Computer automation of organic wastes “wet incineration” installation for closed ecosystems

Creation of long-term research bases on the Mars and other planets have been considered since 1960s. Diminishing time and labor spent on life-support issues are important in space missions as it allows increasing scientific and applied content of the mission. Physiochemical wastes treatment resulting to fertilizers for growing plants providing oxygen, water and food for crew is one of the processes required for crew operation in a closed volume. One of prospective candidates for the role of organic wastes treatment method for long-term space mission is “wet incineration” in hydrogen peroxide under alternating electric current. The method is relatively simple, compact, ecologically clean and efficient. Nitrogen left in forms relatively easily accessible for further treatment and inclusion into turnover processes is a significant advantage. The paper discusses features of the original organic wastes “wet incineration” installation automation in the transition from analog to digital control scheme of human exometabolites mineralization process applied to closed life-support systems. The work was aimed to embed “wet incineration” installation control system into information system of experimental model of space application bio technological life support systems to control the facility as whole entity. The control and monitoring programs were coded on Free Pascal and internal Arduino micro controller language. The original organic wastes “wet incineration” installation automatic control has been implemented. Process parameters data are saved in real time in formats comfortable for further mathematical processing in presence of such tasks.
