This Final Report summarizes work performed and results obtained over the entire three year term of this project. It consists of two volumes. While this Final Report was being written, the Contracting Officer s Technical Representative for this project S.R. Mangum of Carderock NSWC asked us to describe application of this technology to purifying gray water on a future class of ships, the aircraft carrier presently designated as CVNX. Our response, lightly edited, is attached to this report as Appendix 1 of Volume I. Therein we present our best estimates of how this technology would actually look installed on ship, and how large and expensive it would be. Because the CVNX carrier will be a very large ship, an installation of maximum size is described a ship with a smaller crew would require an installation that is smaller and cheaper in proportion. This project advanced the state of the art sufficiently to warrant patent protection. A US Patent Application has been filed, and an identical international patent application that is, a PCT filing, from which subsequent applications in other countries may be derived. The entire patent application is attached to Volume I as Appendix 2. The reader may refer to it for detailed descriptions of the anodes, procedures for coating them, how needed chemicals are prepared, etc.. The detailed procedures for coating the anodes were in large part developed under this project. The physical design of the electrodes and the basic design of the cell pack predated this project. The patent application just filed contains a very detailed, up-to-date description of the technology, and it will be placed on open file at the US Patent Office a few months from now. For this reason, there is little in the way of technical information related to the technology itself that we consider sensitive or confidential at this time.
