Working Principle:

Cyanobacteria and some other algae cells contain tiny gas vesicles（gas vesicles）It is used to adjust its own buoyancy to move up and down in the water column, approaching the water surface to obtain light energy.MPC-BuoyThe ultrasonic transmitter applies low-power sound waves to the surface of the water, and the generated sound pressure field can cause resonance and even collapse of these airbags. After the airbag fails, algal cells lose their ability to float and remain in the water layer with insufficient light, unable to carry out effective photosynthesis. They gradually sink to the bottom of the water and are naturally degraded by bacteria and other decomposers. This process does not directly damage the algal cell wall, so it usually does not trigger concentrated release of algal toxins.

To prevent algae from developing adaptability under sustained single frequency effects,MPC-BuoyAdopting“Chameleon Technology™” (Chameleon technology), based on real-time data feedback from water quality sensors, dynamically changes parameters such as waveform, frequency, pulse interval, and amplitude of ultrasonic waves to maintain suppression effect over a longer time scale.

5、 Advantages and Characteristics

1. Reducing the risk of toxin release through a physical inhibition pathway based on algal gas sacs

Unlike the method of directly killing algae cells through cavitation effect or chemical agents, this technology acts on the airbag structure inside algae cells, causing them to settle without rupture, and the decomposition process is relatively smooth. The concentration of algal toxins in water does not show a sharp increase. Multiple institutions have observed in third-party assessments that this method has minimal impact on fish, aquatic plants, and other aquatic organisms.

2. Ultrasound parameters can be dynamically adjusted to delay algae adaptation

Multiple types of algae may develop tolerance when continuously exposed to single frequency ultrasound waves.MPC-BuoyThe ultrasound output parameters are not fixed and unchanging, but are automatically adjusted by combining online water quality data with backend algorithms. When there is a sudden change in water quality indicators or an abnormal increase in chlorophyll, the platform can autonomously update the ultrasound program to cope with changes in algal population structure and environmental conditions.

3. Multi parameter high-frequency online monitoring and algal bloom trend recognition

Floats are used for each10Collect data on chlorophyll alpha, phycocyanin, turbidity, dissolved oxygen, etc. at a frequency of once per minute, and upload it continuously toMPC-ViewOnline platform. The system backend integrates monitoring data from over ten years of different water bodies, seasons, and algae species around the world. Through algorithm models, it determines the possibility of algal blooms and issues early warning notifications to users.

4. Low maintenance frequency, maintenance can be completed on water

The main maintenance work is carried out approximately every six months, and personnel do not need to lift the buoy back to shore during maintenance. They can perform routine operations such as sensor cleaning, transmitter wiping, and battery status checks on board the ship. The ultrasonic emission surface is equipped with an automatic cleaning brush, which rotates and scrapes off the attached biofilm at regular intervals, helping to maintain the efficiency of ultrasonic transmission. In the absence of cleaning, biological attachment can cause ultrasound output to decay more than in a short period of time50%.

5. Wide adaptability to climate, no need for seasonal recycling

The buoy can operate continuously in high temperature and drought, high altitude and strong ultraviolet radiation, or low temperature water areas in winter. Electronic components and battery compartments are equipped with corresponding protection, automatically reducing power consumption and maintaining core functions when there is insufficient sunlight. Therefore, in most geographical areas, it is not necessary to remove the buoy from the water surface in winter, which reduces the human intervention in the operation process.

6、 Main applications

According to existing public cases,LG SonicThe ultrasonic algae control device has been deployed in the following five types of water bodies:

1. Drinking water source reservoir

In lakes and reservoirs used for drinking water supply, algal blooms not only increase the treatment load of water plants, but also cause odor problems. By deployingMPC-BuoyIt can suppress algae density for a long time, reduce permanganate index, and decrease the input of disinfection byproduct precursors. dominican republicValdesiaWithin one year after the reservoir was put into use, the level of chlorophyll a decreased87%.

2. Industrial cooling water tank

Industrial circulating cooling water systems such as power plants and petrochemical plants are often plagued by excessive growth of algae, resulting in scaling of heat exchangers and pipeline blockages.MPC-BuoyandIndustrial LineBy adjusting the ultrasonic parameters to suppress algae in the cooling water tank and cooling tower collection tray, support is provided for stable heat transfer efficiency.

3. Hydroelectric power reservoir

Algae blooms in the reservoir area in front of the dam may lead to blockage of the trash rack and thickening of the attached biological layer of hydraulic structures. A water surface in Florida, USA1700Acres of hydroelectric reservoirs are being deployedMPC-BuoyAfterwards, the biomass of algae decreased by about87%Reduced the frequency of related cleaning work.

4. Municipal sewage and landscape water bodies

Stable ponds and facultative ponds in sewage treatment plants, as well as urban landscape lakes and park waters, often experience outbreaks of blue-green algae blooms due to high nitrogen and phosphorus loads. The buoy system plays an auxiliary role in reducing suspended solids and biochemical oxygen demand in the effluent, and also helps to reduce the occurrence of odors and algal slurry accumulation in landscape water bodies.

5. Agricultural irrigation reservoir

The filamentous algae and single celled algae that grow in irrigation channels and reservoirs are prone to clogging the filters and drippers of drip irrigation systems. Ultrasonic algae control can inhibit the proliferation of most planktonic algae and some attached algae, thereby ensuring the hydraulic smoothness of the irrigation system.
