How is biological wastewater filtered?
On Earth, biological wastewater is physically filtered by granular soil and purified as microbes in the soil break down urea, converting it to a form that plants can absorb and use to build new tissue. Wastewater also evaporates and returns as fresh rain water -- a natural form of distillation.

What is the purpose of filtration in space?
Innovators at NASA's Johnson Space Center have developed a filtration device to eliminate contaminants from water supplies. Originally developed to purify wastewater for reuse aboard the International Space Station, the innovation is applicable to numerous situations on Earth where there is a need to collect potable, medical-grade water from a contaminated water supply. The unique aspect of the technology is its use of acoustics rather than pressure to drive water through small-diameter carbon nanotubes. The invention requires less power than conventional filtration systems and is well-suited to a variety of water processing needs.

What is NASA's water treatment system?
NASA Kennedy Space Center (KSC) seeks to license its Water Remediation Treatment System to industry. The system utilizes an affordable media that is highly selective for ammonia, allowing large concentrations of ammonia in wastewater to be reduced to levels less than 1 ppm. Following treatment, the media is regenerated for reuse in the system and ammonia is captured as a by-product. Removing nitrogen pollutants, like ammonia, is a critical environmental issue. Nitrogen pollution is causing serious changes to aquatic ecosystems; the primary cause of which is insufficient municipal water filtration processes allowing nitrogen to seep into groundwater. NASAs Ammonia Recover System could be utilized in a multitude of ways to remove nitrogen from various wastewater sources. The technology could be incorporated into water treatment systems at various stages; water treatment, effluent polishing, resource reclamation, resource recycling, grey water treatment, etc.
