A Continuous-Flow Facility for Zebra Mussel Research and Control.

Abstract
The extensive biofouling by zebra mussels (Dreissena polymorpha and D. bugensis) presented new demands on industrial water users in North America. Foremost among these was the need to develop and test the effectiveness of techniques that would prevent and control mussel fouling under realistic conditions. Unfortunately, testing facilities to undertake such research and development, using raw lakewater, natural populations of larvae and translocating mussels, were not available. We, therefore, report on a research facility, which was designed and remains in use at Ontario Hydro's Nanticoke Thermal Generating Station on Lake Erie to evaluate control measures for zebra mussels. The facility consists of a continuous-flow system, which supplies raw lakewater to 20 flow cells (12.7 cm diameter x 91 cm in length). The velocity through each flow cell can be controlled to relate treatments options to the biology of mussels, and to assist in the development of monitoring programs. This facility has provided valuable insight into zebra mussel biology and mitigation techniques including the optimization of chlorine treatment. It is believed that the present design provides a better model for such development versus static or open-channel test conditions.
