Novel membrane distillation technology for desalination unveiled [News]
By Valerie Chang, Channel NewsAsia, 20 Aug 2012.
A group of researchers from Ngee Ann Polytechnic has created a sea water distillation system using a first-of-its-kind nanofibre-based membrane.
Called Distil, the system can produce up to more than 200 litres of desalinated water per hour or 5,000 litres per day.
Most membrane distillation systems work on the basis of water transfer, which may generate products that are not as pure.
But not these nanofibre-based membranes.
These “water-repelling” or what is scientifically known as hydrophobic membranes allow only pure water vapour to pass through.
The system even earned the team two patents – one for the novelty of the membrane, another for the highly-efficient process of its technology.
