High Frequency Ultrasonic Liquid Processor For Ballast Water Treatment

Description

Ultrasonic Ballast Water Disinfection The ultrasonic treatment system has demonstrated to be effective in the killing of bacteria, plankton, and larger organisms. The ultrasonic disinfection of ballast water is a mechanical/ physical treatment, which avoids the dosing of any strong and expensive active chemicals into the ballast water. This ensures an ideal environmental acceptability combined with high biological effectiveness regarding the destruction and inactivation of plant and animal organisms and microorganisms in ballast water.

Principles of ultrasonic sewage treatment

1. Cavitation effect: The high-frequency vibration generated by the ultrasonic transducer is transmitted through the liquid, causing the periodic expansion and collapse of tiny bubbles in the liquid. This phenomenon is called the cavitation effect. The collapse of cavitation bubbles releases huge energy and local high temperature, generating strong shear force and liquid flow shock waves. These energies can effectively decompose pollutants such as organic matter, grease, cells, etc. in the water.

2. Destroy the structure of pollutants: The high-energy shock waves and high-temperature effects generated by ultrasound can destroy the molecular structure of pollutants in the water, causing them to decompose or crack. For example, organic matter such as grease, dyes, pesticides, etc. will undergo chemical reactions or physical changes under the action of ultrasound, making them easier to decompose or remove.

3. Enhance flocculation: Under the action of ultrasound, suspended matter, colloidal particles, etc. in the water will produce strong impact and aggregation, enhancing the interaction between particles, thereby prompting them to aggregate to form larger flocs, which are convenient for subsequent sedimentation or filtration removal.

4. Promote chemical reactions: Ultrasonic waves can accelerate chemical reactions in water by providing local high temperature, high pressure and energy. For example, in the sewage treatment process, ultrasound can promote the oxidation and reduction reactions of chlorides and organic matter, increase the reaction rate, and enhance the sewage treatment effect.

5. Decomposition of toxic substances: Ultrasonic waves can decompose some toxic and harmful substances in water, such as organic solvents, pesticide residues, etc., thereby reducing the degree of water pollution. Ultrasonic treatment can also reduce the activity of certain microorganisms and inhibit their growth.
