F -- SOURCES SOUGHT FOR SONOLYSIS FOR NAVY INDUSTRIAL WASTEWATER TREATMENT PLANTS SOL N47408-97-R-2301 NOT A SOLICITATION DUE 123196 POC Contract Specialist, PAULETTE K. PETERSON, 805-982-5081 This is a SOURCES SOUGHT ANNOUNCEMENT for INFORMATION ONLY. This is NOT a solicitation announcement. NO AWARD WILL RESULT FROM THIS ANNOUNCEMENT. THE GOVERNMENT WILL NOT RESPOND TO ANY REQUEST FOR A SOLICITATION. NO TELEPHONE CALLS WILL BE ACCEPTED. Navy tasks, such as electroplating, paint stripping, boiler cleaning, and metal cleaning/degreasing, generate wastewaters containing toxic organic contaminants that must be pre-treated prior to discharge by Navy Industrial Wastewater Treatment Plants (IWTPs). These IWTPs must meet Federal discharge limits for Total Toxic Organics (TTOs) which are determined by the sum total of the concentrations of specific organic contaminants whose individual concentrations exceed 0.01 ppm. Effective and affordable treatment technologies need to be sought for complete mineralization of these toxic organics due to the more stringent regulations imposed following the amendment of the Clean Water Act. NFESC is seeking information from companies, universities, or other government agencies that operate bench/demonstration scale ultrasonic irradiation (sonolysis) systems for industrial wastewater treatment. NFESC is seeking information on demonstration hardware that can test Navy wastestream samples in varying concentrations of contaminants and that this hardware must be capable of scaling to the Navy's needs in an integrated zero discharge IWTP. Previous technology assessments have identified ultrasonic irradiation as technologically feasible for the Navy's IWTP TTOs requirement. In order to be economically viable, NFESC is seeking information on improvements in sonolytic reactor design to lower the energy intensive cost of current commercial systems while increasing organic destruction efficiencies. NFESC is seeking sources for alternative reactor geometry with larger radiating surfaces, such as a high intensity flat plate reverberatory sonicator, rather than the conventional direct immersion probe reactor. For RDT&E testing, the reactor must accommodate variable frequency settings (40-500 kHz and 1.0 mHz) and be capable of running in a continuous mode. Testing will also require the investigation of optimal sparging gases for the Navy contaminants so ports must be part of the operating system. In addition, NFESC requires that the demonstrator of this advanced reactor design have familiarity with the reactor's sonolytic chemistry, i.e., with respect to intermediates and reaction by-products that are generated during treatment to ensure that residuals more toxic than the starting Navy contaminants are not generated. Respondents should provide the following information: Name/address or company, point of contact with phone/fax number and narrative description of ultrasonic hardware that can be operated as required in this announcement. At a minimum include power and frequency range, treatment capacity in gpm, and lists of organic wastes treated to date with reaction rates and destruction effectiveness for these wastes. All proprietary information that is not to be disseminated in Government documents must be clearly identified. Responses to this announcement must be mailed to: Department of the Navy, CBC Code 272311 Bldg. 41, 1000 23RD Avenue, Port Hueneme, CA 93043-4301. Deadline for receipt of response is 31 October 1996.(0290)
