87% algae reduction to improve drinking water
The country’s most important water source After years of struggle with algal blooms, The Santo Domingo Water and Sewage Corporation (CAASD) installed multiple MPC-Buoy systems to cover the 7km²/2.7mi² Valdesia reservoir. The first results were visible after two weeks, and the project exceeded the targets for the first year with a 87% reduction in algae levels. The Valdesia reservoir is the main drinking water supply for the population of the…
Improved water quality with MPC-Buoy
Improving water quality In sunny California, MPC-Buoy technology is controlling algae in reclaimed water since 2018. Vallecitos Water District provides 5.25 million gallons of recycled water for irrigation every day. TSS levels need to be low to fulfil the demands of modern irrigation systems. Algae increases TSS and clog the filters that are in place to remove TSS prior to the distribution to the irrigation systems. This allows for…
Lakes remain open during algae season
Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. To ensure that the concentration of cyanobacteria remained at an acceptable level at a popular public open space…

The main objective of the project was to reduce algae problems, especially during summer months, with secondary objectives to reduce chemicals costs, decrease backwashes,…
5 years and 5 successful projects with EPM
Control of (cyanobacterial) algal blooms In 2015, LG Sonic began the first project with EPM, installing eight MPC-Buoy systems in the La Fe reservoir in Colombia. The water body is the main drinking water source of the city of Medellin. Since the installation of the systems, algal blooms have been controlled effectively, even in the extreme environmental conditions of ‘’El Nino’’ in 2015-2016. The interactive algae control systems allow to…
Six years of partnership with South West Water
Sustainable partnership Since 2014 South West Water, formerly Bournemouth Water, is using LG Sonic MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. High algae concentrations in reservoirs used for drinking water purposes causes increased chemical dosage and blockages of filters and pipes within the water treatment plant. South West Water holds health and wellbeing of people and the environment in their core values. Environmental health is critical to…
Algae treatment in the largest dam in Lebanon
Controlling algal blooms After dealing with algal blooms for years, World Waternet and the Litani River Authority installed 11 LG Sonic systems to cover the northern part of the 12km2 Lake Qaraoun. Two months after the start of the ultrasonic algae control project, the algae have been reduced by 50%, with higher results achieved in later months. Lake Qaraoun is the major drinking water source for 1.3 million citizens…
88% reduction in total suspended solids
Data-driven technology The Quiport International Airport, Mariscal Sucre, has a reservoir built to control the runoff generated by rainwater, and the capacity to retain a storm with a return frequency of 100 years. Previously, the reservoir had a problem with excessive algae growth, increasing PH levels (<7) as well as organic matter levels. This made it attractive for the wildlife found in the ecosystem adjacent to the airport, which represented…
82% less chlorophyll-a in the City of Minneapolis
Clean drinking water with ultrasound technology In City of Minneapolis, Minnesota, US – The Mississippi River is the only source of drinking water for half a million residents. Each year, the Water Treatment & Distribution Service (WTDS) pumps approximately 21 billion gallons of water from the river. The extracted water goes through multiple treatment processes before it is safe for human consumption. Therefore, ensuring the highest level of water quality…
90% less algae in potable water of Superior, Colorado
Improving drinking water quality Town of Superior receives most of its raw water from snowmelt in the Upper Colorado River. The water travels through a sequence of canals and pipes before making its way to the storage reservoir at the water treatment plant south of Original Town. The drinking water supply is stored before being treated for consumption at the Terminal reservoir. This reservoir can hold approximately 130 million gallons…
Reduced blue-green algae counts
Improve water visibility After the installation of multiple LG Sonic Industrial Wet Systems in a nuclear power plant of Sellafield (UK) the water visibility in the storage ponds improved significantly.

The unit was connected to a local power source. Ultrasonic treatment uses high frequency sound waves to control algae…
Dramatic reduction in algae concentration
Malodour caused by blue-green algae Lake Taman Aman is contaminated by algae and the inflow of liquid waste from the surrounding buildings. Thanks to the blooming of blue-green algae, the lake suffered particularly from malodour. In September 2012, four LG Sonic e-line’s where installed in the lake to deal with the stench. Lake Taman Aman is contaminated by algae and the inflow of liquid waste from the surrounding buildings. Thanks…
90% reduction in filamentous algae
Control filamentous algae and diatoms In July 2011, the golf course pond at the Lethbridge country club was treated with LG Sonic Technology. The water surface was covered by mats of filamentous algae, while the rocks within the pond were covered by Didymosphenia geminata, also known as Dydimo. This invasive (diatom) algae is an emerging problem in North America. The Lethbridge country club golf course pond with the following dimensions:…
Improved water clarity in an aesthetic pond
Improve water clarity Every year as soon as the summer weather arrived so did all the algae growth in the pond. Even after trying different methods to get rid of the algae, the problem returned. The algae ruined the view of the pond and made the water (extremely) green. In their search for a long-term solution, the answer to their algae problems always seemed to be to physically remove the…
