28KHZ 50W PZT-4 Ultrasonic Algae Prevent Transducer Ultrasound Algae Removal And Control Sensor 

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.

There is an alternating cycle of positive and negative pressures in the propagation of ultrasonic waves in water. At the positive pressure phase, the water molecules are squeezed to increase the density of water, and the negative pressure phase causes the water molecules to be sparsely dispersed and the water density to decrease. When the amplitude is large enough, the average distance between water molecules in the negative pressure phase will exceed the critical molecular distance of water, causing the continuity of the water body to be destroyed and forming a cavitation nucleus. The cavitation nucleus rapidly expands to form cavitation bubbles, which are rapidly compressed or even collapsed in the subsequent positive pressure phase, which is the ultrasonic cavitation effect.
The pseudo-cavitations inside the algae cells cavitation under the action of ultrasonic waves, forming cavitation bubbles, and then the cavitation bubbles collapse. The shock wave and high temperature and high pressure caused by the collapse can destroy the active substances inside the algae cells, and also destroy the structure inside the cells and interfere with the synthesis of chlorophyll. At the same time, the free radicals generated can also oxidize the algal toxins released by cell rupture.
