Although the application of ultrasonic energy to generate or enhance various processes has been explored since the mid-20th century, the number of ultrasonic processes established at the industrial level has decreased.

Since the mid-20th century, people have begun to explore the application of ultrasonic energy in the process of production and quantity modification, but only a few ultrasonic processes have been established at the industrial level.

However, in the past decade, the interest in ultrasonic treatment has revived, especially in the industrial sector. Ultrasonic technology may be a clean and effective tool for improving traditional existing processes or developing innovative options for new processes. This seems to be the case in food industry, environment, pharmaceutical and chemical manufacturing, machinery, mining and other related departments, in which power ultrasound is becoming a new technology of process development.

However, in the past ten years, the attention to ultrasonic process has revived, especially industrial ultrasonic technology can be regarded as a clean and efficient tool to improve the existing traditional process or as an innovative choice to develop new processes. Power ultrasound seems to be a new technology developed in food industry, environment, medicine and chemical manufacturing, machinery and mining.

The main problem in applying high-intensity ultrasound to industrial processing is to design and develop an efficient power ultrasound system (generator and reactor), which can run successfully on a large scale and is especially suitable for each individual process.

The main problems that may occur in the application of high-intensity ultrasound in industrial processes are: how to design and develop an efficient power ultrasound system (including generators and reaction devices), and how to successfully deal with the large-scale operation of each unique process.

In the field of ultrasonic treatment in fluid medium, more specifically in gas, the development of stepped plate transducer and other power ge with large radiation surface has greatly promoted the realization of semi-industrial and industrial stages of some commercial applications in fields such as food and beverage industry (defoaming, drying, extraction, etc.), environment (air purification, sludge filtration, etc.), machinery and manufacturing technology (textile washing, paint manufacturing, etc.).

In the field of ultrasonic process in fluid medium, especially in gas, the development of large incident surface power ge such as stepped plate converter has effectively promoted the realization of commercial applications in several semi-industrial and industrial stages, including food and beverage industries (defoaming, drying, extraction, etc. ), environment (air purification, sludge filtration, etc. ), machinery and manufacturing technology (textile washing, paint manufacturing, etc. ).

The development of different cavitation reactors for liquid treatment in continuous flow is helpful to introduce the broad potential of sonochemistry into industry. Processes such as water and wastewater treatment, crystallization and soil remediation have been implemented in semi-industrial and/or industrial stages. Other individual advances in industries such as mining or energy are also worth mentioning.

People have developed different cavitation reactors to treat continuous flowing liquids, which just makes the industry realize the broad potential in the field of ultrasonic chemistry. Such as water supply and wastewater treatment, crystal formation, soil remediation, etc. It has been realized in semi-industrialization and industrialization stage. Other developments such as mining or energy were also mentioned.

The purpose of this paper is to summarize some recent progress in ultrasonic treatment, so as to show the present situation and development prospect of high-energy ultrasound as an innovative technology in many industrial sectors.

The purpose of this paper is to discuss the latest development of ultrasonic machining and show the development status and future prospect of high-power ultrasonic as an innovative technology in many industrial fields.
