Treatment of Biofouling in Internal Seawater Systems - Phase 2
Abstract
Biofouling in the internal seawater systems of vessels is considered to pose a high risk for the introduction and/or translocation of marine pests and, as part of Australia's new National System for the Prevention and Management of Marine Pest Incursions, options for treating such biofouling are needed. Mussels are of particular concern. In this study, a range of chemicals, including vinegar, detergents, disinfectants, bleach, descalers, pipework treatments and freshwater, were tested on the southern Australian blue mussel, Mytilus galloprovincialis planulatus. The effectiveness of descalers in digesting mussel shells was assessed, and the toxicity of other treatments determined in 6 and 14 h (hour) exposures. The most effective treatments were two disinfectants, which both contained the active benzalkomum chloride. 14 h treatments with disinfectants of this type were concluded to be the most effective means of killing mussels. However, the toxicity and environmental acceptability of these chemicals warrant investigation in regard to discharge and disposal of treatment solutions.
