PERFORMANCE EVALUATION OF TYPE I MARINE SANITATION DEVICES
Eastern Research Group, Inc. PERFORMANCE EVALUATION OF TYPE I MARINE SANITATION DEVICES. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-10/008, 2010.
To Share Research Results
This performance test was designed to evaluate the effectiveness of two Type I Marine Sanitation Devices (MSDs): the Electro Scan Model EST 12, manufactured by Raritan Engineering Company, Inc., and the Thermopure-2, manufactured by Gross Mechanical Laboratories, Inc. Performance tests were conducted to evaluate the effectiveness of Type I MSDs in reducing fecal coliform bacteria and visible floating solids (VFS). In addition, the performance evaluation described herein also included testing for enterococci and Escherichia coli (E. coli) indicators, biochemical oxygen demand (BOD5), total suspended solids (TSS), and nutrients (ammonia, total Kjeldahl nitrogen (TKN), nitrate/nitrite, and total phosphorous) in both influent to and effluent from the devices. The performance evaluation tests were conducted under the direction of EPA through the support of Eastern Research Group, Inc. (ERG) and ERG’s subcontractor, NSF International (NSF). The purpose of this report is to provide objective performance data on these technologies so that consumers, developers, and regulators can make informed decisions about purchasing and applying the technology in these products.
