LG Sonic algae control proven safe for Zooplankton

A recent study commissioned by the Dutch water board and conducted by Ecofide, a research agency, found that there are no negative effects of ultrasonic sound waves on Zooplankton from the MPC-Buoy. The research was conducted as part of a two year pilot project of the Zoetermeer Municipality, Hoogheemraadschap van Rijnland and LG Sonic to study the applicability of the MPC-Buoy systems for a recreational lake in Zoetermeer, The Netherlands.


Algae growth main target

Known for implementing solutions for environmental issues such as algal blooms with negatively affecting other organisms in the ecosystem, LG Sonic’s technologies are chemical-free, environmentally friendly, and only impact algae, the target organism.

This is important as in lakes, algal blooms may affect the balance between bacteria, plants, insects, and other organisms in a negative way, resulting in severe consequences over time. When proposing a solution also negatively affects other organisms in the water body, the natural balance cannot be restored, and the lake will be left dependent on human intervention to control the algae.

The effects of LG Sonic’s ultrasonic algae control products were also tested by various universities and research agencies, and proven to be safe for fish, plants, and insects. In a two year pilot project in the Netherlands, a study regarding the effects of the MPC-Buoy systems on the survival and reproduction of zooplankton was also conducted, and found no negative effects.


The MPC-Buoy

A floating, solar-powered system that combines real-time water quality monitoring and specific ultrasonic sound waves to control algae in large water surfaces effectively, a unit was recently installed in a drinking water reservoir in Emmitsburg, Maryland, United States (U.S.) and succeeded in both controlling algae and reducing costs as well as water lost.

LG Sonic runs algae control projects with top-level water utilities such as EPM and American Water to keep their drinking water reservoirs free of algae.
