How it works

Monitor water quality

The Monitoring Buoy offers a complete overview of the water quality by collecting the following parameters every 10 minutes:

Chlorophyll α (green algae)
Phycocyanin (blue-green algae)
pH
Turbidity
Dissolved Oxygen
Temperature

Extra parameters and vertical profiling available upon request

Predict algal blooms

The algorithm developed in cooperation with research institutes allows you to predict algal blooms 3-10 days in advance. Plus, you gain other valuable insights:

Seasonal alage trends
Predict algae counts
Set custom alerts
View data in charts, tables, and spreadsheets on your personal webpage

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

Anglian Water reduced up to 95% of algae counts with ultrasonic treatment. The Alton WTW supplies water to 92,214 properties in the Suffolk area, U.K.

Saeta Yield is a power generation plant in western Spain. Their raw water pond contained excessive algae, causing pipes, filters, and pumps to clog.

WTDS’ greatest concern was that algae would clog membranes in the filtration plant. LG Sonic became an integral part of the treatment process.

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

South West Water was one the first utilities in the UK to install the MPC-Buoy in their water treatment process back in 2014.

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.

A popular public open space with 2 lakes used for water skiing, fishing and sailing was contaminated with algae blooms.

American Crystal Sugar Company is the first company in the sugar beets industry to start using ultrasound technology to improve water quality.

NZ utility needed to reduce blue-green algae in a dam used for water supply. During summer, algae cause damage and increase the process costs.

Dubai Municipality selected MPC-Buoy systems to control algae blooms because it's chemical-free and offers real-time water quality monitoring.

The main objective was reducing algae during summer, as well as reducing chemicals costs, decreasing backwashes, and preventing clogged filters.

Town of Superior was named after the "superior" quality of coal found in the area. The town’s raw water supply delivers water to approximately 12,483 citizens.

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

Many lakes in Poland generally suffer from cyanobacterial blooms during summer. The algae issue was mitigated with the help of LG Sonic systems.

Salto Grande: “In open water systems, LG Sonic raises one of the best responses within the existing technologies, sustainable over time.”
