Study confirms scalewatcher can control mussel settlement
(10/1/2001) -- A study undertaken by Aquatic Sciences Inc. has demonstrated that under test conditions, the Scalewatcher Electronic System can successfully control the settlement of zebra mussels in pipelines.
A study undertaken by Aquatic Sciences Inc. (ASI) has demonstrated that under test conditions, the Scalewatcher(R) Electronic System can successfully control the settlement of zebra mussels. Pilot-scale application of the technology will determine if zebra mussel settlement in pipes and water inlets can also be successfully controlled. The research, commissioned by Scalewatcher North America Inc., was carried out over a six week period along the Welland Canal in Southern Ontario, where densities have historically exceeded 20,000/m^sup 2^. Results showed that the Scalewatcher system had reduced the amount of molluscs by up to 97 percent.

The impact of zebra mussels now extends from the Great Lakes watershed to the mouth of the Mississippi River. They affect industry and smallvolume water users by clogging pipes and intake structures. Industries in infected areas regularly treat the water with oxidants, heat or molluscides to eradicate zebra mussels from the service water system. Heightening awareness of aquatic environments and health issues has resulted in increased regulations and lower discharge limits for chemical treatment, resulting in industry now requiring alternative methods to control infestations.
The Scalewatcher system is extensively used in industry throughout the world to control fouling resulting from the build-up of scale. Industries in Japan found that the system controlled not only scaling but also crustaceans in the piping system to a heat exchanger. This observation led Scalewatcher North America Inc. to hypothesize that the Scalewatcher system may also control zebra mussels.
