The removal rate of 1,4-dioxane in a sewage treatment plant with an activated sludge system was examined. We estimated the removal rate of 1,4-dioxane by comparing 1,4-dioxane inflow into and outflow from the plant, in relation to the sewage retention time of the treatment system. The estimated removal rate (8.5%) was low. Volatilization by aeration tanks and transfer with dehydrated cake negligibly contributed to the removal of 1,4-dioxane. These findings indicate that almost all of the removal can be attributed to biodegradation in the aeration tank.
