Aquaporins: Fighting the global water crisis using nature’s own filter

A new water-treatment technology used by astronauts aboard the International Space Station has the potential to provide clean water to millions of people worldwide. By using proteins called aquaporins, this system mimics the natural filtering abilities of human kidneys and plant roots to purify and recycle wastewater. With an increasing global water demand especially in remote locations where clean drinking water is not easily accessible, this technology has the potential to provide a more resource-efficient method of water purification not only in space, but here on Earth as well.

Aquaporine: Combattre la Crise Globale d'Eau en Utilisant le Filtre de la Nature

Une nouvelle technologie de traitement de l'eau utilisée par les astronautes à bord de la Station spatiale internationale pourrait fournir de l'eau propre à des millions de personnes dans le monde. En utilisant des protéines appelées aquaporines, ce système imite les capacités naturelles de filtration des reins humains et des racines des plantes pour purifier et recycler les eaux usées. Face à la demande mondiale croissante en eau, en particulier dans les régions reculées où l'eau potable n'est pas facilement accessible, cette technologie pourrait constituer une méthode de purification de l'eau plus économe en ressources, non seulement dans l'espace, mais aussi sur Terre.

Spin-off technologies for water

Have you ever considered how technological innovations from the space industry can benefit us here on Earth? You might be surprised to hear that non-space applications from space programmes are extensive.

Exploring the exciting potential of hyperspectral imaging for water quality monitoring

Harmful Algal Blooms occur when toxin-producing algae experience excessive growth within bodies of water. These blooms have the potential to cause detrimental effects on both aquatic and human health and can sometimes even cause death, depending on the type of algae involved (NIEHS, 2021). Thanks to the use of space-based remote sensing technology to monitor water quality conditions in coastal areas and drinking water reservoirs, nations are becoming more aware of the quality of their water.
