40KHZ 100W Digital Ultrasonic Algae Control Sensor Ultrasound Effective Algae Removal Transducer 

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.Principle of removing algae by ultrasonic
When the high frequency vibration of power ultrasonic transducer acts into water, it will produce the following effects:
Mechanical effect: ultrasonic wave causes mechanical vibration of related objects in the process of propagation.
Thermal effect: High frequency vibration can cause the medium temperature to rise and the vibration energy is converted into heat energy.
Cavitation effect: High frequency vibration in liquid cause alternate expansion and contraction of liquid medium, produces the positive and negative pressure alternately change, when the liquid will be torn, and local vacuum micro-bubble nucleus will be generated. Micro-bubble nucleus expand, close and oscillate instantaneously with the action of ultrasound. At a certain energy threshold value, the micro-bubble collapses and generates a shock wave of up to 1000 atmospheres and micro-jets in an instant.
Pyrolysis and free radical effects: Water vapor produced by micro-bubble nucleus splits and chains at high temperature and high pressure to produce free radical OH. When the bubbles collapse, OH go into the water, OH is a super oxidant. For organic substance in ultrasonic field, including important life macro molecule substance such as protein and nucleic acid, chemical reactions can take place rapidly under the action of free radicals. Generally speaking, hydrophobic and volatile organic compounds can enter the cavitation bubble for pyrolysis; hydrophobic and volatile organic compounds can oxidize with OH at the gas -liquid interface of the cavatation bubble or in aqueous solution.

The ultra-sonic wave device system releases ultra sonic wave, which creates a sudden hotpot, with high temperature and high pressure, after a series of power cycle, like oscillation, expansion, compression and collapse. Several seconds later, the hotpot cooled instantly, with a strong shock wave, which generates an extreme physical environment for organism and alga. Alga’s cell membrane broke down at this specific frequency of ultra-sonic wave, and finally decline and disappear.
