Covalent organic materials with well-ordered porous microstructures could provide the membranes needed for technology to meet increasingly stringent environmental controls and be cost effective to produce.
The fast-rising number of desalination plants worldwide—now almost 16,000, with capacity concentrated in the Middle East and North Africa—quench a growing thirst for freshwater but create a salty dilemma as well: how to deal ...
Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of water scarcity, mostly in developing countries. Traditional reverse osmosis (R/O) desalination systems offer a solution but require ...
Currently, more than 300 million people around the world rely on desalinated water for part or all of their daily needs. That demand will only grow with larger populations and improved standards of living around the world.
A membrane made of porous carbon-fiber structures grown on a porous ceramic substrate is more efficient at filtering seawater than existing similar membranes.
Researchers at The University of Manchester's National Graphene Institute (NGI) have achieved a long-sought-after objective of electrically controlling water flow through membranes, as reported in Nature.
New research suggests there's a large untapped resource for many of the increasingly water-limited regions of the U.S. and around the world: brackish groundwater, which, in theory at least, would require much less energy ...
It is a plan as crazy as the situation is desperate—towing an iceberg from Antarctica to Cape Town to supply fresh water to a city in the grip of drought.
Marine research could soon be possible without the risk of polluting either the air or the ocean. It's thanks to a new ship design and feasibility study led by Sandia National Laboratories.
Will South Africa's second largest city dry up on August 19 of this year? By launching an official countdown, Cape Town City Council wished to highlight the impending cuts to domestic water supply for its more than 3.7 million ...
