Hyperfiltration as a method of recovering wash water in a spacecraft environment has been studied by various investigators. Recent laboratory investigations of a dynamically formed membrane consisting of hydrous Zr(IV) oxide covered with polyacrylic acid have shown promise for providing long term stable performance at pasteurization temperatures. A summary of the se recent investigations is presented along with a description of the development program planned to bring the dynamically formed membrane technology to hardware maturity. Key development areas that are addressed include the multi-tube hyperfiltration module, the high pressure pump, pressure controls, and the disposition of urea and ammonia.
