Algal blooms and zebra mussel´s infestations are an increasingly concern, as they can have ecological, aesthetic, human health and economic impacts. The economic losses are mainly related to both the precautionary measures taken to avoid more severe impacts (monitoring and management cost) and the direct effects in human health, fishery and tourism & recreation. Current methods to control species proliferations are harmful for the aquatic life, are limited to a reduced number of species, entail important maintenance and installation costs and its efficiency depends on site-specific conditions. Thus, there is an urgent need for cost-efficient solutions to prevent and control algal blooms and zebra mussels’ invasion without damaging the ecosystem. To solve this problem, we have developed an ultrasound technology which covers for the first-time an eco-friendly prevention, control and elimination of both zebra mussel´s infestations and algal blooms at the most competitive price.
