dc.descriptionThe proceedings for the 2020 International Conference on Environmental Systems were published from July 31, 2020. The technical papers were not presented in person due to the inability to hold the event as scheduled in Lisbon, Portugal because of the COVID-19 global pandemic.en_US
dc.description.abstractMicroalgae-based photobioreactors (PBR) for Life Support Systems (LSS) are currently being investigated for future space missions such as a crewed base on a celestial body. Biological components can help reducing the required resupply mass by closing material mass flows with the help of regenerative elements. By means of photosynthesis, the microalgae use CO2, water, light and nutrients from provide oxygen and biomass for the astronauts. These capabilities could have synergies with Earth applications that tackle current problems and the developed technologies can be transferred. For example, a current worldwide discussed issue is the increased nitrate and phosphate pollution of ground water from agricultural waste waters. To investigate the potential use of a biological system based on the ability of the microalgae to extract and use nitrate and phosphate for the treatment of polluted ground water from agricultural applications, a scalable test stand is being developed. This test stand investigates the maximization of intake rates of nitrate and quantifies the produced biomass and oxygen. This paper describes the composition of the artificial waste water and the development of the test reactor. Parameters for process control are discussed. The illumination system, and the possibility of non-invasive process optimization and control via adaption of the illumination is presented. Automation strategies and upscaling possibilities are outlined. The relevance of such a system and possible applications for the development of a biological component for a LSS is discussed.
