Focus Area 5: Urine and Air Separation - Two Phase Fluid Separator Technology
Scope and Objectives
NASA is seeking proposals under this focus area to advance the state-of-the-art (SOTA) of urine/air separator technology with the ability to integrate the technology demonstration into a contingency toilet should an unrecoverable failure occur. The contingency toilet architecture will use a urine collection interface with airflow for waste separation from the body, odor control, and a gas-liquid separator to allow the collected urine to be processed with the on-board urine processor. The entire system will be efficiently packaged to minimize the onboard volume but allow for maintenance by crew on ISS.
To sufficiently advance the SOTA, a proposed separator must be able to reliably and robustly provide sufficient separation over a variable flow rate and duration of urine. If needed, airflow may be provided by an external blower or fan. It must be efficient, minimize system power and cooling requirements, and be small enough in size to fit within the spacecraft. It must be robust and have a long life to minimize the crew system maintenance and the spares mass needed for a human space exploration mission.
Additionally, an advancement on the SOTA would meet or exceed the following:
Fluid interfaces: The Separator should provide degassed urine to a filtered line leading to an external container (ambient) or the ISS urine processing systems (
3 psi back pressure) Pretreat compatibility: The separator should accept air and urine mixed with approximately 3-5 mL of alternate pretreat concentrate (APC) made of 85% aqueous phosphoric acid and 6.2% chromium trioxide by mass as an oxidizer. Reference US Patent No. 9,878,928,B1 for more information. Airflow: Urine is collected from a funnel with an airflow of up to 250 (+-50) SLPM. Crew may throttle the airflow rate. An external separate blower may provide airflow. The proposed separator tech... - Documents:
