Recommendations for Evaluating Multiple Filters in Ballast Water Management Systems for US Type Approval

Abstract

International, national, and regional efforts have been initiated to address the introduction of aquatic nuisance species (ANS) from commercial ships ballast water and sediment. To meet these stringent discharge standards, most vessels will install a ballast water management system(BWMS). Of the BWMS currently installed on vessels, or those in development, most treat water using a combination of physical separation (usually filtration) followed by a disinfection step (e.g., electrochlorination or ultraviolet [UV] radiation). Further, some BWMS manufacturers specify multiple filtration system options to accommodate different flow ranges or allow filters to be sourced from multiple vendors (thus reducing the risk associated with maintaining a single source of supply). Each filter may, however, affect performance of the downstream treatmentor the overall systemin a different way. This report provides guidance to the US Coast Guard (USCG) as they consider type approval (TA) applications for BWMS that specify the use of multiple filters.
