Biological Treatment of Wastewater Using Ultrasonic Waves

A combination of methods related to microbubbles and high-frequency, low-power ultrasound methods for lateral flow in industrial water systems has been introduced, which has shown good results in controlling bacterial and algae levels.Through the tense environment created by ultrasonic waves, the population of suspended particulate matter in water and plankton can be controlled. (programmed cell death method).In addition, in systems treated with ultrasonic waves, instability and decrease in biofilm can be observed, which may be due to the starvation resulting from the absence of connecting cations in the biofilm.Additionally, one of the biggest challenges in the water and wastewater industries is the disposal of sludge from the final stages of wastewater treatment, which is a costly and time-consuming process. Various methods based on mechanical, chemical, biological, and other phenomena are used to expedite this process. Among these, wastewater treatment methods are widely used in many countries due to its significant advantages
