46 -- THREE MONTH LEASE OF PILOT SIZE MICRO- AND ULTRA-FILTRATION SYTEMS FOR TESTING SOL N47408-00-T-0101 DUE 111899 POC Ms. Naomi Melendez, Contracts, (805)982-5095, fax 3015, E-mail melendeznm@slc.navfac.navy.mil LEASE OF PILOT SIZE MICRO- AND ULTRA-FILTRATION SYSTEMS. This is a combined synopsis/solicitation, FAR Subpart 12.6. This announcement N47408-00-T-0101 constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. Multiple awards will be made on an unrestricted, competitive, negotiated basis. The Naval Facilities Engineering Service Center (NFESC) in Port Hueneme, CA is interested in a three-month lease of pilot sized filtration units, used as a pretreatment device to a reverse osmosis (RO) system. The military uses mobile desalination systems called either reverse osmosis water purification units (ROWPU) or tactical water purification systems (TWPS) to produce potable water from a variety of natural water sources ranging from fresh to seawater. Media and cartridge filters are now used as the pretreatment stages on the ROWPUs but the overall logistics burden and life cycle costs associated with these technologies have proven to be relatively high especially when treating poor quality feed waters. More advanced separation processes such as micro-filtration (MF) and ultra-filtration (UF) offer the promise of better performance and reduced logistics requirements. The focus will be documentation of technical performance of a variety of MF/UF systems on a seawater source. Our intent is to lease a variety of MF and UF pilot units, although other separation processes may be considered, for a THREE MONTH period to obtain operational, maintenance, and reliability data while conducting a 1000 hour performance test. This information will help determine the suitability of various systems for use as a pretreatment stage for a reverse osmosis process. The technical testing will be conducted at the Seawater Desalination Test Facility (SDTF) located at NFESC, Port Hueneme, California. The turbidity of the seawater is expected to range from 0.5 to 2.0 NTU. A portion of tests will be conducted on a 5 to 10 NTU challenge water made from seawater and Arizona fine test dust. The feed water expected temperature range will be between 10 to 20 degrees Celsius with pH expected to range from 7.5 to 8.0. Candidate systems should be nominally rated between 5 and 30 gallons per minute (GPM), should use a membrane with a pore size 0.2 microns or less. Each pilot system should be capable of operating unattended (24 hrs/day, 7 days/week) on a seawater feed source with minimal downtime for routine maintenance on the system. The tests will be conducted for a period of up to 1000 hours. The piping, pumps, and other materials on the pilot units must be compatible with the seawater feed source. Electrical service currently available at the SDTF is 208 VAC, three phase power. Interested companies should provide their proposals for leasing their pilot unit and address the following areas: Description and technical characteristics of pilot unit (membrane type, membrane area, etc.), Lease terms, monthly costs, and shipping costs for pilot unit, System availability including lead time needed to obtain pilot unit, Level of technical support provided by manufacturer, Piping and instrumentation diagram for pilot unit, Piping connections required for installation (inlet, outlet, and backwash), Pilot unit electrical, air and pre-filtration requirements, Prior test data especially if pilot has been operated on seawater feed source, System weight and dimensions, Any special tools and equipment needed for operation of pilot unit. It is expected that up to 10 systems will be leased for testing with multiple awards being issued anytime through 1 June 2000. The government reserves the right to terminate any lease early. Our intent is to complete testing and evaluation by September 2000. Vendors who do not respond to this announcement may be considered ineligible to receive future awards in the short-term for like-kind equipment. The contractor pays shipping FOB destination to CBC Port Hueneme; the government pays return shipping. The government requires two weeks after the three month testing in which to return the pilot size system. Candidate pilot units should be clearly marked as property of individual companies. The data and test results generated by this program remain the property of the government. Individual companies will be provided test results from their systems provided the information is for internal use only and not used for advertising or marketing purposes. Awards will be made under Simplified Acquisition Procedures on a Standard Form 1449. This is a combined synopsis/solicitation. Prospective offerors will receive no other paperwork. FAR provisions 52-212-1 and 52.212-2, Evaluation-Commercial Items, apply. Evaluation criteria will be technical capabilities, past performance, and price. Offers are requested to include a completed copy of FAR Provision 52.212-3, Offeror Representations and Certification-Commercial Items, with the offer. FAR clause 52.212-4, Contract Terms and Conditions-Commercial Items, applies as well as FAR clause 52.212-5. The following FAR clauses cited in 52.212-5 apply: 52-222-21, 52.222-26, 52.222-35, 52.222-36, 52.222-37, 52.225-3. FAR site is: www.arnet.gov/far/. Proposals shall be received by November 18, 1999 at the NAVFAC Contracts Office, Code 80, Bldg 41, 4111 San Pedro Street, Port Hueneme, CA 93043-4410, attention Ms. Naomi Melendez, or by fax (805) 982-3015, or E-mail melendeznm@slc.navfac.navy.mil with a copy to NFESC, Attn: Mr. Bill Varnava, 1100 23rd Ave, Code 32, Port Hueneme, CA 93043.
