Nontoxic foul-release coatings
Technical Report
·
OSTI ID:5491617
The Electric Power Research Institute (EPRI) under project RP-1689-9 evaluated 30 non-toxic coatings for biofouling control on steel and concrete surfaces of cooling water intakes and piping. Seven coatings were evaluated at seven sites for 2 year. The remaining 23 coatings were exposed for a variety of time lengths at the Battelle Marine Laboratory at Daytona Beach, Florida. Accelerated corrosion tests and inspection of the test panels to determine coating life were also conducted. Results of several utility conducted tests were also solicited. Silicone-based coatings performed the best with predicted lives of 2 to 4 year. Although the non-toxic coatings can be fouled by biogrowth, the rate of fouling is less and the coating can be easily cleaned. A cost-benefit methodology is presented to aid utilities to assess the potential use of non-toxic foul-release coatings at power plant cooling systems. 12 refs., 16 figs., 35 tabs.
