Research Divisions
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:

Research Topics
Development of novel water treatment process based on forward osmosis

In recent years, a forward osmosis (FO) process has attracted attention as a novel water separation technic for a desalination process or a process for concentrating foods, beverages, food additives, and bioproducts. Our group developed the FO membranes with high ammonia rejection and the DS with thermo-responsible materials.
