How LG Sonic technology works

Without treatment

Algae move to the water surface for photosynthesis to grow, and to the bottom of the water column for nutrients.

LG Sonic treatment

Ultrasonic wave blocks algae's access to sunlight & nutrients. Algae sink to the bottom and die off without releasing toxins.

Read full case study

Seven years ago, American Water was the first customer to believe in LG Sonic’s technology. We’re proud of our ongoing, strong partnership.

Algae were degrading the water quality in a water source for 1.3 million citizens. The company achieved 50% algae reduction within 2 months.

With the help of MPC-Buoy technology, EPM could control algal blooms even in extreme environmental conditions caused by “El Niño’’ in 2015-2016.

Since using the MPC-Buoy, NIPSCO’s TSS levels never exceeded monthly average for compliance. This year, they won the Power Mag Water Award.

CAASD’s Valdesia reservoir has a surface of 7km²/1700 acres. After years of algae bloom contamination, the utility achieved 87% chlorophyll a reduction.

Vallecitos Water District significantly improved TSS, pH, and DO levels. Vallecitos can now provide even higher quality water to their customers.

To improve water visibility in Sellafield's storage ponds, 4 LG Sonic systems were installed. These systems have 12 ultrasonic programs that control algae.
