The Tama River, the largest river in Tokyo, runs through Tokyo from west to east, flowing into Tokyo Bay. Since about half of the river flow in the middle of the course of the river is treated wastewater, quality of treated wastewater greatly affects the quality of the river water itself. Regional Sewerage Office, which controls the sewage system of Tama area, has adopted A2O-based facilities in some line of all the 7 plants over the area by April 2004.(Table 1) This abstract describes the performance of these A2O lines of 7 plants over several years(Table 2), “measures taken against inferior performance ” and “desirable A2O facilities.”
