Control algal blooms with MPC-Buoy

A complete solution for algal blooms in lakes and reservoirs by using LG Sonic ultrasound technology.

What is MPC-Buoy?

Treatment range

MPC-Buoy is low maintenance, easy to use, scalable solution to control algal blooms in large lakes and reservoirs. It uses LG Sonic’s interactive ultrasound technology with integrated water quality monitoring.

The system is anchored in the lake or reservoir and has a treatment range of 500 meter / 1600 feet in diameter. Multiple systems can be installed to treat larger areas.

Five reasons our customers choose MPC-Buoy

  • Reduce algal blooms up to 70-90%
  • Lower TSS, pH, BOD and chemical usage
  • Remotely operated by LG Sonic
  • Developed with universities
  • Proven safe for fish and plants

How does the system work?

MPC-technology

MPC-Buoy uses LG Sonic’s patented LG Sonic ultrasound technology. Completely autonomous MPC-Buoy monitors the water quality in real-time and uses this data to predict and control algal blooms.

1. Monitor

Real-time algae and water quality data is collected

2. Predict

This data is used to predict algal trends

3. Control

The ultrasound is adjusted to the specific conditions

1. Monitor algae growth

MPC-Buoy provides a complete overview of the water quality by collecting the following parameters every 10 minutes:

  • Chlorophyll α (green algae),
  • Phycocyanin (blue-green algae),
  • pH,
  • Turbidity,
  • Dissolved Oxygen,
  • Temperature.

2. Predict algal trends

The collected data is delivered in real-time via 3G/4G to a web-based software. By making use of Artificial Intelligence, MPC-Buoy modifies the ultrasonic program to the specific water conditions and predicts an algal bloom up to 3-10 days ahead. Our customers have access to their water quality data via the MPC-View water quality software.

3. Control algal blooms effectively

The MPC algorithm activates the optimal ultrasonic treatment frequencies according to the water conditions and type of algae present. The ultrasound creates a sound layer that prevents the algae from accessing sunlight and nutrients. By fixing the algae in the water column, it reduces existing algae and prevents the growth of new algae.

System features

System features

Monitor, predict and control algal blooms in large water surfaces without chemicals.

Effective algae control

Eliminates 70-90% of existing algae and prevents the growth of new algae. MPC-Buoy allows for a reduction of pH, TSS, BOD, and chemical consumption.

Safe for the environment

The ultrasound used by LG Sonic proven is safe for fish, plants, zooplankton, and insects. Our devices use of low power ulltrasound.

No release of toxins

Unlike when applying chemicals, the cell wall of the algae remains intact. Preventing the release of toxins from the algae into the water.

Developed for large surfaces

Each MPC-Buoy device can control algae in areas up to 500m/1600ft in diameter. Multiple buoys can be installed for large water surfaces.

Low operational costs

The system operates autonomously on solar energy and has an integrated Aquawiper to prevent frequent site visits.

Suitable for any water depth

MPC-Buoy uses LG Sonic ultrasound technology and is applicable to any water depth with a mnimum of 1,5 meter.

Installation and maintenance

Installation and maintenance

MPC-Buoy can be quickly deployed. The system is anchored in the reservoir. The water quality sensors and ultrasonic transmitters on MPC-Buoy are equipped with a Aquawiper which automatically cleans the sensors after each reading, keeping the maintenance to a minimum and the readings accurate.

The technical status of the system can also be monitored through the MPC-View software, minimizing visits to the MPC-Buoy itself.

NIPSCO chooses a greener path to comply with NPDES

Complying with NPDES regulations In the search of an eco-friendly and effective solution to comply with NPDES discharge regulations, NIPSCO installed 5 MPC-Buoy systems at R. M. Schahfer Generating Station in Indiana, USA. High TSS and pH are mainly caused by algal blooms which are now treated with the ultrasound technology of LG Sonic. NIPSCO uses a large reservoir for settling out suspended solids prior to discharging the water back…

Improved water quality with MPC-Buoy

Improving water quality In sunny California, MPC-Buoy technology is controlling algae in reclaimed water since 2018. Vallecitos Water District provides 5.25 million gallons recycled water for irrigation every day. TSS levels need to be low to fulfil the demands of modern irrigation systems. Algae increases TSS and clogs the filters that are in place to remove TSS prior to the distribution to the irrigation systems. This allows for less cleaning…

Sustainable partnership Since 2014 South West Water, formerly Bournemouth Water, is using LG Sonic MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. High algae concentrations in reservoirs used for drinking water purposes causes increased chemical dosage and blockages of filters and pipes within the water treatment plant. South West Water holds health and wellbeing of people and the environment in their core values. Environmental health is critical to…

FAQ

Below you find a list of frequently asked questions and answers for a few common topics. If you cannot find the answer to your question, please feel free to reach out.

  • What is the size of the MPC-Buoy?

    The MPC-Buoy has the following dimensions 254cm x 218,8cm x 86cm and weights 160kg. One MPC-Buoy system can treat areas up to 500 meter (1600ft) in diameter.

  • How does the MPC-Buoy communicate?

    MPC-Buoy is linked with the MPC-View software. This provides the opportunity to visually gain real-time data about the water quality and the status of the LG Sonic transmitters.

    The software will provide the monitored and collected information via charts, tables, and sheets on a personal web page. In this way, a complete and clear overview is given.

    MPC-Buoy communicates through a GSM/GPRS telemetry quad band in which 850/900/1800 or 1900 MHz is possible. Through the GSM control, monitoring and changing the ultrasound program remotely is possible.

    Furthermore, it is possible to set alerts for changing water conditions. The communication between the several MPC-Buoys is conducted through a radio (UHF/VHF0).

  • Can solar panels provide power all year long?

    Yes, the buoy is equipped with 3 solar panels of 195 Wp, and the batteries provide 3 to 5 days’ autonomy. This makes MPC-Buoy perfectly capable to receive sufficient power to operate all year long in every country.

  • Can I also use MPC-Buoy for the smaller ponds?

    MPC-Buoy: This version has 3 solar panels, a treatment range of 500 meters, and a buoy to install it in the middle of the lake.

    MPC-Grid: This is a smaller version of the buoy because it does not include the solar panels and batteries. The power is supplied via a cable to the float. This unit can have a variable amount of transmitters and strengths to fit any type of pond.

  • Once installed in the water, will the MPC-Buoy move in the water?

    When the MPC-Buoy is implemented in the water, it can move slightly. However, after a few days it will stay at one point.

    The system is moored to strengthen the balance and prevent drifting. Depending on the water surface level and flow, it is possible to choose between 1-point mooring, 2-point mooring, or 3-point mooring.

  • What is the cost-benefit comparison with other algae control methods?

    Our systems have a lifetime of around 10 years and no electricity costs because they are solar powered. Therefore, we see that in relation to chemicals, the return on investment can already be within 1.8 years.

    Compared to other technologies that require energy, such as aeration, the Return On Investment of MPC-Buoy is much shorter.
