PURE, Jul-Sept 2017 - Article in the Public Utilities Board quarterly magazine featured three Diploma in Civil Engineering with Business students Koh Wee Chen, Ayu Surya Binte Zainuddin and Chin Ze Zhao. They discovered that the fibrous residue that remains after a stalk of sugarcane is juiced can be implemented in a used-water filtration system to remove organic contaminants. Using a hand-pump installed column, the trio conducted experiments to assess the ability of sugarcane residue to absorb organic contaminants such as dye. Their water solution won them the Sembcorp Water Innovation Medal at the Singapore Junior Water Prize 2017.
