This is a Brand Name requirement for 3M Liqui-Flux Ultra Filtration Membrane filters #W20-08N and flanges. TIME IS OF THE ESSENCE Ultra Filter Membrane Filters by 3M are used in the Oily Water Treatment System (OWS) for the 1247E facility. The design and operation of the system and performance is based on the use of these 3M Liqui-Flux UF Membrane filters only. Each day the filters are not in service, a pump and haul operation is required at additional cost to the Government as the OWS system is inactive without the #M UF Membrane filter installed. Shipping from the Vendor to: LaRC Distribution Center, 4 South Marvin Street, Hampton, VA 23681 must be included. 3M UF Membrane Specifications: Provide three 3M Ultra Filtration Membrane Filters and nine each flanges complying with the following: 1.
