Catalytic advanced oxidation processes (AOPs)
I have 15 years of research track records in redox technologies for surface water, wastewater and groundwater treatment. For the oxidation technologies, my research activities cover sulfate-radical based advanced oxidation process or SR-AOP (homogeneous and heterogeneous), UV-based AOP (homogeneous and heterogeneous), Fenton processes (heterogeneous), photocatalysis (heterogeneous), electrochemical oxidation, and sonochemical oxidation, and hybrid AOPs. On SR-AOP, my group has made significant contribution to the scientific community in terms of advancing the understanding of the mechanisms of the heterogeneous SR-AOP with metal oxides (monometallic oxide and bimetallic oxides) and carbonaceous materials as catalysts to activate peroxymonosulfate (PMS) and peroxydisulfate (PDS). We have discussed our works in our numerous scientific papers and 3 critical reviews in the top journals. Specifically, we have provided insights into the radical and non-radical reaction pathways associated with transformation and mineralization of a wide range of organic emerging micropollutants such as antibiotics, cytostatic drugs, bisphenol A and industrial chemicals. On the homogeneous SR-AOP, our group is among the leading contributor to post-formation mitigation strategy for controlling iodinated disinfection by-products such as iodinated trihalomethanes and iodoacids in RO water. Our group also developed composite catalytic materials which comprise mixed metal oxides, bimetallic oxides, and catalyst-nanocarbon composites that exhibit multifunctional properties such as combined catalysis, adsorption-promoted catalysis, “switchable” catalysis, etc. Our iron-based catalytic composites can function as Fenton catalyst, photo-Fenton catalyst and photocatalyst, such that their applications can be switched over the day/night cycle. When irradiated with sunlight, they trigger sunlight-driven photocatalytic redox degradation of organic pollutants without any chemical addition. The materials can be recovered from the treated water using magnet. We have also developed a hybrid TiO2-activated carbon composites, which can be used as solar-driven photocatalyst or solar-regenerable adsorbent. This invention has been approved for PCT filing as a recognition of our intellectual property.
Catalytic ceramic membrane for removing recalcitrant organics
Over the last 10 years, my group has advanced the research of coupling catalytic oxidation and membrane separation process. The synergistic processes were enabled through our catalytic ceramic membrane research. We developed three types of such hybrid membranes: (1) photocatalytic membrane, (2) catalytic sulfate-radical oxidation membrane, and (3) catalytic ozonation ceramic membrane. One of our inventions, Ag-decorated photocatalytic TiO2-coated alumina membrane, has three functionalities: antibacterial and antibiofouling property, photocatalytic activity, and separation function with membrane pore sizes down to 4 nm.

| 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, wastewater, and sludge and agri-wastes management, with recovery of useful materials and energy. The focus of his efforts has been on investigations into water quality, treatment science, and development of treatment technologies and systems. These investigations span the water quality spectrum - ranging from ultra-pure water to high strength and inhibitory wastewaters, and organic sludges to agri-wastes management for recovery of soil fertility and crop yields.
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 and slurries from industrial and agro-industrial sources. R&D interest is on hydrolysis, staged and phased anaerobic processes, process stability and kinetics, gas productivities and quality, and recovery of resources. Conceptually there is a shift from viewing the anaerobic process as a wastewater pretreatment device to one which is intended to recover resources.
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). Aerobic processes are also used to produce enzymes, phytohormones, and beneficial microbial consortia from horti-and agri-wastes.
NG now leads his own research group, the Environmental Bio-innovations Group (EBiG), which as its name would suggest has focus on solutions which can be applied on the issues faced in the region. While not limited to bioprocesses, there are more numerous such solutions with intention to achieving more sustainable and circular approaches. |

| 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. |

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, rainfall-runoff modeling as well as water quality modeling, flooding, drainage, urban response, climate change and future scenarios analysis. Managing surface water in terms of quantitative distribution, storage and transport, removal of water-borne contaminant, particularly trace quantity of drugs and pharmaceutical products from waste-water streams are challenges in the management of water resources, and in particular, supply of raw water in the face of climate change and rapid urbanisation. A viable and feasible solution is to employ wetland technology as a means to remove contaminants and management of peak runoff. 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 and highly cited publications since its inception in 2009.
Currently Dr Tan is leading research work on strategic development of coastal, urban scape and water resources, in response to climate change as well as developmental scenarios. |
