Wastewater Brine Dewatering Technology Assessment and Development Roadmap

Concentrated wastewater brines, produced by primary stage spacecraft water recovery systems, can be further processed to recover additional usable water supply. The Lunar Surface Systems Project at NASA-JSC identified brine dewatering technologies as a critical technology need. In response, the Exploration Life Support Office commissioned a study to summarize the technologies currently available, and recommend a development roadmap for future resources. This paper reviews some of the technologies under development within the government, in academia, and private industry, and outlines a proposed development strategy to meet technology needs for the Lunar Outpost.
