Ultrasonic Algae & Biofilm Controllers
In field applications for more than 10 years, low powered/low frequency ultrasonic units have proven to be an effective non-invasive method for controlling algae growth in lakes and reservoirs. More recently, significant developments have been achieved in applying this technology to recirculation systems such as cooling towers and irrigation systems to control biofilm.
Environmental Sustainability Through Innovation
Useable water is a basic building block for environmental sustainability. Achieving this goal is an ever increasing economic challenge as well as environmental. Protection of this natural resource is essential. Water quality around the world has been deteriorating while demand increases.
Envirotechnology
In the past, chemicals have been used to control algae and cyanobacteria in lakes and reservoirs or control of biofilm in circulation piping. In addition to being costly, heavy chemical treatments have created unintended consequences. Europe has banned the use of herbicides. In the United States, there is increase pressure to limit or ban entirely the amount of copper based herbicides. The commercial stimulus caused by the lack of herbicides for control of algae, and the growing public perception that nothing should be added to water, has lead to the development of new envirotechnologies.
In real-life environments, every water body is different and ever changing. Understanding of the various bio-mechanisms involved at the cellular level as well as within ecosystems will ultimately be the guide for using ultrasonic frequencies to control algae and biofilm in water treatment of the many different applications.
