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. |

| Assoc Prof Massimo Pica Ciamarra | We are interested in understanding the physics of disordered many-particle systems via statistical mechanics tools and numerical simulations, which is arguably one of the most pressing needs in material science. Such an understanding is crucial to 1) design atomic or polymeric disordered materials with specific mechanical and rheological properties; 2) rationalize natural catastrophic events, such as earthquakes and avalanches; 3) improve the many industrial products and processes handling particulate media, from the food to the pharmaceutical and the electronic industry. The main difficulty is the developing of a theoretical framework connecting the macroscopic and the microscopic scales in the presence of disorder. Some topics of specific interest are:
1. glass transition
2. suspensions of soft deformable particles, e.g. microgels
3. liquid with density anomalies
4. rheological properties of disordered particulate systems, with applications to earthquakes
5. pattern formation in driven particulate systems, e.g. segregation
6. transport properties in disordered media |
| 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 publications are titled "Industrial Wastewater Treatment" (Imperial College Press) and "Wetlands for Tropical Applications" (Imperial College Press).
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). |

| Prof Stefan Wuertz | The basic task of an environmental engineer engaged in water quality management is the maintenance of adequate water supplies for the benefit of society. Aspects of both quality and quantity of water are very much at the forefront of today’s challenges in the face of a changing climate and diminishing resources. For example, being able to determine the origins of fecal pollution in urban waterways is becoming increasingly important as we aim to respond to natural and man-made disasters. Knowledge about the sources of microbial and other contaminants can help mitigate their impacts and facilitate risk assessment of exposure to drinking and recreational waters, Similarly, treatment of used water requires increasingly stringent and innovative technologies that build on the discovery and exploitation of microbiological processes, such as those found in the N and P cycle.
Through the development of new tools in the life sciences it has become possible to complete whole genome analyses of microorganisms in a short period of time. Bioinformatics tools, while lagging behind in the development of technical solutions to fast and” deep” sequencing technology, are being readied to accommodate the growing need of data compilation, management and interpretation. Across the developed world engineers have begun to interact with their counterparts in the natural sciences in a search for knowledge that can result in new technology for the treatment of water and used water.
As a researcher and educator steeped in both environmental engineering and life sciences disciplines, I strongly believe in studying fundamental biological and physico-chemical processes to develop new technology that is sustainable and market-ready in the long term. My vision for the School of Civil and Environmental Engineering (CEE) along with the Singapore Center on Environmental Life Sciences Engineering (SCELSE) is to train students in practical and theoretical aspects of what can truly be called environmental life sciences engineering (a new discipline coined by the directorate of SCELSE) and provide guidance to academic colleagues and postgraduate researchers at NTU.
In specific terms, my research program involves the following three thrusts:
a) Fundamental studies of biofilms and microbial communities in natural and engineered systems
The emphasis is on a complete spatial and temporal description of microbial aggregates involved in the removal of chemical constituents-of-concern using advanced imaging and pyrosequencing techniques.
b) Optimizing bioreactor treatment strategies
As chemical analytical techniques become more sophisticated, so does our knowledge about the occurrence of specific contaminants in the environment. The field of wastewater treatment has historically been based on general treatment goals using empirically derived methods in design. However, this system often fails to deliver specific treatment goals such as degradation of a specific contaminant without affecting general treatment performance. An ever increasing number of chemical contaminants are being detected in treated used water effluent and in biosolids. Therefore, knowledge of the removal mechanisms of specific contaminants as well as an in-depth understanding of overall microbial community dynamics and expression of functional genes in a reactor is necessary.
c) Protecting Public Health in Singapore
For several years I have been working on the quantitative detection of pathogens in natural (e.g. storm) waters and biosolids using procedures based on the polymerase chain reaction (PCR). Much of this research is driven by the growing realization in the scientific and professional community that for a variety of reasons standard microbial indicators like E. coli, fecal coliforms and enterococci may be inadequate predictors of recent fecal contamination in recreational waters. |

| Prof Tan Kang Hai | A/P Tan's research interests include structural fire engineering, strut and tie modelling of reinforced concrete structures, progressive collapse analysis and testing of structures, finite element programs for heat transfer analysis and nonlinear structural analysis and evacuation modelling using cellular automata. |
| Assoc Prof Tan Soon Keat | Dr Tan's research interests include application of geographical information system (GIS) in water resources, numerical simulation of flow for hydraulics and coastal engineering applications. His current research projects include hydrodynamic consideration of mega underwater structures and application of wetland technologies in the removal of pharmaceutical products from wastewater streams.
Dr Tan specilaises in urban water management and has developed the catchment – drainage GIS map of NTU campus. The GIS map is designed to facilitate rainfall-runoff modeling as well as water quality modeling. While rainfall-runoff modelling is generally well-established, water quality modeling is not, especially in the estimate of the source concentration of the pollutants. Current research focus in the community is in the establishment of the total nitrogen (TN) and total phosphorous (TP) in rainwater runoff. The difficulty lies in the fact that TN and TP varies with time, space as well as the intensity of rainfall. Dr Tan has a PhD project on TN and TP as contaminant in rainwater runoff.
Removal of water-borne contaminant, particularly trace quantity of drugs and pharmaceutical products from waste-water streams is a challenge in the management of water resources, and in particular, raw water for water supply. A viable and feasible solution is to employ wetland technology as a means to remove these contaminants. Under the supervision of Dr Tan, a research team is carrying out a series of constructed wetlands experiments with raw water spiked with selected contaminants. The research work has produced meaningful results since its inception in 2009.
Currently Dr Tan is leading a research team to conduct research on the various hydrodynamics considerations for a mega underwater structure, looking at the effects of flow, wave and environmental loads on a single or group of surface protruding structures. The research team comprises 10 research fellows. The challenge of the project is that the structure is to be founded on the seabed, with living space on the seabed, or supported on legs or semi-submersible, and the columns also support a deck space above the water, making full use of the 3-dimensional space. The structure has to be of mega-size to make it economically viable. As such, the environmental loads, impact of flow and waves takes on a different dimension compared to a land-based structure or oil platforms. Of particular significance is the possibility of vortex-induced-vibrations, as well as trapping or building up of waves within the group of structures. Later research work includes selection of potential site for the construction of a pilot structure as well as the effects of such structure on seabed sedimentation, ecology as well as its impact on the environment. |
