@SmartPlanet - We create a lot of wastewater in realms as diverse as cities, industrial processes and agricultural work. A promising new solution could make the process of cleaning it up much cheaper and less energy-intensive.
Decanoic acid, when heated, absorbs water but also leaves behind contaminants, which can then easily be skimmed away. Cooling the acid then releases the water, making it easy to reuse.
The biggest test will be to create a process that is cheaper than simply dumping the water, which is the most common method for dealing with wastewater.
