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, 2014 and 2015
Keywords: foul release coatings, scale up, zebra, quagga
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.
