SBIR-STTR Award

The primary objective of this proposal is to determine the feasibility of manufacturing a potable water purification device containing mixed-bed, ion exchange, separatory matrix. The proposed device would be capable of producing water to 1 Megaohm conductivity with a minimal capacity of 1 gram of Sodium Chloride in a field setting. This device will also be capable of operating in any orientation without the generation of internal channels, while maintaining a uniformity of fluid flow through the separatory matrix. These objectives will be achieved through incorporation of state-of-the-art, proprietary designs into the proposed device. Sepratech has recently received a U.S. Patent for a design fulfilling substantially the same requirements as descri ed in SBIR solicitation A90-186 and referenced in Technical Report 8814 (AD-A207 411). The internal structure of analogous ion exh\change devices, currently manufactured by sepratech, eliminate the problems associated with separatory matrix swelling and constraction, i.e. matrix compaction and channel formation. These devices are equally functional in any orientation. The design also enables enhanced separatiory potential above that of traditional separatory columns while reducing the time required for separation. The devices are manufactured for clinical use, therefore, are manufactured aseptically and are easily sterilized by several methods

Benefits:
A separatory device in which the possiblity of channel formation were eliminated, while the uniformity of flow and potential flow rate were enhanced would provide advantages over existing purification or chromatographic technologies in any application based upon Ion Exchange or Affinity separation as well as Gel filitration.
