| Abstract: | Silicone rubber hollow fiber was able to enrich the oxygen concentration in air by about 30%, and oxygen was transferred sufficiently from the membrane to water. When an aeration tank was filled with hollow fiber to up to 10% of its volume, the oxygen utilization rate, Rr, was about seven times as much as the value in the standard activated sludge method. It is suggested that there is some possibility of improving the efficiency of aerobic wastewater treatment by using this system. |
