More than 50 percent of the world will face water stress or shortage by 2025! A United Nations’ World Water Development Report reveals this horrific future of the world. It is in California alone, water-demand could increase by 40 percent in this time frame!
Then worst sufferers would eventually be the poor and underdeveloped countries. What is needed as a solution is a cheaper or affordable way to purify polluted and saline waters, making them suitable for human use.
A new technology from the University of California, Los Angeles seems to be coming up with just the right solution at the right time — an efficient and comparatively inexpensive technique using nanotechnology!
Desalinating water using the new method — using a nanotechnology-made membrane – is also more energy efficient and potentially much less expensive, the essential factors needed to solve water stress in developing and poor countries.
Named – the UCLA membrane – is developed by civil and environmental engineer Eric Hoek and his team. It is designed to shuttle water molecules quickly, repelling all other particles at the same time.
