A water treatment start-up spun off from Nanyang Technological University (NTU) is making waves around the world.

The company recently secured $12 million in funding, and is now looking to raise a new round of funds to help it scale up.

NanoSun has developed a way to produce self-cleaning, 3D-printed microfiltration membranes.

These membranes last longer than conventional ones, and are also more efficient, allowing more water to be treated even with a smaller plant. The company's patented titanium dioxide nanotechnology also kills bacteria and breaks down material that clogs up conventional membranes.

NanoSun was founded in 2013 by Associate Professor Darren Sun of NTU's School of Civil and Environmental Engineering and Mr Wong Ann Chai, an adjunct professor at Nanyang Business School and a former investment banker.

The company developed its water-filter technologies in close collaboration with national water agency PUB.

NanoSun has expanded rapidly over the years - it started off doing small-scale projects, but has since moved into the big league.
