Abstract
A closed bioreactor for high organic carbon removal and ammonia conversion in high-strength wastes under microgravity conditions. Oxygen is provided to the bioreactor by diffusion through a non-porous hydrophobic membrane in a recirculation line, allowing a high rate of oxygen transfer while minimizing the opportunity for formation of bubbles. Operating the bioreactor as a closed unit at elevated pressures keeps the oxygen in the dissolved phase. The oxygen transfer within the reactor is thus much more efficient and uniform than in similar reactors having both a liquid and gaseous phase.
