Hydrolox Fish Friendly Polymer Screens - Designed for Compliance with 316(b)

This  presentation willdocument the results of numerous independent laboratory and in-field tests, and highlight the value that Hydrolox screens have consistently provided for many companies and organizations, all while providing a platform for 316(b) compliance.  Hydrolox determinedly researched and tested existing steel mesh screens in order to understand how cooling water intakes might be made more effective. It then challenged its engineers and designers to come up with a design that could both protect aquatic life and radically reduce operational and maintenance costs. The result is a strong, modular screen with superior resistance to abrasion, bio-fouling and impact that also saves a high percentage of aquatic life. To validate the ability of the polymer screening technology to protect aquatic life, several studies on impingement and or entrainment have been conducted.  The presentation will cover impingement results from Alden Laboratory and from an independent environmental testing company at a NY power station, the results of an entrainment study by Alden Laboratory under the sponsorship of EPRI, and the results from a 2 year study on impingement and entrainment on the River Thames in England. These studies demonstrate that Hydrolox screens provide a high survivability rate across a diverse range of species in a variety of challenging environments.
