Led by Professor Taku Fujiwara of the Department of Agricultural Sciences, a joint development project involving Kochi University, the Kochi City Water and Sewerage Bureau, the Japan Sewage Works Agency, and Metawater Co., Ltd. was selected for the Ministry of Land, Infrastructure, Transport and Tourism’s Innovative Sewage Technology Demonstration Project (B-DASH Project). The resulting “Non-Aerated Circulating Water Treatment System” has received the “Director-General of the Industrial Technology and Environment Bureau, Ministry of Economy, Trade and Industry Award” at the 44th Excellent Environmental Equipment Awards.
This technology is an energy-saving water treatment method that treats sewage without using blowers for aeration by installing a facility consisting of a pre-filtration unit, a sprinkler-type carrier bed, and a final filtration unit within existing sewage treatment facilities. As a low-cost technology expected to reduce maintenance costs by decreasing sludge generation, its widespread adoption is anticipated in the future.
