Study aimed to treat wastewater by ultrasonic bath at 25, 35 and 130 kHz by estimating biological, physical and chemical parameters. Ultrasound (US), nanoparticle (NP) or in combination (US + NP) may offer an attractive proposition in the area of water purification. The basic phenomena of US irradiation is that acoustic cavitation can affect a number of mechanical, acoustic, chemical and biological changes in wastewater. Such changes occur due to US or NP by generation of free radicals. Owing to US and NP treatment, the enhance level of ROS may generate in water samples, and disrupt the bacter...
