Saving our shores and water

“Another project known as EWat by Dr Olivier Lefebvre, won the IES Prestigious Engineering Achievement Award 2019 at the World Engineers Summit in August. Targeting hard-to-treat industrial water, it is able to remove up to 99 per cent of impurities without producing any secondary waste, said Dr Lefebvre who has worked with industries such as chemical, electronics and farms, which produce very challenging wastewaters and sludge.

With emerging contaminants such as pharmaceuticals, pesticides and residues from a wide range of personal care and common everyday products finding their way into our water these days, Prof Hu and her team are also paying a lot of attention to this area of treatment. Working with French researchers, they have successfully turned biomass such as cut tree branches and leaves into activated carbon for removing emerging contaminants. They have also developed a novel ultraviolet advanced oxidation process (UV-AOP) to generate highly efficient oxidants for breaking down emerging organic contaminants. A pilot-testing system is in the works to further test and evaluate its long term performance.”
