Control Invasive Mussel Biofouling to Improve Plant Availability and Reduce Maintenance

Marrone, Webcast Experts, Boifouling



Hydroelectric, fossil, and nuclear power plants that rely on freshwater, are particularly vulnerable to biofouling caused by invasive zebra and quagga mussels. Infestations by these mussel species have grown considerably since being unintentionally introduced into the U.S. Great Lakes in the 1980s. Rapid proliferation occurs as these mussels attach to hard surfaces, structures, and even one another to form dense colonies which can clog pipes, filters, and screens, in addition to damaging mechanical equipment. Plants incur increased maintenance costs, unexpected outages, and reductions in power generation. In the 10-year period from 2000-2010, the U.S. Fish and Wildlife Service (USFWS) estimated the economic impact associated with these invasive species at $5 billion.

As the geographical area of infestation impact in the U.S. increases, the role of control methods is paramount. Commercial and public entities facing zebra and quagga mussel infestations have applied a variety of methods when seeking to control mussel populations, including aqueous controls (notably chlorine addition), antifouling coatings, physical removal and mechanical controls. Each of these methods has significant drawbacks associated with toxicity, safe handling, excessive labor, and corrosion.

Marrone Bio Innovations has developed Zequanox® molluscicide, an effective biological solution which utilizes killed cells of a naturally occurring soil microbe. Zequanox offers several advantages over chlorine and other control methods, including safety, flexibility and ease of use. First and foremost, Zequanox poses no risk to workers, non-target species and the environment when used as directed.

In this informative webinar, Seth Donrovich, Zequanox Product Manager for Marrone Bio Innovations, will discuss Zequanox and how it is a solution for the invasive mussel problem. Specific topics to be addressed include:

  • The proliferation of Invasive mussels - a multi-billion dollar problem

  • Brief comparison of Zequanox to alternative control methods

  • Customizing the control program – full control or maintenance

  • Proven success – case histories in the US and Canada

Attendees can ask additional questions which will be covered during the Q&A session at the end of the webinar.
