Separation technology is at the heart of water purification, sewage treatment, and reclaiming materials, as well as numerous basic industrial processes. Membranes are used to separate out the smallest nanoscale particles, and even molecules and metal ions. A new type of membrane...

Scientists at NASA's Glenn Research Center have developed a unique water purification method that can be used for water recycling or point-of-use applications. Originally developed as a means to recycle water in space, this technology has applications in industrial water treatment, water...

Malawi has not been spared from the severe impacts of climate change. In the past two decades, Malawi has experienced a number of adverse climatic hazards, the most serious being dry spells, seasonal droughts, intense and unpredictable rainfall, riverine floods, and flash floods. Some of these, especially droughts and...

Innovators at NASA's Johnson Space Center have developed a filtration device to eliminate contaminants from water supplies. Originally developed to purify waste-water for reuse aboard the International Space Station, the innovation is applicable to numerous situations on Earth where there is a need to...

Various species of algae are known to produce valuable products ranging from food to fertilizer to biofuels. Methods have been developed for producing biofuels by processing algae and other micro-organisms that grow in aquatic environments, but the largescale commercial...

Effective recovery of potable water from various streams and sources of wastewater, seawater, or contaminated water is a significant task for securing existence of human beings in space, terrestrial, and marine environments. Efficient purification of the wastewater is also a very...

As crewed space missions extend beyond low Earth orbit, the need to reliably recover potable water is critical. Aboard the International Space Station (ISS), the water is recycled from cabin humidity condensate, urine distillate, and hygiene wash wastes. In spacecraft cabin air environments,...

NASA uses a biocide to prevent contamination of astronaut drinking water with harmful microorganisms. Concerns have arisen over existing biocides — that they’re inadequately effective, and may have toxic side effects when consumed. New microbial control methods are a...

Advanced Sensor Technology for Algal Biotechnology (ASTAB) is an integrated package of water quality and algal physiology sensors designed to enable algae growers to increase significantly productivity and efficiency of their operations, optimize harvesting periods, and avoid losses of...

The ability to stabilize and treat patients on exploration missions will depend on access to needed consumables. Intravenous (IV) fluids have been identified as required consumables. A review of the Space Medicine Exploration Medical Condition List (SMEMCL) lists over 400 medical conditions that could present and...
