This waste management process must be capable of treating the various wastes generated within Controlled Ecology Experiment Facilities (CEEF) and operate effectively in and environment in which carbon, oxygen, nitrogen, salts, and other important minerals, exit. The catalytic Wet Oxidation Process (W/O Process) is regarded to be the most feasible candidate process for such waste management. This paper clarifies the performance data and the design data of the actual device. By applying these comparison data, for example, water balance, insoluble part balance, organic part balance, and inorganic balance for CEEF, we were also able to confirm the usefulness and applicability of the actual Wet Oxidation Device.

This paper describes the system modification through the improvement of pulse air penetration into the DPF cell channels in respect to the development of a wall-flow type diesel particulate filter ( DPF ) system with reverse pulse air regeneration for diesel vehicles. In this system, regeneration becomes more difficult with low exhaust gas temperatures and increased DPF volume. The pressure increase in the DPF cell channels was monitored as a parameter of pulse air penetration when reverse pulse air was injected into the DPF. By maximizing the pressure increase, the pulse air injection system was modified. The modification includes various changes in the air pipe arrangement and the air injecting time. The ratio of the length to the diameter of the DPF was also evaluated in relation to the regeneration efficiency. In this study, the high aspect ratio, i.e. small diameter and long DPF, showed better regeneration efficiency.
