摘要：
In this study, we investigate the effect of ultrasound on the dewaterability of sewage sludge. The investigation involves laboratory experiments, which were conducted under a broad range of conditions, including energy levels of ultrasonic waves, treatment time, and pH. Results of the study show that ultrasound enhances. dewaterability significantly. The degree of enhancement varies with sonication energy, treatment time, and the amount of treated sludge.
