Drinkable seawater not just a dream
Water shortages are unfortunately but unquestionably far too common. In countries all across the globe, people find themselves facing the constant threat of running out of clean water for drinking, cooking and washing. On top of this, demand for water is expected to rise by a third by 2030. But research is currently under way into how to use carbon nanotubes (one-atom thick cylinders of carbon) to desalinise sea water and make it suitable to drink, with the hope of meeting these demands more easily.
Using computer simulations, a team of professors have developed a technique based on the process of reverse osmosis. Up until now, reverse osmosis has been thought too expensive and inefficient to be a practical solution to sourcing clean water. However, with nanotechnology like CNTs, reverse osmosis on a large scale is looking like an ever more promising possibility.
Professor Jason Reese, leading the investigation, commented “While many questions still remain, the exciting potential of membranes of nanotubes to transform desalination and water purification processes is clear, and is a very real and progressive use of nanotechnology.”
The Water Delivery Company ensures that high-quality drinking water is readily available for all of us customers whenever they need it; with technological developments like Professor Reese’s, hopefully water availability will be something everyone in the world can soon rely upon.
