What is your technology?

MPC-Buoy controls algae in large water surfaces by using real-time water quality monitoring and remote sensing to analyze current algae and to predict algal blooms. The technology is based on ultrasound, which can effectively control algae by using specific frequencies, amplitudes, etc., due to algae differing in size, composition, and gas vesicle formation. An MPC-Buoy contains in-situ sensors that measure chlorophyll-a, Phycocyanin, turbidity, temperature, dissolved oxygen, pH and redox, which are sent through 3G or other data connections to an online server. This data is used to analyze the type of algae and their growth stage to effectively emit the correct ultrasonic sound waves.


What are the benefits of implementing your technology?

LG Sonic Ultrasound controls algae chemically free, without harming other organisms by preventing them from rising up to the water surface. In many cases, the system completely replaces the need to chemically treat lakes or reservoirs. Furthermore, MPC-Buoy allows the reduction of TSS, BOD, and operational costs. Each system has a treatment range of 1600 ft. (500 m) in diameter – multiple systems can be installed to cover larger water surfaces.

LG Sonic advantages:

A MPC-Buoy system has an algae treatment range of 1600 ft. (500 m) in dia.
  • Reduce algal blooms up to 90%.
  • Cost-effective compared to chemical use.
  • Environmentally friendly, no release of toxins.
  • Safe for fish, plants, zooplankton, and insects.
  • Solar-powered system to treat large water surfaces.


Has the technology been tested, demonstrated, or implemented anywhere to date?

Since 2014, LG Sonic MPC-Buoy systems have been installed in more than 25 countries worldwide. The solution is used in various applications such as drinking water reservoirs, recreational lakes, and cooling ponds. Since 2015, LG Sonic is an Official Certified Innovation Partner of American Water, the largest water and wastewater utility in the United States.


LG Sonic ultrasound technology is proven to be safe for humans, fish, and other aquatic life.

What are some of the next steps needed to advance the technology?

MPC-Buoy systems are installed in the reservoir or lake itself. In some of the countries where systems are installed, vandalism is of concern in places that are accessible to the public. LG Sonic is working on methods to protect the systems against vandalism or theft through GPRS alerts, warning lights, and solid anchoring systems. Since launching in 2014, we have continued to improve the MPC-Buoy system. In recent years, we added satellite communication to support locations outside of 3G/4G areas and developed a new sensor set for more accurate and faster readings of the water quality. Our water quality software, MPC-View which is used to access the data from the MPC-Buoy system, is in continuous development. We recently added further support to integrate our software in other software information systems. Furthermore, LG Sonic recently introduced a new solution – MPC-NanoBubble which is the only system in the world that moves autonomously through a waterbody to oxygenate a lake in its entirety by using pure oxygen nanobubbles. MPC-NanoBubble can be installed along MPC-Buoy systems to improve the water quality.


LIFT has helped us to introduce our sustainable algal bloom solutions to future clients.
