Zirconium, the 21st most abundant element in the world, is a stable and chemically innocuous metal. Nanoparticles of zirconium oxide, says Arup SenGupta, have adsorption properties that make them uniquely beneficial to human beings. They can remove four major toxins — arsenic, fluoride, phosphate and lead — from water.
When organic material from thawing permafrost is transported to the sea and breaks down in the seawater it contributes to a more rapid acidification of the Arctic Ocean, finds new research by scientists from Stockholm University and colleagues.
A research project underway at the University of Calgary aims to clean up oilsands tailing ponds by using native algae already found in them to do the job.
The research team behind ClimateEngine.org unveiled their commitment to expanding the web applications unique role in helping the nation address water issues during today’s White House Water Summit held in Washington, DC, in conjunction with the United Nations World Water Day. The Summit is focused on raising awareness of water issues and potential solutions in the United States, and to catalyze ideas and actions to help build a sustainable and secure water future through innovative science and technology.
Arizona State University today announced a five-year initiative, FutureH2O, to flip the global conversation about water on its head and focus on the abundance of water and how to create it instead of hand-wringing about scarcity.
Ice shelves, the floating extensions of the Antarctic and Greenland ice sheets, are not simply resting on the ocean waters: they rise, fall and bend with the tides. Ultimately, these oceanic motions impact the flow of ice coming from the glaciers that these ice shelves buttress. Ryan Walker and Christine Dow, researchers with the Cryospheric Sciences Laboratory at NASA Goddard Space Flight Center in Greenbelt, Maryland, recently spent more than a month doing fieldwork in Antarctica to study the influence of tidal movements on a small, little-studied ice shelf.
Arvia Technology is the winner of the Innovation Award at the Innovation Forum of the 10th Annual Water and Energy Exchange Global Conference in Portugal.
Renewable hydropower generated from desalination plants and other existing infrastructure would bring economic and environmental benefits to our biggest cities, according to new research from Griffith University.
A team of researchers from the Ben-Gurion University Zuckerberg Institute for Water Research, the BGU Department of Geological and Environmental Sciences, and the Israel Geological Survey have established that compared to seawater, saline groundwater obtained from coastal aquifers is a better water source for reverse osmosis (RO) desalination. The main reasons for this are the reduced pre-treatment costs and minimal membrane fouling. The research findings have been published in the Environmental Science & Technology journal.
Farmers in drought areas are especially concerned by this question. As fresh water resources become scarce, one option for water-conscious farmers is to water crops with treated wastewater.
