“…The worldwide annual consumption of CBZ is 1014 tons [4]. The effluents in different European wastewater treatment plants (WWTP) uncovered that more than 75% are not able to remove CBZ efficiently and the effluent concentrations are often reduced in the range of 0-10% only [5]. Concentrations of PhACs detected in European surface waters are usually in the range of several ng L À1 .…”

“…Furthermore, less dissolved gas is present at higher temperatures and higher intensities, and more cavitation bubbles may be formed. Braeutigam et al (2012), while investigating the degradation of carbamazepine in water by hydrodynamic-acoustic-cavitation, have found that the rate constant depends on the reaction temperature, and thus, an increase in temperature should lead to increased conversion. Reactions below the value of 25°C resulted in lower formation of cavitation bubbles, lower bubble density, higher collapse intensity, and lower rate constants.…”

Pharmaceuticals are one of the chemical groups largely used in health care, diagnosis aids, cure, treatment, and prevention of disease. Increasing production and use of pharmaceutical products has led to the entry of these products into the environment and eventual pollution. Several processes have been studied including the use of ultrasound for the removal of these pollutants from the aquatic environment. This review summarizes recent research advances dealing with the development of sonochemical technologies for the degradation of pharmaceutical organic pollutants. The review also includes the mechanism of sonochemical processes, the characteristics of irradiation sources, and the types of reactors used. Moreover, the important factors affecting the sonochemical oxidation efficiency are discussed, including the electrical power, frequency, and temperature. Finally, this paper discusses the recent applications of sonochemical processes on the degradation of pharmaceutical organic pollutants and suggests new research directions for the development of this promising technology.

“…When liquid passes through a constriction, such as orifice plates or venture tubes, the local pressure drops below the saturated vapor pressure of the liquid at the operating temperature [5,6]. This results in vaporization of the part liquid or escapes of the dissolved gas in liquid which can form bubbles stream or cavities [7]. The bubbles or cavities are transferred by the liquid and shrink and eventually collapse instantly when the ambient pressure increases, large amount of energies are released then.…”

Hydrodynamic cavitation can effectively remove organic pollutants and microorganisms from water. Organic compound degradation and water disinfection removal rate is related to reaction time and operating temperature. Removal rate can be improved by increasing the reaction time or raising the operating temperature. Under our experimental conditions, the removal rate of colority, COD and petroleum pollutants was 80.0%, 72.13% and 70.00%, respectively. In addition, Escherichia coli removal rate was higher than 99.99%. As a new water treatment process, hydrodynamic cavitation can be utilized alone or in combination with other water treatment processes, showing broad application prospects.
