Lecturer, Faculty of Integrated Technologies
Dr Norazanita is currently a lecturer at Faculty of Integrated Technologies (FIT) teaching both Systems and Chemical and Process Engineering modules. She graduated with PhD at Loughborough University, United Kingdom in 2015. She studied both her Degree and Masters at the same University from 2006-2010. Took a year break to gain experience in working life at Energy Department at Prime Minister's Office as Project Officer. She decided to pursue her study at PhD degree under Ministry of Education's Scholarship in 2011.
Dr Norazanita's PhD research was focused on developing a portable membrane-based water purification system for natural disasters (especially floods) in developing countries. She emphasized on the latest technology at purifying contaminated water i.e. using membrane separation technology. As more than 90% disasters happen naturally, 95% of the fatalities happened in the developing countries specifically Asia, the most vulnerable regions affected by disasters. In the wake of disasters, the standard treatment for clean water production may not be accessible or fully functional. Over the last decade membrane technology has been considered to be one of the most effective techniques to treat contaminated water in emergency situations with high productivity due to several reasons. These techniques offer simple operation conditions in comparison to conventional techniques such as slow sand filtration, filtration/disinfection, and flocculation/chlorination. Moreover these techniques are cost effective, safe and feasible to operate. The idea of operating such device without electrical power supply and chemicals would be advantageous in the events of disasters, while waiting for aid to arrive.
Her current research interests include performance improvement of circular cross flow membrane filtration for purification of drinking water through process modelling of the hydrodynamic conditions. Also to further explore the design of membrane based point of use water treatment system (PoUWTS) which could be used at home and for leisure activities. Her research expands to water pollution and management such as non-point pollution and its impacts on water quality in Brunei Darussalam. It has been reported that Brunei Darussalam has not yet been able to control its non-point source of pollution especially from residential area along Brunei River. As Brunei moves towards Industrial Revolution 4.0 and with increasing importance of Internet of Things (IoT), her research interest has expanded to IoT for monitoring water quality which will offer constant real-time online monitoring as feedback to users.
Membrane Separation Technology, Water Purification Techniques, Environmental pollution, water and waste water management
Abstract: Problems with water quality normally link with increased pollutants as a result of human activities. River has constant interaction with its physical environment as well as the climate and human factors. There are two categories of water pollution sources: point and non-point sources. Point source pollution is due to direct discharge from waste water treatment and industrial plants, whereas non-point sources that come from other sources and locations (e.g. residential area). Brunei has 4 major rivers with Brunei Muara district being the most populated district. Hence Brunei river in Brunei Muara district could well be affected with pollutants. Hence it is the focus of this research project to focus on non-point pollution along the residential area of Brunei river and its impact on water quality.
Abstract: Membrane fouling is a major impediment to membrane efficiency and it results in the reduction of membrane performance. Despite the vast efforts to reduce the effect of membrane fouling by improving membrane properties, optimizing operating conditions and pre-treatment of feed water, fouling is unavoidable. Improved hydrodynamic conditions such as manipulating shear rates on membrane surfaces, improved design of the membrane systems, and induced flow instabilities are other useful methods in overcoming membrane fouling and concentration polarization. These methods would be further studied using both experimental and computational methods in a circular cross flow membrane filtration.
Abstract: In 2010, it was reported that BND3.9 million had been allocated to clean up Sungai Brunei. As of 2015, Brunei has not yet been able to control its non-point source of pollution, which carries around 30 to 40 per cent of total pollutant load. The main objectives of the project are to develop IoT systems to monitor the water quality of Sungai Brunei and its tributaries, and to propose mitigation measures to minimize the impact of non-point source of pollution in Sungai Brunei. In order to address these issues, four main tributaries which eventually leads to Sungai Brunei are investigated: Sungai Kedayan, Sungai Menglait, Sungai Tungkadeh, and Sungai Rimba. These areas are heavily associated with steady increase in population growth and economic development which indirectly affecting the overall water quality along these rivers. Each river will have its own proposed sites where IoT systems will be placed and monitored directly. The multi-disiplinary research project will require: measurement of water quality parameters such as pH, temperature, turbidity, conductivity, dissolved oxygen and fecal coliform, development of IoT systems such as sensors, and offer constant real-time online monitoring as feedback to users. This research project will be a subsidiary to our initial project proposal (FIC Research Grant applied) on “non-point pollution and its impact on water quality of Sungai Brunei”. With results gathered from IoT systems and manual data gathering and analyses (from initial project proposal: non-point pollution and its impact on water quality of Sungai Brunei), it is hoped that Sungai Brunei and its tributaries will have its reliable water quality monitoring systems and can assist goverment agencies such as Jastre in proposing preventive measures to preserve the water quality of our Sungai Brunei for the present and future generations. This work will hence add value to the Environmental Impact Assessment (EIA) work at Sungai Brunei.
