<\/a><\/figure>A mobile wastewater treatment system built at NASA\u2019s Kennedy Space Center in Florida that can help prepare for long-duration missions on the Moon and Mars departed the spaceport and arrived at the University of North Dakota in Grand Forks. Graduate students at the university will test the technology under conditions designed to closely mimic the challenges of operating on another planetary surface.<\/p>\n
The Divergent Deployable Wastewater Treatment Facility is designed to turn crew wastewater into useful resources, which future explorers will need every day. At the University of North Dakota, teams will integrate this new wastewater system with the university\u2019s Integrated Lunar\/Martian Analog Habitat. Student operators and NASA researchers will study how the facility performs when connected to a habitat-like environment and exposed to the kinds of operational limits crews could face on another planet.<\/p>\n
\u201cNASA\u2019s Artemis program is laying the groundwork for a sustained human presence on the Moon, where habitats will need to operate far from the steady resupply chain that supports astronauts in partial gravity,\u201d said Luke Roberson, surface water systems lead within the Mars Campaign Office at NASA Kennedy. \u201cTo solve that challenge, we are developing the future of sustainable lunar surface systems to process wastewater into nutrient feedstocks for plants and biomanufacturing.\u201d<\/p>\n
How Treatment System Works<\/strong><\/h3>\nHoused inside an 8.5-by-24-foot trailer, the facility brings together three biological reactor systems, a vertical garden, water-polishing hardware, environmental monitoring, autonomous control software, and safety systems. The trailer was outfitted at NASA Kennedy<\/a> to function as a deployable laboratory and to travel between at least two simulation test sites as the technology matures.<\/p>\nUnlike wastewater systems on Earth, this facility keeps waste streams separate. That divergent approach is important for small crews, because wastewater from four to eight people can be highly concentrated. Urine, hygiene water, laundry water, fecal waste, and food waste each contain different levels of salts, solids, carbon, nitrogen, phosphorus, and other compounds. Treating them separately allows each stream to be processed by the reactor best suited for the job.<\/p>\n
To do that, the system uses three different bioreactors to treat waste streams. The Anaerobic Phototrophic Membrane Bioreactor processes fecal and food waste and converts it into a nutrient-rich wastewater that can support plant growth. The Suspended Aerobic Membrane Bioreactor processes urine and flush water. The Membrane Aerated Biological Reactor treats graywater from hygiene and laundry activities. Collectively, the bioreactors process nutrients to feed the facility\u2019s vertical garden and prepare the water for reuse. Inside that garden, crops will grow hydroponically, or without using soil, by using nutrient solutions derived from the bioreactors. Researchers will compare crop performance with plants grown using standard hydroponic nutrients.<\/p>\n

The setup will allow different waste streams to be separated at the source and sent to the correct treatment systems. In parallel, Ali Alshami\u2019s team is developing novel membrane-based separation technologies intended for future integration into the divergent wastewater facility to improve water recovery efficiency, contaminant rejection, and overall system resilience for long-duration habitation missions.<\/p>\n\u201cThe tests will help NASA evaluate real-world operation, crew training needs, system reliability, and how wastewater simulants compare with actual human metabolic waste in an analog mission environment,\u201d said Alshami.<\/p>\n
These efforts are focused on advancing compact, energy-efficient treatment approaches capable of handling complex wastewater streams generated in closed-loop extraterrestrial environments.<\/p>\n
\u201cThe testing campaign at the University of North Dakota supports the facility\u2019s technology maturation from laboratory-scale validation toward demonstration in a relevant Inflatable Lunar\/Martian Analog Habitat environment,\u201d said Pablo De Leon, professor and department chair of Space Studies at the University of North Dakota.<\/p>\n
Lessons learned could inform future higher-fidelity tests, including potential integration with NASA\u2019s next generation of yearlong simulated Mars missions via isolation analogs at the agency\u2019s Johnson Space Center in Houston.<\/p>\n
Technology for Making Moon Base Sustainable<\/strong><\/h3>\nThe work is part of NASA\u2019s broader Bioregenerative Life Support Systems effort, which is developing biological approaches to reduce dependence on Earth-supplied consumables. In future lunar or Martian habitats, systems like the wastewater treatment facility could help close life support loops by recovering water, recycling nutrients, supporting crop production, and reducing the amount of waste that must be stored or discarded. Further NASA research completed trade studies demonstrating how bioregenerative life support becomes more effective for space travel over current life support technologies.<\/p>\n
NASA researchers also are exploring how wastewater-recovered resources could support in-space manufacturing. One effort is studying how nutrient-rich water from bioregenerative wastewater systems could feed microbes that produce lactic acid, which can be turned into polylactic acid.

We want to help future crews live sustainably on the Moon, learn how to operate farther from Earth, and carry those lessons forward to Mars.\u201d<\/p>\n
