“…Applications such as the detection of fouling in equipment [32], membrane flux enhancement [55], airborne particulate reduction [64], and the inactivation of microbes [60] are not covered here. Similarly developments in the use of ultrasound for environmental remediation and treatment of sludge have been described elsewhere [48,66].…”

Ultrasonic processing in simple terms is the application of sound waves in the frequency range of 20 kHz-1 MHz which is above the range of human hearing. This review focuses on the applications of ultrasound to accelerate processes such as dehydration, drying, freezing and thawing, tenderization of meat, crystallization of lactose and fat and to improve processes such as cutting, extraction, emulsification, ageing of wines and esterification. The effect of ultrasound on physical properties such as viscosity, opacity, particle size and gel strength is also considered. We find that it is the physical effects of ultrasound that predominate in most applications considered to date. Ultrasound increases heat and mass transfer, disrupts aggregates and can break macromolecular chains.

“…A comb sensor with a piezopolymer (2.5 MHz) was developed to produce ultrasonic guided waves (Hay & Rose, 2003). It was applied to a stainless steel pipe and fouling was simulated using Crisco vegetable shortening at the pipe interior.…”

“…Though significant work has been done on ultrasonic/acoustic techniques for pipe fouling detection guided waves by Hay and Rose (2003), guided waves and acoustic impact by Lohr and Rose (2003), Lohr, Rose, and Tavossi (1999), normal beam and pulse-echo by Withers (1996) no application has yet been reported for PHE. Hay and Rose (2003), designed a new piezopolymer guided wave sensor aimed at detecting fouling on the inner surface of piping commonly used in the processing of dairy products. On other hand, Lohr and Rose (2003), investigated guided waves and acoustic impact for pipe fouling detection.…”
