✦ Synopsis

The phenomena of cavitation which is associated with the formation, growth and the collapse of microbubbles, leads to the generation of very high pressures and temperatures locally, which can cause cellular damage. This paper explores the microbicidal effectiveness of cavitation for the disinfection of bore well water for potable use. Experiments performed in this study indicate that hydrodynamic cavitation is an energy efficient and economical technique compared to the other conventional non-chemical water treatment processes and cavitation was found to be a potential physical water disinfection technique for the production of potable water.

## Abstract In this investigation, a self‐made low pressure device (up to 100 psi) for creating hydrodynamic cavitation was optimized by using the Weissler reaction. Optimal upstream pressure for the reaction was obtained for a single line system (without bypass) as 29 psi. The effects of the centr
