ADVANCED LIFE SUPPORT: SOLID WASTES


While the use of bioreactors for the destruction of solid wastes is under investigation, physico-chemical methods are also currently receiving considerable attention. Supercritical Water Oxidation (SCWO) utilizes temperatures and pressures above the critical points of water to provide a very rigorous oxidation of suspended particulate matter. The properties of water change above the critical points; organics are solvated and salts precipitate from solution. Wet Oxidation processes utilize high temperatures and pressures, but which are below the critical points. Currently SCWO, catalytic Wet Oxidation, and Incineration are the primary physico-chemical methods under development. References to these and other processes follow.
