The Japan Sewage Works Agency (JS) is actively utilizing new technologies to meet the diverse needs of local governments in the sewage business. To facilitate the smooth introduction of new technologies into contracted construction projects, we operate the "New Technology Introduction System." Recently, under this system, we have newly selected the following three technologies as New Technology Category I. Technology Name: Pretreatment Technology for OD Method Using Rotating Fiber Body Developer: JS, Toshiba Infrastructure Systems Corporation Recipient of Technology Selection: Toshiba Infrastructure Systems Corporation Selection Date: March 28, 2025, New Technology Category I Selection Overview: This is a type of biological membrane method using a three-dimensional mesh rotating fiber body, which reduces the organic load in sewage, thereby enhancing treatment capacity and achieving energy savings for the OD method pretreatment technology. *Note: Integrated into Toshiba Corporation (name change) from April 1, 2025.

The Japan Sewerage Business Association and our partner, Toshiba Infrastructure Systems Corporation, conducted joint research from April 2023 to March 2024 at the Ujiie Water Treatment Center (sewage treatment plant) in Sakura City, Tochigi Prefecture, using our wastewater treatment equipment for the purpose of energy conservation and increasing processing capacity.
