MPC-Buoy

Monitor and control algal blooms

MPC-Buoy controls algal blooms in large lakes and reservoirs. It uses LG Sonic’s interactive ultrasound technology with integrated water quality monitoring.

  • Reduce algal blooms, TSS, pH and BOD
  • Lower chemical usage and maintenance time
  • Remotely operated by LG Sonic

How it works

Monitor

1. Monitor

The 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, and Temperature.

Predict

2. Predict

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.

Control

3. Control

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.

Treatment

Ultrasonic algae treatment

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

  • 500 meter / 50 acres treatment range
  • Low power ultrasound
  • Improve water quality safely

Installation & 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.

  • Remotely operated by LG Sonic
  • Easily accessible
  • Integrated wiper systems

Environmentally friendly

Safe and proven

The ultrasound used by LG Sonic proven is safe for fish, plants, zooplankton, and insects. Our devices use of low power ultrasound. Unlike when applying chemicals, the cell wall of the algae remains intact. Preventing the release of toxins from the algae into the water.

  • No release of toxins
  • Chemical-free
  • Safe for fish, zooplankton and water plants

MPC-View Water quality monitoring software

Overview

MPC-View is an advanced web-based water quality monitoring software. The software allows to generate a complete overview of the water quality of one or multiple water bodies.

  • Web-based software
  • User friendly

Visual insights

The software provides insights into the water quality, algae trends, and progress of the ultrasonic treatment in the lake or reservoir.

Dashboard

Users can log in to the software, where they can find a personal dashboard with an overview of the water quality and MPC-Buoy system status.

Real-time alarms

The software allows users to set up specific alarms to inform about changing parameters. Users receive an e-mail notification when the alarm goes off.

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…

Lakes remain open during algae season

Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. To ensure that the concentration of cyanobacteria remained at an acceptable level at a popular public open space…

Eliminated chemical usage in the raw water reservoir

Addressing episodic taste and odor events Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. The four buoys operated for five months in the spring/summer 2014. As an alternative to copper-based algaecides, the use of ultrasonic treatment can be used to control algae. Ultrasonic treatment uses high frequency sound waves to attack the algal cells….
