46 -- WATER PREFILTERS SOL JM96-003 POC Jeff Marshall, LSO-360, Kennedy Space Center, FL 32899. Lockheed Martin Space Operations (LMSO), a NASA Prime Contractor at Kennedy Space Center, FL (KSC), seeks sources capable of providing design, fabrication, assembly, cleaning, painting, testing and delivery of two (2) cooling tower condensor water prefilters. Both units are to be delivered in FY96. Each unit shall have the ability to accept water from the cooling tower and retrun with a permeate not to exceed 1.3 mg/1 Ca., 24 mg/1 Na., 15 mg/1 Hc03, 3 mg/1So4, 28 mg/1 Si02 and 0 mg/1 K, Mg., NH4, Ba., Sr., Co3, F, and No3. The TDS is not to exceed 77 with a pH in the range of 4 - 5. Permeate flow shall be 75 - 80 gallons per hour (GPH). Feed water entering the prefilter is expected to be potable water supplied by the Cocoa, FL municipal water system that has been cycled up to a maximum of 10 cycles. Potential prefilter supply is expected to be as follows: 277 mg/1 Ca, 8 mg/1 Mg., 1050 mg/1 Na., 1010 mg/1 Cl., 140 mg/1 Si02, and 0 mg/1 K, NH4, Ba., Sr., C03, F, and No3. TDS is expected to be 4125 mg/1 with a pH range of 5.5 - 6.5. Replacement elements shall have a life expectancy of 3 - 5 years with less than 5% loss in operating efficiency. The prefilter shall be capable of accepting on/off commands from a local Programmable Logic Controller (PLC) as well as provide data to the PLC. Data shall include, but not be limited to, operating pressure, filter media health, permeate output in GPD and Langelier Sat. iIndex. Any chemicals to be added to the water shall be approved by LMSO Engineering, automatically input and monitoried. MSDS sheets shall be provided for all chemicals expected to be used. It shall be the responsiblity of the successful offeror to obtain samples of the Cocoa water as well as water from the cooling tower basin in such quantity as required to support design and fabrication of the prefilter and to assure successful operation. This synopsis is for the sole purpose of identifying prospective sources and does not commit LMSO to make an award, nor to reimburse costs of data submitted in response. Interested firms should submit indications of itnerest to reach LMSO by 020296. Also submit data, in duplicate, of company capabilities, experience in this or related field, and such other data as may indicate a bona fide capability to perform the requirements described above.
