An Overview of the Application of Hydrodinamic Cavitation for the Intensification of Wastewater Treatment Applications: A Review

Dindar E

Cavitation is a specific phenomenon in a liquid if any changes occur in the pressure field over time and distance. The effects of cavitation have become very useful in supporting chemical processes in the environmental protection technologies, especially in technologies related to the decomposition of substances particularly harmful to humans and his immediate surroundings. Cavitation can be realized by alterations in the flow and pressure (hydrodynamic cavitation). In hydrodynamic cavitation, flow geometry is changed in such a way that the kinetic energy increases at the expense of local liquid pressure, which can make cavities depending on the vapor pressure of the liquid. Traditional treatment methods do not always produce the expected results. There exists a certain group of organic non-biodegradable pollutants, having toxic, mutagenic, or carcinogenic properties. In the current literature there are many studies related to hydrodinamic cavitation and the use of associated processes in water and effluent treatment technologies.
