Field Scale-up testing of Foul Release Coatings

Project ID: 5270
Principal Investigator: David Tordonato
Research Topic: Repair and Maintenance
Priority Area Assignments: 2013 (Zebra and Quagga Mussels), 2014 (Zebra and Quagga Mussels), 2015 (Zebra and Quagga Mussels)
Funded Fiscal Years: 2013 and 2014
Keywords: foul release coatings, scale up, zebra, quagga

Research Question

Is it possible to use foul release coatings to prevent the attachment of zebra and quagga mussels on Reclamation Infrastructure? Will existing foul release coatings provide a service life which is deemed acceptable to facility owners?

Need and Benefit

Impacts on Reclamation facilities due to zebra and quagga mussel infestations are currently being experienced at Reclamation facilities on the lower Colorado river. Overall impacts at Reclmation are expected to increase as mussels continue to reproduce and spread to other reserviors. While efforts to prevent the spread of mussels are underway at Reclamation as well as other federal, state, and local agencies, facility owners will need options keep hydraulic equipment functioning in the event of a mussel infestation. Foul release coatings offer one solution. While field studies have been underway for 4 years, management is unlikely to embrace new coatings technology unless it has been successfully demonstrated on actual equipment i.e. a scale up test. A successful test would give operations and maintenance personnel confidence that foul release products can stand up to the expected service environment.

The grate is expected to be installed in FY13. Progress reports will be filed as required by S&T.

Activities in FY14 and FY15 will each result in an inspection report / coating status update to be distributed as needed. FY15's report will serve as the final report for the project unless funding is extended beyond FY15.
