Research summary
Wastewater treatment and resource recovery by using microorganisms and aquatic plants The purpose of our laboratory is to develop technology for wastewater treatment and resource recovery by exploiting the abilities of microorganisms and aquatic plants. (1)Design and control of the biological wastewater treatment process A variety of approaches are used, including the design and operation of the bioreactor, the gene analysis of the microbes, and mathematical models for removing persistent chemicals and toxicants. (2)Wastewater treatment and biomass production using constructed wetlands We are surveying the constructed wetlands for treating landfill leachate in Southeast Asia. We are also testing the approach of converting the plant biomass that grows in a constructed wetland into biofuels and biomaterials. (3) Environmental assessment for developing sustainable wastewater treatment processes By the introduction of a variety of energy-saving and energy-generating technologies, we are exploring the design of future sustainable wastewater treatment process.
