We develop separation membrane for water treatment, which is being industrialized in many ways, such as: hollow membrane to purify wastewater, reverse osmosis membrane for seawater desalination and separation membrane for industrial drainage percolation.
In water management performed by applying separation membrane, the phenomenon occurred when organic and inorganic particles, as well as microorganisms present in water are accumulated in the membrane's surface, known as "Membrane Fouling", becomes our main problem.
With this background, we perform research in the following subjects:

Development of a Control Technology for Membrane Fouling Generation Mechanisms
Through the systematical regulation of the impact produced by water quality from water source, material quality and structure of the separation membrane, we are formulating principles for the study of issues related with Membrane Fouling. Based on these principles, we want to optimize the operation leading to reduction of membrane fouling and to propose a plan to perform an optimal selection of separation membranes.
Production of High Functionality Water Treatment Membranes
We are performing research in production of porous membrane based on phase dissociation of macromolecular solutions, and development of novel water management membranes based on innovative methods.
Through fundamental research on these subjects we aim to make possible the generation of separation membranes with high functionality and permeability.
Development of Novel Water Treatment Processes
We are performing basic and applied research on systems whose core is water management using separation membranes. for example, the development of energy-saving water management processes using Forward Osmosis (FO), and the deveolpment of desalination oriented FO Membrane processes.
