Abstract

Water shortage is a global challenge. Desalination process is always required to remove salt from seawater. Reverse osmosis (RO) technology is a typical industrial process in desalination, but high energy consumption and fouling are key issues associated with RO operation. We recently developed various RO thin film composite (TFC) membranes by incorporating series of functional nanoparticles to the thin film layers of the RO membranes to produce nanostructured TFC membranes. The fabricated TFC-RO membranes were able to alter surface hydrophobicity and increase water permeability. On the other hand, forward osmosis (FO) technique has attracted extensive attention in recent years due to the advent of novel draw materials. Comparing with traditional RO process, FO process is more energy-effective. Our group has contributed significantly to the application of smart microgels as novel draw materials for FO desalination, where water-adsorption and de-watering could be easily achieved with low energy consumption by changing external triggers. It is expected more economic desalination techniques will be developed to benefit the societal challenging topic of fresh water supply.

Bibliography

Sheng Dai received his Bachelor degree from Zhejiang University (China), and Masters and PhD degrees from Nanyang Technological University (Singapore). After that, he worked as a postdoc research fellow at McMaster University, University of Alberta and University of Toronto under the support of NSERC (Canada) and NIH (USA). He joined the University of Adelaide (Australia) as a Senior Lecturer in 2009 and was promoted to an Associate Professor in 2012. In 2017, he took the Chair of Chemical Engineering, Deputy Head of School of Engineering and Head of Biosystems Group at Newcastle University (UK). Recently, he moved to Brunel University London as the founding Head of Department for Chemical Engineering. Sheng’s research
