Separation of solid-liquid suspensions with ultrasonic acoustic energy

A theoretical and experimental study was carried out to investigate the possibility of separating solid-liquid suspensions of water and talcum powder, as well as in a process cooling water system, by means of a standing ultrasonic acoustic wave. Separation was successfully achieved with suspensions of water and talcum powder. The separation of suspended solids from the process cooling water was unsuccessful owing to the extremely small sizes of the suspended solid particles.
