Water Treatment Membrane Division

We develop separation membrane for water treatment, which is being industrialized in many ways, such as: hollow membrane for wastewater treatment, 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:


  • Hiroshi Onishi (Professor) (*)
  • Hideto Matsuyama (Professor)
  • Akio Tada (Associate Professor)
  • Saeid Rajabzadeh (Associate Professor)
  • Yuji Sasaki (Assistant Professor)
  • Kecheng Guan (Assistant Professor)

Research Topics

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 development of desalination oriented FO Membrane processes.

Molecule-Scale Characterization Methods at Liquid-Solid Interfaces

We are proud of our international-compatible studies of liquid-solid interfaces with advanced scanning probes, atomic force microscopy and electrochemical microscopy. Collaboration with foreign researchers and students are welcome in broad research area including applied chemistry, physics, geoscience, materials and mechanical engineering.
