Assoc Prof Lim Teik Thye	Prof Lim's scope of research projects encompasses both practical application of environmental technologies for pollution control and investigation of the process fundamentals. His core areas of research interest focus on application of advanced oxidation processes for water and wastewater treatment, developing novel functional materials for water purification, and developing innovative subsurface remediation technologies. He has over the years developed a range of nanomaterials for treating organic and inorganic micropollutants in surface waters, industrial wastewaters, and groundwater. He has also worked on projects exploring innovative use of industrial wastes for various applications, such as construction, earthwork, and environmental preservation. His current research projects are as follows: Novel photocatalysts This research engineers a novel photocatalyst for enhancing photocatalytic redox processes under solar radiation to remove emerging contaminants in water. It leverages off the complementary strengths among environmental process engineering, materials engineering and advanced materials characterization to develop a new-generation photocatalyst system. The advanced photocatalyst is a composite of nitrogen-doped titania (N-TiO2) supported on the powdered activated carbon (AC), or N-TiO2/AC. The composite have dual functionality, exhibiting high adsorptive properties for a variety of organics and photoactivity under visible light. The synergistic properties of the N-TiO2/AC composite enables its on-site regeneration, producing zero waste stream. Selective nanoporous adsorbents The goal is to develop various functional nano-structured materials such as layered double hydroxides (LDHs), zeolites, calcium aluminosilicates and nanoporous carbons to selectively adsorb trace inorganic contaminants, organic contaminants, and biomolecules that are difficult to be sequestrated using conventional adsorbents. The materials, such as LDHs and zeolites, can also function as catalysts to remove recalcitrant contaminants in water and air. Several types of LDHs have been synthesized in our laboratory. The LDHs have been evaluated for sorption of Cr(VI), As(III), As(V), Se(VI), and other oxyanions found in groundwater, surface waters and industrial wastewaters. Removals of up to 99% of certain oxyanions are possible. Bimetallic zerovalent metal particles The research group has synthesized nano-scale, bimetallic particles such as Ni/Fe and Pd/Fe for catalytic reductive transformation of halogenated alkanes and haloaromatics. The transformation pathways for these contaminants have been established for different types of synthesized bimetallic particles, through kinetic and mechanistic examinations of the experimental findings. The effects of catalyst content and particle ageing on their reactivities are investigated. Aqueous matrix effect on the transformation kinetics has been also examined in order to understand the possible performance of these reactive particles in industrial wastewater and contaminated groundwater.

His research interest explores the symbiotic and synergistic possibilities between visual practice and logocentric discipline such as sociology and human geography by exploring notions of dimensionality in knowledge production, presentation and dissemination.
Prof Ng Wun Jern	NG WUN JERN's research interests are largely in the area of water and wastewater management. The focus of his efforts has been on investigations into water quality, treatment science, and development of treatment technologies. These investigations span the water quality spectrum - ranging from ultra-pure water to high strength and potentially inhibitory wastewaters. His research output may be found in some 400 publications. These include journal papers, conference presentations, book chapters and monographs, reports, and patents. His latest book publication is titled "Industrial Wastewater Treatment" (Imperial College Press). He is currently working with colleagues on a book on engineered wetlands in tropical applications and one on water reclamation. Current R&D interests revolve around effluent treatment and include dehalogenation under bioreductive conditions. Of particular interest are the chloro-compounds and dehalogenation under acidic conditions with biomass sculptured into granules. The interest in bioreductive (instead of bio-oxidative) processes stems from concern over energy costs and carbon footprints of treatment processes. Anaerobic processes are therefore of interest when used to manage strong wastewaters from industrial and agro-industrial sources. Current R&D interest focuses on thermophilic anaerobic processes and gas productivities and quality. Conceptually there is a shift from viewing the anaerobic process as a wastewater pretreatment device to one which is intended to recover energy from the wastewater. Extending this interest is the work on biosorption where sorption is used to concentrate carbonaceous material from low strength wastewaters prior to anaerobic degradation of the sorbent with gas recovery. This approach deviates from the conventional approach of using anaerobic processes such as the UASB or anaerobic filter to address low strength wastewaters. Laboratory studies typically use the cyclic process configuration although larger scale studies can be with the cyclic or continuous flow configuration. In aerobic treatment, there is interest in the MBR applied with granulated biomass. The interest is on biofouling mitigation using this modified biomass morphology. There is also interest in using the MBR and the concept of "back seeding" to achieve better nutrients removal and degradation of resistant organics (eg textile dyes).
