Nano-material filters could cut cost of cleaning water
The cost of filtering and recycling water could be reduced in a few years' time due to a new material developed by Nanyang Technological University (NTU) and the Public Utilities Board (PUB).
This was revealed at an international water conference here, called the International Water Association Conference and Exhibition on Water and Wastewater Technologies.
The material that is being engineered by researchers from NTU and the PUB uses nanotechnology, which controls matter on a scale smaller than 1 micrometre, and is made up of nano-sized crystals.
And because the crystals are so tiny, they are able to capture a large amount of unwanted matter in the water.
