Evaluation of a Novel Ultrasonic Cleaning Technique for Fine-Pore Diffusers

Abstract

The main concern regarding the activated sludge process is the fouling phenomena on the fine-pore diffuser membranes, due to their impact on the aeration blower’s electricity requirement. Thus, the aim of this research was to assess the effect of chemical and ultrasonic cleaning techniques in fine-pore diffuser membranes used in the activated sludge process, in terms of the standard oxygen transfer efficiency (SOTE) and aeration energy requirements. According to the state of the art, the ultrasonic cleaning had not been tested in fine-pore diffusers. Chemical and ultrasonic cleaning techniques demonstrated a significant recovery percentage on SOTE (2.0 to 4.2% and 4.2 to 5.7%, respectively), as well as functional recovery in the Dynamic Wet Pressure (DWP) (4.9 to 19.5 and 6.2 to 15.8%, respectively). Finally, it was found that extrapolating from the results of tests on pilot-scale to real scale can potentially save 30% of the aeration energy.
