28KHZ 60W 110V or 220V Algae Removal Ultrasonic Algae Controller For Sterilizing Algae 

The ultrasonic algal transducer has the function of degradation of organic pollutants and algae and algae inhibition, its main mechanism is that water produces "cavitation effect" under the action of ultrasonic radiation. Water has undergone a series of dynamic cycle processes, such as alternating oscillations, dilatation, compression and collapse under the "cavitation effect", producing instantaneous and microcosmic. High temperature (> 5000K) and high pressure (> 5 * 107 Pa) form a hot spot (Hotopot). After a few microseconds, the hot spots are cooled instantaneously, with a strong shock wave and a micro jet that reaches 100m/s, which creates an extreme physical environment for organic and algae. The O-H bond of water is broken and hydrogen peroxide is generated, which opens up a chemical reaction channel, increases the chemical reaction speed, and degrades the pollutants in the water under the action of high temperature, high pressure and hydroxyl radical. The ultrasonic wave action on water body, the resonance effect of the algae, and the water passing through the specially designed ultrasonic transducer of the submerged water body to the water at a specific frequency. Water is a good conductor of sound waves. This high frequency wave is spread in water. It has little attenuation and can be worn far away. For example, the effective emission radius of a 220V80W ultrasonic device is 100 ~ 180m, and the effective emission angle is 180 degrees. Algal cells produce resonance under the specific frequency of ultrasound, which causes the cell membrane to crack, and the algae decay and disappear. At the same time, ultrasonic technology can also handle many kinds of bacteria, viruses and all fungi. Many hydroxyl radicals produced by ultrasonic wave can degrade algae secreted by algae, and do not cause two pollution, and have no toxic effects on other aquatic organisms and human beings.

Ultra-sonic wave is widely recognized and proven method of removing alga, degrading organic pollutant of water. It has advantages over other traditional alga-removing and inhibiting methods such as handmade remove alga. Ultrasonic algae
Ultra-sonic wave device is consisted of a launcher, float device, wire and control box.

Low-frequency ultrasonic wave:low-power & low-frequency ultrasonic wave has a strong control effect on blue-green algae which are the most harmful in the water,and has a good inhibitory effect on green algae and diatoms.The removal effect of the blue-green algae with frequecy of 20~40 kHz and power density of 0.2~0.5 W/cm2 was better than that of green algae and diatoms,and that of anabaena fischeri was better than thar of microcystis.
High-frequency ultrasonic wave:when the ultrasonic frequency is 50~80kHz,the concentration of tree radicals in the water reaches a peak,and the removal rate of microcystis in the water is the highest,which indicates that oxidation is more effective in the removal of microcystis.

With the increase of ultrasonic irradiation time, the effect of ultrasonic algae removal will also increase. After reaching a certain dose, the removal rate of algae will not change much. This is because the cavitation intensity generated by the fixed ultrasonic device under certain power and frequency radiation is constant, and the extended ultrasonic treatment time cannot change the ultrasonic cavitation intensity, so it should be reasonably controlled in terms of ultrasonic treatment time.
In addition, different treatment modes have different inhibitory effects on algae. Multi-frequency ultrasonic irradiation of algae can enhance the inhibition of algae. The higher the frequency of treatment.
