Most of the research on sewerage  is about the treatment technology at the sewage treatment plant but, in our laboratory, we are studying the entire sewer system including the sewage pipes. Although the sewer system looks like a steady infrastructure, it faces difficulties such as a decline in business income and a deterioration of facilities due to the depopulation. Also, today's sewers may not have been optimized. It has been approximately 150 years since modern sewerage was born but looking at the avergae lifespan of the sewer pipe which is approximately 50 years, the sewer system is three generations young. In contrast to other technology being used today, what generation of smartphones do you use? Because the sewer has a long life, its change is slow and that is why there is still room for optimization.

Our laboratory is currently working on the development of technologies that will improve the quality of sewage as it flows through the sewer pipe. Normally, the sewer pipe was a device only for transporting sewage, but it has been found that it is possible to use it as a water purification device to some extent by devising it. By placing a sponge-like material (a microorganism carrier) as a microbe in the tube and by making the microorganism carrier contact sewage and air alternately as the flow rate of the sewage fluctuates, organic components in the sewage Promote the oxidative degradation of We utilize natural processes to enable water treatment with energy saving. If done well, the functions of the sewage treatment plant can be significantly simplified. Furthermore, if the sewage treatment plant can be constructed and operated inexpensively, it may be possible to distribute the sewage treatment plant and make it easier to reuse treated water and nutrients such as nitrogen phosphorus.

Would you like to study the mechanisms of society and the ability of microorganisms while learning about sewerage together?
