The level of iron in silica sand determines its ultimate application in glass making. Iron levels range from 0.1% Fe 2 O 3 for the manufacture of amber and green glass, through 0.03% for clear glass and less than 0.015% for table ware. The sand studied had already been processed for the manufacture of container glass and flat glass and had an iron content in the …
Ultrasonic soil washing processes using organic solvents were investigated for the development of novel remediation technologies for persistent organic pollutants (POPs)- contaminated soils.
The ultrasonic washer can clean clothes more efficiently than traditional washing machines because it can clean deeper into the fabric. Additionally, because the washer does not require hot water or high-pressure cleaning, it is gentle on clothes, making it suitable for cleaning delicate fabrics. The ultrasonic washer also uses less water and ...

A Complete User Guide for Ultrasonic Cleaning. Ultrasonic cleaning is a process that uses high-frequency sound waves to remove dirt, grime, and other contaminants from the surface of an object. The process works by generating high-frequency sound waves in a cleaning solution, typically water, that cause microscopic bubbles to form and collapse.
Ultrasonic cleaning mechanism of oil-contaminated sand is predominantly mechanical and mechanical-induced, and cavitation is the main effect intended for sand cleaning reactor, as the collapsing bubble near a sand particle could remove oil adhering to the surface of the sand particle.
Ultrasonic cleaning and washing of surfaces. F.J. Fuchs, in Power Ultrasonics, 2015 19.1 Introduction. Ultrasonic cleaning uses high-frequency, high-intensity sound waves in a liquid to facilitate or enhance the removal of foreign contaminants from surfaces submerged in an ultrasonically activated liquid. Ultrasonic technology has more recently been used in a growing …

Ultrasonic cleaning uses high-frequency, high-intensity sound waves in a liquid to facilitate or enhance the removal of foreign contaminants from surfaces submerged in an ultrasonically activated liquid.
Ultrasonic cleaning machines use special transducers that are mounted to a diaphragm and then to the cleaning tank of a unit and immersed in water. The transducer vibrates rapidly, creating ultrasonic waves, usually between 20-kHz and 40-kHz, but sometimes as high as 1 MHz (known as megasonic technology). ...

The effect of ultrasound on the conventional mechanical soil-washing process was investigated. To determine the optimal frequency for maximum efficiency, tests were conducted with aluminum foils under four frequencies including 35, 72, 110, and 170 kHz. It is known that the physical effects generated during acoustic cavitation damage the foil by causing pits and holes. The …
