Research Topic: Development of A Membrane Bioreactor System for the Treatment of Polluted Surface Water

This research tries to develop attached growth MBR system for polluted surface water treatment. In this study, polyvinyl alcohol gel (PVA-Gel) and aquaporousgel (APG) as novel bio-carriers will be selected by pre-test. Membrane filtration and attached growth MBR will be set in parallel to analyze the removal performance. Parallel attached growth MBR with varying HRT and filling ratio will be set to optimize operation condition. Optimized system, effluent disinfection byproducts formation potential and bio-stability will be studied. Membrane module characterization and fouling layer analyze will be studied. The removal kinetic and kinetic coefficients of optimized system will be studied.

Research Topic: Evaluation of Technology Advancement and Performance Efficiency in Drinking Water Treatment and Distribution System: A Comparative Study in South Korea, Thailand and Lao PDR

This study will carry out three main aspects of drinking water supply system in three countries of different economies, namely South Korea, Thailand and Lao PDR.

The first aspect deals with the technology development trajectory in water treatment from three countries. This will be explained in detail with the timeline of what, why and how of the technology development and innovations in water treatment system. It is expected to explore the possibilities of suitable technology transfer across these three countries by evaluating and comparing the current water treatment systems of each country.

The second aspect is to assess and evaluate the performance of water distribution system. Performance improvement in the distribution system is more important for increasing end user (quality and cost) satisfaction on tap water. This study will however focus on the performance of energy use in the water distribution system, because the distribution network requires energy for conveyance from water treatment plant to storage tank or household by pumping.

The third aspect will cover the subject of green supply-chain management (GSCM) in the drinking water sector. The study will trace the overall economic and environmental performance of the water supply chain. The detailed cases on tap water and bottled water will showcase the greening potential of the water supply industries, best identified at every value-chain stages from water extraction, storage, treatment process, and distribution.
