Nov. 16th, 2019Technical Tour: Energy recovery & New technology

Place: Sendai Senen Sewage Treatment Plant
Biogas typically refers to a gas produced by the anaerobic digestion oforganic matter including manure, sewage sludge, municipal solid waste andother biodegradable waste. The biogas for electricity system of Senen sewage
treatment plant was implemented in 2018 with 7 electric generator installed.
The total electric generation and yearly generation is 350 kW and 1,880,000
kWh respectively, which could supply electricity consumption of 407
generations (4618 kWh/Year/household). The emission of CO2 can be reducedby 1040t-CO2/year.

・The biogas for electricity system in Senen sewage treatment plant
AnMBR and One-stage Anammox is a new technology to develop anenergy-positive innovative sewage treatment system integrating an anaerobic
membrane bioreactor (AnMBR) and anaerobic ammonium oxidation(Anammox) process. The pilot plant in Senen sewage treatment plant has aworking volumes of 20 L for the AnMBR and 7 L for One-stage Anammox
reactor and completed with a capacity of 20 m3/d after a 140-day operation.
