  • Renewable and unutilized energy (biogas power generation, wind power, solar, small hydro-power, sewage heat source, etc.) seems to be suitable to install for the sewage treatment facilities. There are 357 sewage treatment plants in 2007. 17 plants among these have been operating for self-supporting energy by using solar power, small hydro-power and biogas in 2008. Newly built sewage treatment plant of 96,000 $m^3$/day for a newtown is expected to get up to energy consumption of 10 GWh/yr. If solar energy, small hydro-power and biogas-equipments were applied to the new treatment plant, self-supporting energy of the new sewage treatment plant will get up to 56.1%. As a results, about 2,379ton $CO_2$/yr $CO_2$ emission reduction can be expected by using renewable energy. These efforts for self-supporting energy will lead sewage treatment plant to new energy recycle center.

  • Recently, small hydropower attracts attention because of its clean renewable and abundant energy resources to develop. However, suitable turbine type is not normalized yet in the range of small hydropower and it is necessary to study for the effect ive turbine type. Moreover, relatively high manufacturing cost by the complex structure of the turbine is the highest barrier for developing the small hydropower turbine. Therefore, this study is trying not only, to classify the type of current operating turbines installed in the domestic power plants and turbines supplied in Japan by Japanese manufacturer but also, to examine the practical turbine type and installation site to extract the small hydropower energy effectively.
