position relative to a portion of the housing or at a fixed position relative to the EZ-generating hydrophilic surface.
  • the spacer can be configured to adhere to the housing or can be formed from the housing itself, for example, by etching.
  • one or more spacers 220 can be used to position the EZ-generating material of the central plate 214 at a predefined distance from the second plate structure 208.
  • the spacers 220 can be adhered to the central plate 214 and/or the second plate structure 208, or they can be formed on the central plate 214 or the second plate structure 208. While the spacers 220 in the embodiment illustrated in FIGS. 2A and 2B are in a tear-shaped configuration, any shape can be used as long as the shape is sufficient to ensure the positioning of the separator 214 at or near the boundary of the exclusion zone and bulk fluid layers.
  • the apparatus of FIG. 3 A can further be scaled up into the apparatus embodied in FIG. 3B to generate even larger amounts of exclusion zone fluid.
  • a module 304 containing multiple stacks of circular separation apparatuses is submerged in a tube containing water.
  • the centrally-located channel 212 in each circular apparatus is connected to the second outlet 212 that permits bulk fluid to exit the apparatus.
  • Each of the centrally-located channels 212 is configured to connect to a manifold which is used to draw the bulk fluid out of the module 304.
  • the bulk fluid is drawn into a different channel and exits the apparatus via the bulk outlet 310.
  • One or more pumps or similar suction devices can be used to control the amount of EZ and/or bulk fluid exiting the apparatus.
  • the force exerted by the pump or pumps can be varied in order to maximize the amount of EZ fluid that is drawn through the separators and into the first outlet.
  • the force exerted by the pump drawing bulk fluid through the second fluid outlet can be optimized to ensure that no bulk fluid is drawn into the first fluid outlet.
  • the force exerted by the pump drawing bulk fluid through the first fluid outlet can be optimized to ensure that no EZ fluid is drawn into the second fluid outlet.
  • FIG. 4B illustrates an end view of the apparatus of FIG. 4A.
  • the inner surface of the fluid outlet 406 end of the first tubular structure 402 and the plurality of recesses 410 formed around the fluid inlet end of the second tubular structure 408 define a fluid exit region that is configured to receive an outer region of fluid flowing from the fluid outlet 406 in the first tubular structure 402 into the fluid inlet in the second tubular structure 408 to thereby separate the outer region of the fluid (e.g., an exclusion zone) from an inner region of the fluid.
  • the solute-containing inner region of fluid then continues into the fluid-flow lumen of the second tubular structure.

  • An inner tube or "waste outlet" connected to the fluid outlet end 406 of the first tubular structure 402 can be used to collect the solute-containing fluid, which is either discarded or saved for recycling.

  • a suitable adhesive 518 such as, without limitation, double-sided adhesive tape.
  • the width of the hydrophilic surface 516 portion of the ring is sufficient to permit the formation of an exclusion zone in fluid passing over the hydrophilic surface 516.
  • the second plate 510 structure, hydrophilic surface 516, adhesive layer 518, and first plate 508 structure have one or more holes which are configured to receive one or more fasteners 524 (such as, without limitation, screws) for holding the components of the apparatus together.

Abstract

L'invention concerne des appareils de séparation de fluides contenant des solutés et leurs procédés d'utilisation. Les appareils peuvent comprendre une surface hydrophile située sur le trajet d'écoulement du fluide et conçue de façon que, quand un fluide polaire emprunte ledit trajet d'écoulement de fluide, une zone d'exclusion adjacente à la surface hydrophile se forme. Un séparateur est agencé sur ledit trajet d'écoulement de fluide et permet de séparer le fluide à l'intérieur de la zone d'exclusion du fluide qui est à l'extérieur, de façon que le fluide à l'intérieur de la zone d'exclusion s'écoule vers la première sortie de fluide, et que le fluide à l'extérieur de la zone d'exclusion s'écoule vers la seconde sortie de fluide. Au moins un élément d'espacement peut être utilisé pour maintenir le séparateur en position fixe.
