Water Oxidation Waste Management System for a CELSS -The State of the Art

抄録

Water oxidation, which is one of the most hopeful candidate for a waste management system for a CELSS (Closed-Ecological-Life-Support-System) , was classified into four groups based on its temperature and pressure condi- tions, that is, wet-oxidation, catalytic wet-oxidation and supercritical water oxidation (low temperature and high temperature). Advantages and disadvantages of each were reviewed from a CELSS' point of view. And each process proved to have its own issues. In order to overcome them, more efforts to find better operational conditions, better catalysts, better system configulation and so forth are needed. Resarch and development of elements of a water oxidation system such as a high pressure pump, a high pressure compressor, a liquid-solid separator and so on is also urgently needed to initiate for CELSS use.
