Croda Singapore partnered NTU spin-off NanoSun to build an advanced wastewater treatment plant in Jurong Island
Croda Singapore, the regional headquarters of global specialty chemicals leader Croda International, has partnered with NanoSun, a spin-off from Nanyang Technological University (NTU) Singapore, to construct an advanced wastewater treatment facility at its Seraya manufacturing site on Jurong Island. This collaboration follows a successful pilot under the Jurong Island Innovation Challenge (JIIC), an initiative by JTC and Enterprise Singapore, marking a significant transition from testing to full-scale implementation.
The upcoming plant aims to substantially reduce Croda's dependence on freshwater sources and lower carbon emissions by 25% compared to current industry standards. NanoSun's cutting-edge water purification technology, which incorporates a patented high-performance filtration membrane produced through a 3D-printing process infused with titanium dioxide particles, will be central to this initiative. This membrane boasts self-cleaning properties and is enhanced by a confined nano-bubble process that improves filtration efficiency. The nano-bubble technology generates ultra-fine gas bubbles, smaller than 200 nanometers, which remain suspended in water longer than regular bubbles, increasing the surface area for chemical reactions and aiding in the breakdown of stubborn pollutants.
Associate Professor Darren Sun, Co-founder of NanoSun and a faculty member at NTU’s School of Civil and Environmental Engineering (CEE) shares: “NanoSun’s technology is designed to turn industrial wastewater into a valuable resource. Our collaboration with Croda highlights how advanced filtration and nano-bubble tech can drive sustainability in industries. Looking ahead, we aim to expand this innovation to convert CO₂ into construction materials for Long Island’s land reclamation while also lowering costs for NEWater production.”
This collaboration underscores the potential of innovative technologies in revolutionizing wastewater management and promoting sustainable industrial practices.
