MPC-Buoy in operation since 2017

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 a risk to the aerodrome’s operational security (a danger of impact between the wildlife and the aircrafts), for which it was necessary the use of chemical products (algaecides), to maintain partial and temporary control.

MPC-Buoy installed in the Quito airport reservoir.

In 2015, a study of options for algae control considered the MPC-Buoy system as the best choice because it provided a long-term solution and a low environmental impact since it does not generate hazardous waste or health risks for operators. Since the installation of the LG Sonic ultrasound units in early 2017, the use of chemicals has been significantly reduced, which it also reduced the manpower and hours of work required to control the algae.

The use of this system also allowed to keep a real-time record of the water quality parameters, observing a reduction of 88.36% in the total solids and therefore also the turbidity of the water body, additionally a significant reduction in algae on the surface in sample analysis.

“Regular monitoring of the rainwater reservoir shows a positive impact of the MPC-Buoy system on algae control and improvement in water quality“.

Reduced blue-green algae counts in New Zealand

Reducing blue-green algae counts In the Lower Nihotupu Dam in Auckland, New Zealand, five solar-powered algae control systems are controlling blue-green algae blooms. The project started in December 2016 and it proved to be a great success. The algae counts have significantly decreased over the summer, as compared to the previous year. The water utility’s main objective was to reduce blue-green algae counts in a dam used as a water…

Saving money and water with MPC-Buoy

Control algae problems A floating solar powered algae control system was installed in Emmitsburg (US) to control algae in a reservoir that provides drinking water to approximately 3,000 people. The MPC-Buoy system, installed in April 2017, succeeds in controlling algae, reducing chemical costs and water usage. The main objective of the project was to reduce algae problems, especially during summer months, with secondary objectives to reduce chemicals costs, decrease backwashes,…

Control and monitor toxic algal blooms The ClearWaterPMPC project was initiated by LG Sound and funded by “Research for SMEs” within the EU 7th Framework Programme. The goal of the ClearWaterPMPC (Predicting, Monitoring,Preventing, and Controlling) project was to develop an environmentally friendly technology to prevent growth of blue-green algae in large water reservoirs. In contrast to currently available ultrasound based algae control systems, the technology developed within the scope of…
