  Performance Evaluation of Type 1 Marine Sanitation Devices (EPA/600/R-10/008) January 2010


 Cover: Performance Evaluation of Type 1 Marine Sanitation Devices

The performance tests in this report evaluated the effectiveness of two Type I marine sanitation devices (MSDs) in reducing fecal coliform bacteria and visible floating solids. In addition, the study also included testing for enterococci and Escherichia coli indicators, biochemical oxygen demand, total suspended solids, and nutrients (ammonia, total Kjeldahl nitrogen, nitrate/nitrite, and total phosphorous) in both the influent to and effluent from the devices. The Type I MSDs underwent performance evaluation testing using procedures for the Sewage Processing Test contained in the U.S. Coast Guard's (USCG) MSD certification requirements at 33 CFR 159.121. Testing was not performed for Type I MSD certification, as both tested devices were already certified by the U.S. Coast Guard (USCG) to meet EPA performance standards at the time of testing. The purpose of this report was to provide objective performance data on the two tested devices so that consumers, developers, and regulators can make informed decisions about purchasing and applying the technology in these products.
