Abstract
Water Recovery System (WRS) is a key-technology for future manned space exploration. JAXA aims at the higher water recovery rate than the current ISS system with no consumable supplies in order to reduce water replenishment. This report summarize features of JAXA’s Water Recovery System, and describes technical challenges encountered. JAXA are planning on-orbit demonstration using a scale model JWRS (JEM Water Recovery System) for technical demonstration for future operational use. It will be launched in JFY2018 and be demonstrated in the Multi-purpose Small Payload Rack (MSPR/MSPR2) in JEM. JWRS is composed by three main units, cation exchange unit, electrolysis unit, and electrodialyzer unit. Main purpose of ISS demonstration is to verify effect of bubble behavior to its water recovery performance in microgravity. The updated system of JWRS is aimed to be used as a part of closed ECLSS for future exploration.
