Principle of ultrasonic algae removal
When the high-frequency vibration of the power ultrasonic transducer acts on the water, it will have the following effects:
Mechanical action: Ultrasonic waves cause mechanical vibration of related objects in the process of propagation.
Thermal effect: High-frequency vibration will cause the temperature of the medium to rise, and the vibration energy will be converted into heat energy.
Cavitation: High-frequency vibration in the liquid will cause the liquid medium to expand and contract alternately. When the liquid is torn, it will produce alternating positive and negative pressures, and will produce partial vacuum microbubble nuclei. The microbubble nucleus instantly expands, closes and oscillates under the action of ultrasound. Under a certain energy threshold, the microbubbles collapse and instantly generate shock waves and microjets up to 1000 atmospheres.
Pyrolysis and free radical action: The water vapor generated by the microbubble nucleus splits and forms chains under high temperature and high pressure, thereby generating free radical OH. When the bubbles burst, OH enters the water. OH is a super oxidant. For organic substances in the ultrasonic field, including important life macromolecular substances (such as proteins and nucleic acids), chemical reactions can occur quickly under the action of free radicals. Generally speaking, hydrophobic and volatile organic compounds can enter cavitation bubbles for pyrolysis. Hydrophobic and volatile organic compounds can be oxidized by OH at the gas-liquid interface of the vacuole or gaseous solution.
Application of aquatic biological insecticide and algae removal.
Studies have shown that ultrasound has an effect in water and can significantly resist the growth of algae under certain conditions.
Low-frequency ultrasound: Low-power and low-frequency ultrasound have a strong control effect on the most harmful cyanobacteria in the water, and have a good inhibitory effect on green algae and diatoms. Cyanobacteria with a frequency of 20-40 kHz and a power density of 0.2-0.5 W/cm2 are superior to green algae and diatoms, and Anabaena fischeri is superior to Microcystis.
High-frequency ultrasonic: When the ultrasonic frequency is 50~80kHz, the concentration of free radicals of trees in the water reaches the peak, and the removal rate of Microcystis in the water is the highest, indicating that oxidation is more effective in removing algae. Microcystis.
Operation mode: Intermittent work is more effective, working 10 to 15 times a day, and each time working for 5 to 15 minutes has a better inhibitory effect on algae.
Studies have shown that under certain conditions, ultrasound can also eliminate aquatic organisms in the sound field and kill their eggs and larvae.
Ultrasonic parameters: When the frequency is 20-30 kHz and the power density is 0.3-0.5 W/cm2, the repelling and killing effect on aquatic organisms, especially marine organisms, is obvious.
The processing time is 10-30 seconds.
The water temperature is preferably between 30¡ÆC and 45¡ÆC.
