46 -- TEAM WATER PURIFICATION FILTER SOL M67854-95-R-2160 DUE 060195 POC JEFF CAMPBELL, CODE CTQ-3JC, (703) 752-9344 EXT.234. The following is a modification to the CBD announcement regarding the Team Water Purification Filter, which was dated February 10, 1995. The Marine Corps Systems Command intends to procure a Non-Developmental Item (NDI) Team Water Purification Filter (TWPF). This competitive procurement shall be reserved as a Small Business Set-aside, with a Standard Industrial Classification (SIC) code of 3589 and a size of 500 employees. The TWPF shall be a single raw fresh water treatment unit employed during field use by 4 to 6 military servicemen. The TWPF shall purify contaminated fresh water from any available source normally found in geographical locations in which the United States can expect to employ military forces. The TWPF shall protect personnel from cyst- forming protozoa and bacteria, making the water safe for human consumption, while reducing the quantity of turbidity that is common in raw water sources. It is intended that the TWPF shall, at a minimum, have the capability to be used as a pretreatment to the use of the standard military water purification tablet, NSN 6850-00-985-7166, in order to protect the intended user from viruses as well as the previously mentioned microbiological hazards. Together, TWPF and the water purification tablet shall provide complete disinfection of all water-borne pathogenic microorganisms so that personnel can consume the water without becoming ill. Technology capable of combining the filtration process and complete disinfection process into one mechanical procedure is acceptable. Principal (Required) Characteristics: (a) The TWPF shall remove or destroy a minimum of 99.9% (3 log reduction) of cyst-forming protozans (Cryptosporidium parvum). ( b) The TWPF shall remove or destroy a minimum of 99.9999% (6 log reduction) of bacteria (Klebsiella terrigena). (c) The TWPF shall reduce turbidity to 0.5 Nephelometric Turbidity Units (NTU) or less in the effluent produced by the purification device for 95% of the measurements taken for a total production of 84 gallons of ''purified'' water when the source water has a turbidity of 60 NTUs. (d) The TWPF shall be capable of supplying a minimum of 84 gallons of purified water (0.5 NTUs or less) before replacement of filter element(s) is required when filtering source water with turbidity level of 60 NTUs. (e) The TWPF shall be compatible with the standard military issue canteen (NSN 8465-01-115-0026) and shall be capable of easily transferring product water to a canteen without spillage. (f) The water purifier shall provide the capability of absolute fail-safe operation by verifying to the operator (i.e. a visual or physical signal) that the purification process is meeting established water quality and that the filter media has neither reached the end of its operating life, nor suffered from catastrophic failure (i.e., suffered from damage to the filter media not normally visible from the exterior of the device... such as a small crack in the filter media, or filter ''breakthrough'' caused by excessive cleaning to all or part of the filter media). (g) Over- pressurization of the water purifier/filter media shall not cause the unit to fail (i.e. permit micro-biological hazards or turbidity above 0.5 NTUs to be present in the product water) without a positive indication to the operator. Therefore, the use of a pressure relief valve to reduce flow through the filter media is highly recommended. (h) The TWPF shall not exceed 2 pounds, with 1.5 pounds desired. These weights include the operational filter, spare filter and equipment, case and all peripherals required for operation/cleaning. (i) The size of the TWPF shall not exceed the following limitations: for a Non-cylindrical Unit (i.e. a rectangular or any shape other than cylindrical) device length of 12 inches, device width of 4 inches, and device height of 4 inches. For a cylindrical unit, the following dimensions shall not be exceeded: device length 12 inches and device diameter 4 inches. (j) It is desired that the TWPF remove or destroy a minimum of 99.99% (4 log reduction) of virus (Poliovirus type 1/Rotavirus SA11 as a mixed viral culture). The TWPF shall accomplish this by processing the source water only one time to remove or destroy a minimum of 99.99% (4 log reduction) of virus (Poliovirus type 1/Rotavirus SA11 as a mixed viral culture) without the addition of standard military issue iodine tablet. Multiple ''passes'' through the device shall not be acceptable. Vendors requesting a copy of the solicitation for this procurement should submit a request to the following address by no later than 1 JUN 95. The request should be mailed to: Commander, ATTN CTQ 3JC, MARCORSYSCOM, 2033 Barnett Avenue, Suite 315, Quantico VA 22134-5010. NOTE: Vendors may be required to submit three product samples, at no cost to the Government, for technical evaluation by the Government. See Numbered Note 22. (0102)
