High Effect Ultrasonic Underwater Equipment 100W 28K For Anti-fouling And Algal Removal
A low-power ultrasonic algae removal device, which includes: an ultrasonic signal generator for outputting ultrasonic electrical signals with a preset frequency; a power amplifier, which is electrically connected to the output end of the ultrasonic generator, for generating ultrasonic signals The ultrasonic electrical signal output by the power amplifier is power amplified; an ultrasonic transducer array placed underwater, the ultrasonic transducer array is used to convert the ultrasonic electrical signal amplified by the power amplifier into a mechanical vibration wave and radiate it into the water.
Our devices emit low-power ultrasound waves in the top water layer, generating a constant pressure cycle around the algal cells. This interferes with the algae’s buoyancy regulation, preventing them from accessing sunlight and nutrients. As a result, they can’t perform photosynthesis and sink to the bottom, where they decompose naturally without releasing harmful toxins. No aquatic organisms, animals, or humans are harmed in the process.
Ultrasonic algae killing has the characteristics of convenient operation, high efficiency, no pollution or reduced pollution. The mechanism of ultrasonic anti-algae killing and algae killing includes: destroying cell walls, destroying air cells, and destroying active enzymes. High-intensity ultrasound can destroy biological cell walls and cause intracellular substances to flow out. The special structure of algae cells is an air cell that accounts for 50% of the cell volume. The air cell controls the up and down movement of the algae cells. Shock waves, jets, and radiation pressure caused by ultrasound can destroy air cells. Water is a good conductor of sound waves. This high-frequency wave spreads in the water with little attenuation and can travel far. The algae cells resonate under the action of a specific frequency of ultrasound, causing the cell membrane to vibrate, and the algae will decay and die by themselves, floating first and then sinking. At the same time, the high temperature and pressure produced by cavitation and a large number of free radicals can destroy the active enzymes and active substances in the algae cells, thereby affecting the physiological and biochemical activities of the cells. In addition, the chemical effects induced by ultrasound can also decompose algal cell secretions and metabolites such as algal toxins.
Principle of ultrasonic algae removal and algae suppression:
Ultrasonic has the function of degrading organic pollutants and removing algae. Its main mechanism is: water produces a "cavitation effect" under the action of ultrasonic radiation, and the water undergoes alternating oscillation, expansion and compression under the "cavitation effect" A series of kinetic cyclic processes such as collapse and collapse produce instantaneous, microscopic high temperature (>5000K) and high pressure (>5×107 Pa), forming hot spots (Hotopot). After a few microseconds, the hot spot cools instantaneously, accompanied by strong shock waves and micro-jets reaching 100m/s, which creates an extreme physical environment for organic matter and algae. The O-H bond of the water is broken to generate hydrogen peroxide, thereby opening up the chemical reaction channel, increasing the chemical reaction speed, and degrading the pollutants in the water under the action of high temperature, high pressure and hydroxyl radicals. Ultrasound impulses the water body and resonates the algae. The water emits pulsed sound waves of specific frequency into the water through the specially designed ultrasonic transducer submerged in the water body. Water is a good conductor of sound waves. This high-frequency wave spreads in water with little attenuation and can be worn far away. For example, the effective emission radius of a 220V\\80W ultrasonic device is 100-180m, and the effective emission angle is 180 degrees. The algae cells resonate under the action of a specific frequency of ultrasound, causing the cell membrane to vibrate, and the algae will decay and die by themselves, floating first and then sinking. At the same time, ultrasonic technology can also treat a variety of bacteria, viruses and all fungi. Many hydroxyl free radicals produced by ultrasound can degrade the algae toxins secreted by algae, will not cause secondary pollution, and are non-toxic to other aquatic organisms and humans.
