Biofouling Potential on Fine Mesh Wedge Wire Screens and a Test of Some Mechanisms for Biofouling Control

摘要

Wedge wire panels of two slot widths (1 mm and 3 mm) were immersed at the Chalk Point Steam Electric Station intake canal in the Patuxent estuary for one month periods from June 1982 to August 1983 to determine fouling rate at the site. Panels were also deployed in August 1983 at three other locations in the Chesapeake Bay region (Morgantown, Point No Point, Solomons) to compare their fouling rate with that at Chalk Point. A total of 22 species were found on all panels. Two antifouling technologies (copper-nickel screen construction and air backflushing) were tested at the Chalk Point site. A third antifouling technology, organotin paints, was tested at both the Solomon's and Chalk Point sites. The results are given in the report.
