Introduction This paper is intended to give a brief and general overview about the possibilities that can be attributed to treatement and disinfection of industrial or service water with ultrasound the various In combination with UV light applications short US pre-treatment is useful and also provides cost-effectiveness: It could be observed The use of aluminium and iron salts or the , Tiehm A.

Thus, excess biogas production results in an Figure 5: Improved UV disinfection (density: 50 W/L) by ultrasonic pre-treatment (sonication time: 5 s, density: 80 W/L) to meet the W.
