| Abstract |
The purpose of the study was two-fold: first, to define the efficiency of various methods of cleaning fine pore diffusers and, second, to develop a methodology that could be used to evaluate the efficiency of the cleaning techniques. Dirty fine pore domes from the North Texas Municipal Water District were cleaned by a variety of techniques, and the improvement in oxygen transfer efficiency was measured. The domes were reinstalled in the aeration tanks and withdrawn at various time intervals thereafter. The deterioration in oxygen transfer efficiency was then noted. The cleaning techniques were repeated, and the improvement in transfer was recorded. |
