Abstract
Application
of sound waves is one of the novel techniques for the improvement of water
treatment process. In this study, various sound waves such as 1) ultrasonic
wave, 2) music box, and 3) windbell were irradiated to water and wastewater for
removing contaminants such as nitrate, phosphorus and BOD/COD. As a result, a
possibility of improvement of water and wastewater treatment process using
sound waves with various frequencies was proposed.
