title: The effects of the frequency and waveform of the activating current on physicochemical oxidation of organic wastes.
abstract: The study describes the process of organic waste mineralization in an H2O2 aqueous medium activated by alternating current, which is intended to enhance the cycling rates in closed life support systems (CLSS) for space missions. The focus of this study is the relationship between the energy consumption and duration of the process and oxidation level of organic wastes on the one hand and the frequency and waveform of the electric current activating H2O2 decomposition, on the other. Energy consumption and duration of the complete waste mineralization process have been reduced by about 17-18%. A physical model of the process and the applicability of the results for both space and terrestrial purposes have been discussed.
