This thesis centers on the development of water recovery systems (WRS) tailored for sustainable, long-duration space missions akin to those on the International Space Station (ISS). The main goal is to elevate system efficiency, reliability, and overall performance of water recovery system, with a focus on reducing dependence on Earth's resources. This effort is geared toward ensuring astronaut safety and strengthening the long-term sustainability of missions. Investigating the historical evolution and milestones of water recovery systems, the study meticulously examines the current ISS water treatment system, encompassing intricate components like the Low-Pressure Distiller, Condenser/Economizer, Electrical Heater, Reverse Osmosis Module, Resin Filter, and Activated Carbon Filter.
