1 Energy-saving Approaches (See Figure 1) 2 Equipment and Facilities 2.1 Aerator The performance of the aerator was tested through experiments. The test results showed that the total oxygen transfer coefficient decreased 57% on average and increased with the aeration. As the old aeration device fouling serious, resulting in a single aerator gas supply decreased turbulence
