As part of its series of scientific activities aimed at enhancing knowledge and exchanging research experiences, the Department of medical physics at the Faculty of science organized a scientific seminar entitled “ultrasound technology in water and wastewater treatment”, delivered by Assistant Professor Dr. Marwan Zuhair Elias. The seminar dealt with the problem of increasing human activities and the spread of various chemical compounds in the surrounding environment, and the resulting change in the quality of Water Resources, which necessitated the development of many biological, chemical and physical processes for the treatment of domestic, industrial and agricultural wastewater, as well as drinking water treatment. The lecturer also reviewed the advanced oxidation Processes (AOPs) that have been developed to improve the efficiency of water treatment and reduce the levels of pollutants in it, highlighting ultrasound technology as one of these modern technologies. The seminar touched upon the classification of sound waves according to their frequencies into infrasound, Audible, and ultrasonic waves, explaining the role of ultrasound in water sterilization and pollutant treatment processes, as well as its use as an energy source in chemical reactions within the field of sonochemistry. The lecturer explained that this technique is capable of creating local conditions characterized by very high temperatures and pressures as a result of the acoustic cavitation phenomenon, which greatly enhances the speed of chemical reactions, and makes it a promising technique in the treatment of a wide spectrum of water pollutants. With our wishes to our esteemed employees to always shine and give.
