EU-research 'clears' the way for high quality lakes and reservoirs

The growth of blue-green algae in our lakes, large ponds, water reservoirs and public waters constitutes a problem for our environment and for our health. These types of algae often result in a deterioration of the water quality and emit a distinctly unpleasant odour. The algae consume a lot of oxygen in the water, leaving little for other animals like fish. They also produce toxins which can cause skin irritations and are suspected to be involved in the occurrence of liver cancer.

Traditional algae controlling methods (e.g. aeration, chemical or biological additives, and others) are not sufficiently effective when it comes to larger waters. They may also be associated with high labour costs and potentially negative environmental impacts, especially when chemicals are used. In order to address these problems, the EU-funded CLEARWATERPMPC project has successfully developed and commercialised an environmentally-friendly technology. Known as the MPC-Buoy, the CLEARWATER solution uses ultrasound technology to prevent the growth of blue-green algae.
