Water purification technology using fermented microorganisms in Ehime Prefecture


The water purification technology using microorganisms developed by Ehime Industrial Technology Center is very unusual in that it uses microorganisms used in fermented foods, such as yeast, lactic acid bacteria, and fermented soybeans. Conventional wastewater treatment uses specialized microorganisms to decompose specific pollutants, but this technology applies common food-grade microorganisms. In particular, the results of a demonstration conducted by the Yawatahama Kamaboko Cooperative Association in Ehime Prefecture confirmed the effectiveness of the system in reducing sludge and deodorizing wastewater, as well as the secondary effect of a 70-80% reduction in treatment costs. In addition, because the microorganisms are naturally present in the environment, effective water purification adapted to the local environment is possible without creating an additional environmental burden. As a community-based environmental technology, this technology is expected to be applied to o
ther regions and industries, serving as a model for sustainable purification systems.
