Industrial applications of high-intensity ultrasound

In the last two decades, an increasing interest of academy and industry in the development of enabling technologies for process intensification has been paid. The main bottle neck for scientists and engineers to apply non-conventional technologies at industrial levels, such as high-intensity ultrasound, is the scaling up. Power ultrasound is proving to be a front-runner and offers a wide range of profitable applications. Although most examples reported by patents and scientific literature are not yet an industrial reality, few applications are recognised as the best available techniques for big scale production. Eloquent examples are reviewed in this article
