METAWATER to Construct the Japan's First Water Treatment Facilities Where Intensive Solid-Liquid Separation Technology is Used as Alternative to Primary Sedimentation Tank
-- Adopting the Technology Demonstrated in the B-DASH Project* --
METAWATER Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Yasushi Nakamura; "METAWATER") is pleased to announce that the consortium represented by METAWATER has concluded a construction contract with Komatsu-shi, Ishikawa Prefecture, for "Renewal Project for Komatsu Chuo Wastewater Treatment Plant (Machinery Equipment)" and "Renewal Project for Komatsu Chuo Wastewater Treatment Plan (Electric Equipment)".
This project uses intensive solid-liquid separation technology as filtration technology to carry out the water treatment process as an alternative to primary sedimentation tanks, allowing more than 50 percent reduction in space requirements and reduction of inflow load to aeration tanks. In addition, the technology can also improve combined sewer overflow (CSO) in rainy weather by reducing the contamination load of river and sea by discharging increased sewage from rainy weather after filtration and disinfection. The adoption of this technology will eliminate the need to newly construct a large flood control reservoir for rainy weather used exclusively for improving CSO, leading to a substantial reduction in the construction cost. This technology is part of the technologies for which METAWATER and Japan Sewage Works Agency Joint Research organization conducted an experimental study in FY2011 and evaluated by experts as a contract research of National Institute for Land and Infrastructure Management in the demonstration project for innovative wastewater treatment technology (B-DASH project)* by Ministry of Land, Infrastructure, Transport and Tourism (MLIT). This is the first case example of introduction of the technology in Japan after the technology introduction guidelines were formulated by National Institute for Land and Infrastructure Management.
METAWATER will support sewerage infrastructure, which is essential for people's lives, by spreading this technology across the country.
* Breakthrough by Dynamic Approach in Sewage High Technology Project ("B-Dash project"): Demonstration project conducted by Ministry of Land, Infrastructure, Transport and Tourism (MLIT) with the aim of accelerating R&D of new technologies and their practical applications to enhance cost reduction in sewage works and the production of renewable energy, as well as facilitating the global presence of Japanese companies in their water business. B-DASH is the abbreviation of Breakthrough by Dynamic Approach in Sewage High Technology Project.
