Reduce Algae and Improve the Water Quality

The algae control devices from LG Sonic emit specific ultrasonic parameters to control algae, resulting in an improved water quality.

Treated wastewater usually contains high levels of nutrients that can cause algal blooms on the water surface of storage ponds. An excess of algae can increase levels of pH, BOD and TSS, making reuse or discharge of the water difficult. The treatment of algae in waste water lagoons is important to improve the water quality before discharge in order to comply to the waste water quality standards.

The MPC-Grid controls and monitors the algae to have higher quality water that is safe to release back in the environment.  The MPC-Grid has a monitoring system which provides real-time the water quality data in the lagoon.

Benefits of algae control in wastewater

Ultrasonic Algae Control Benefits

Effective treatment to control algae

The products are developed in collaboration with several renowned universities and research institutes. The LG Sonic system eliminates up to 90% of the current algae and prevents the growth of new algae.

Ultrasonic Algae Control Benefits

Compliance with wastewater quality standards 

Permits identify monthly averages and maximum levels of BOD, Suspended Solids in the treatment effluent.

Ultrasonic Algae Control Benefits

No impact on beneficial bacteria 

LG Sonic can be used to treat wastewater lagoons to reduce the formation of algae in the lagoons without harming bacteria in charge of nutrient reduction.

Ultrasonic Algae Control Benefits

Lower Biochemical Oxygen Demand (BOD) levels

BOD is an indicator of the biological pollution of water. An excess of algae can increase levels of pH, BOD and TSS, making reuse or discharge of the water difficult.

Ultrasonic Algae Control Benefits

Lowering the amount of Total Suspended Solids (TSS)

High levels of total suspended solids will increase turbidity and decrease dissolved oxygen (DO) levels. This can negatively affect the operation process.

Ultrasonic Algae Control Benefits

Improve water quality before discharge

By lowering BOD and TSS levels, the wastewater discharges do not adversely affect aquatic recreation and/or wildlife.

Control Algae in Wastewater Lagoons with the MPC-Grid

The MPC-Grid is a floating platform that combines real-time water quality monitoring and ultrasonic sound waves to control algae effectively.

    • Eliminate up to 70-90% of the algae
    • Improve the water quality
    • Reduce pH, TSS and BOD levels

Easy Installation and low Maintenance

Can be deployed quickly and easily without the need for a crane. The system is easily accessible for maintenance while deployed.

The MPC-Grid is a modular unit that is easy to assemble and install. The system is powered from the mains (AC, DC optional). Both the ultrasonic transmitters and sensors are equipped with an automatic cleansing system. The system can be remotely managed and monitored.
