The Next Level Solution for Algae Control in Wastewater
Last month LG Sonic installed its first algae control project in Dubai. Three MPC-Buoy units have been installed in a wastewater reservoir. The units will monitor the water quality in real-time and use specific ultrasonic sound waves adjusted to the algal type present to effectively control algal growth.

Algae in wastewater
Treated wastewater usually contains high levels of nutrients that can cause algal blooms on the water surface of a wastewater lagoon. An excess of algae can increase pH, BOD and TSS levels, making reuse or discharge of the water difficult. The treatment of algae in wastewater lagoons to improve water quality before discharge is vital in order to comply to the wastewater quality standards. Using MPC-Buoy, wastewater treatment plants can monitor wastewater quality in real-time and control algal growth.

Wastewater discharge
To monitor, predict and control algae in wastewater lagoons, LG Sonic offers an MPC-Buoy solution without solar panels, called the MPC-Grid. The system is powered from the mains (AC, DC optional) to treat smaller water bodies, such as wastewater lagoons. Controlling algae with MPC-Grids lowers the amount of Total Suspended Solids (TSS). High levels of TSS increases turbidity and decreases dissolved oxygen (DO) levels. This can negatively affect the operation process. By lowering BOD and TSS levels, wastewater discharge does not adversely affect aquatic recreation and/or wildlife.

MPC-Grid wastewater solution
The MPC-Grid is a floating platform that provides continuous online water quality monitoring and uses ultrasound technology to control algae. At LG Sonic, we use scientifically proven ultrasonic frequencies to control many types of algae, such as cyanobacteria. The ultrasonic sound waves create an ultrasonic pressure in the top layer of the water and prevent the algae from rising to the surface and absorbing light for photosynthesis. Because of this, algae are no longer capable of growing further and will sink to the bottom of the reservoir and are degraded by the bacteria presented. In the case of wastewater, the solution is to anchor one or multiple MPC-Grid systems that makes use of interactive ultrasonic programs which are necessary to control algae effectively in the long-term.
