F -- SOURCES SOUGHT FOR MICELLAR-ENHANCED ULTRAFILTRATION (MEUF) TO RECOVER AND CONCENTRATE SURFACTANTS FROM A DILUTE AQUEOUS MICELLAR SOLUTION SOL N47408-97-R-2304 NOT A SOLICITATION DUE 123096 POC Contract Specialist, PAULETTE K. PETERSON, 805-982-5081 The Navy is seeking a source to investigate the use of micellar- enhanced ultrafiltration (MEUF) to recover and concentrate surfactants from a dilute aqueous micellar solution. The respondent must be capable of performing continuous bench-scale experments to achieve up to 90 percent recovery and 2 to 5-fold concentration of surfactants, design and assemble a 1 to 5 gpm MEUF unit for field use, and assist in the operation of the MEUF unit in a field demonstration. The respondent will be working in clos collaboration with a team of investigators on a 3-year project that will include the following tasks: in-situ application of surfactants for DNAPL removal, separation of DNAPL from the surfactants, and re-injection of the recovered and concentrated surfactants. Participation in the surfactant selection process as well as the post-demonstration evaluation of results is expected. The respondent must meet the following quaifications: (a) Over 10 years research experience on surfactants as well as MEUF for contaminant removal; (b) At least two completed field projects using MEUF to recover and remove surfactants and contaminants; (c) A minimum of three years experience with echniques to separate TCE and other chlorinateds from surfactants (such as pervaporation, extraction, distillation, and stripping techniques); and (d) Prior assembly of at least one pilot-scale MEUF unit for field demonstration. Prior participation in surfactant projects for subsurface NAPL removal is highly desired. Universities with the above qualifications are also encouraged to apply. Respondnts must provide evidence of research and field experiences in the form of references (at least three) and pertinent publications. Respondents providing incomplete experience information and supporting documentation will not be considered. Respondents mustsubmit references, publications, and other supporting documentation of capabilities to: DEPARTMENT OF THE NAVY, CBC CODE 272311 BLDG 41, 1000 23RD AVENUE, PORT HUENEME, CA 93043- 4301. Deadline for receipt of response is December 30, 1996. (0346)
