We are working in the development of a compact, low power water recycling device that can supply delicious drinking water which can be consumed safely and with peace of mind in order to help astronauts lead a healthy and comfortable life in space. This device uses electrolysis to decompose ammonia and organic matter, purifies the water using a reverse osmosis membrane, adds minerals to the water, and then sterilizes the water, thereby maintaining water quality. An online system for measuring TOC and harmful substances is also used to manage the water quality.
