99 -- TECHNOLOGIES, PROCEDURES, CONCEPTS, SYSTEMS, ALTERNATIVE MATERIALS OR DEVICES TO REPLACE, MINIMIZE OR PROCESS POLLUTANTS PRESENT IN DISTILLATION & REVERSE OSMOSIS BRINE DISCHARGE SOL N00167-99-SS-0097 POC Sheila Riggs (301)227-5198 In support of the development of Uniform National Discharge Standards (UNDS), the Carderock Division, Naval Surface Warfare Center (CDNSWC) seeks sources to provide technologies, procedures, concepts, systems, alternative materials, or devices to replace, minimize, process, or otherwise control pollutants present in distillation and reverse osmosis brine discharge generated by Armed Forces vessels. This intermittent discharge is the concentrated seawater (brine) produced as a byproduct of the processes used to generate freshwater from seawater. Distillation plants boil seawater, and the resulting steam is condensed into high-purity distilled water. The remaining brine that is not evaporated is discharged overboard. Reverse osmosis systems separate freshwater from seawater using semi-permeable membranes as a physical barrier, allowing a portion of the seawater to pass through the membrane as freshwater and concentrating the suspended and dissolved constituents in a saltwater brine that is subsequently discharged overboard. Distillation and reverse osmosis brine may include copper, iron, lead, nickel, zinc, phosphorus, and various forms of nitrogen. Potential offerors are requested to respond with technical documentation supporting the technology, procedure, concept, system, alternative material, or device. The proposed solution must demonstrate the ability to control, reduce, or eliminate the discharge and some or all of its constituents listed above. Additional information should include, but not be limited to, the following: process description, current commercial or military applications, specific applications in the marine environment (including customer references/ship class/name), processing rate capability, normal operative and maximum permissible pressures, physical size, total dry and wet weights, maintenance requirements, operational manning requirements, power consumption per hour of operation, utilities required, secondary wastestreams generated, and equipment performance and testing results. Technical, industry, or professional society certifications or endorsements should be provided, if available. A summary of agents or contaminants which could potentially interfere with the operation and performance of the technology is also requested. In evaluating the submissions, DoD will consider the following criteria: (1) the nature of the discharge that the technology, procedure, concept, system, alternative material, or device is designed to process, (2) the effectiveness of the technology, procedure, concept, system, alternative material, or device at mitigating the environmental effects of that discharge, and (3) the technology, procedure, concept, system, alternative material, or device's cost, practicability and effect on operations or operational capability when installed and used on a vessel. This synopsis is for information purposes and to identify potential technologies and offerors. This sources sought announcement does not constitute an RFP and does not obligate the government in any way to purchase or test any of the potential solutions offered. Further, it does not commit the government to pay for any proposal costs in response to the sources sought announcement. Submit responses for this synopsis to Naval Surface Warfare Center, Attn: Sheila Riggs (Distill), Code 633, 9500 MacArthur Boulevard, West Bethesda, Maryland 20817. Responses to this sources sought announcement are due within 45 calendar days of the date of publication. For additional technical information on distillation and reverse osmosis brine discharge, refer to the nature of discharge (NOD) report available at http://206.5.146.100/n45/doc/unds/unds.html.
