The Use of Ultrasound in the Treatment Process of Wastewater. A Reviuw
MetadataShow full item record
In this paper, different types of ultrasound devices for the treatment process of wastewater are presented. The use of ultrasound in treatment processes is a method of perspective, an alternative to conventional methods. This technique is based on the cavitation phenomenon that occurs in liquids at ultrasonic irradiation and it is used to enhance or ensure the processes of heat and mass transfer. Some of the main advantages of using ultrasound, namely low consumption of additional material or energy, are presented in this paper. The categories of the ultrasonic transmitters distinguished on the basis of the principle underlying the generation of acoustic waves are described.
