Stop algae problems

Prevent clogged filters & pipes

Down-time and maintenance costs increase operating expenses and manpower requirements.

No service interruptions

Toxic algae blooms can shutdown an entire drinking water system causing water supply shortages.

Reduce foul taste & odor

Algae release chemical compounds (geosmin, MIB) that cause taste-and-odor events.

Prevent harsh EPA penalties

Chemical treatments don’t always comply with governmental guidelines, causing warnings and penalties.

Ultrasound treatment
for lakes & reservoirs

Effective

Reduces algae up to 95%. Plus TSS, pH, BOD. Prevents new blooms. No die-off toxins.

Low-cost

Cheaper than chemicals. Less manpower. Solar-powered. Low maintenance.

Eco-friendly

Chemical-free, sustainable process exceeds EPA standards. Safe for fish, plants, and people.

How ultrasound prevents
algae growth

1

No treatment

Algae move to the water surface for photosynthesis.
2

With treatment

Ultrasonic wave blocks algae's access to sunlight & nutrients.
3

Shortly after treatment

Algae sink to the bottom and die off without releasing toxins.

Algae treatment Buoy

Treatment

Low power ultrasound treats algae with a range of up to 800m/2600ft per buoy.

Monitoring

Real-time water quality monitoring is used to predict and prevent new blooms.

Maintenance

Easily accessible from a boat. Check-up only needed once every two months.

Support

Our customer support team operates the buoy remotely from The Netherlands.

American Water
Seven years ago, American Water was the first customer to believe in LG Sonic’s technology. We’re proud of our ongoing, strong partnership.
World Waternet
Algae were degrading the water quality in a water source for 1.3 million citizens. The company achieved 50% algae reduction within 2 months.
EPM
With the help of MPC-Buoy technology, EPM could control algal blooms even in extreme environmental conditions caused by “El Niño’’ in 2015-2016.
NIPSCO
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
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
Vallecitos Water District significantly improved TSS, pH, and DO levels. Vallecitos can now provide even higher quality water to their customers.
Sellafield
To improve water visibility in Sellafield's storage ponds, 4 LG Sonic systems were installed. These systems have 12 ultrasonic programs that control algae.
