Ultrasound waves for specific algal groups

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, and clogged filters. The town has been facing high algae growth during summer, resulting in double water consumption, which was needed for backwashing algae and dirt out of the plant’s system.

Since the installation the lake is clearer, NTU's are lower and water usage decreased.

A MPC-Buoy system was installed to control the long-term algae problem in Rainbow Lake. The MPC-Buoy combines real-time water quality monitoring and ultrasonic sound waves to provide a complete and environmentally friendly algae solution in large water surfaces.

Saved money and water

Since the installation of the ultrasound units, the algae control system has proven itself. Costs are reduced significantly, overall chemical costs decreased by 27% in 2017, the water quality improved, overtime at the water plant was reduced by 31 percent, and backwash water usage decreased over the year.

“The device performed excellently when dealing with blue-green algae“.

Cathy Willets, Emmitsburg Town Manager

 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…
