| Filmtec (NF-4040) NANO Filtration Membrane 6,800 GPD 8"X40" |
 FILMTEC NF membrane elements are designed for process applications where a separation of solutes is desired. "NF" is a durable membrane designed to reject organics with a molecular weight above 200 while passing monovalent salts. FILMTEC NF membrane elements replace NF45 elements in a variety of applications such as desalting organic compounds, acid processing, metal recovery from waste streams, and antifreeze recovery. Product Name Nominal Active Surface Area ft2 (m2) Stabilized Salt Rejection (%) Minimum Salt Rejection (%) FILMTEC NF-4040 82 (7.6) 99 98.0 Permeate flow and salt rejection based on the following test conditions: 2000 ppm MgSO4, 130 psig (8.9 bar), 77�F (25�C), pH 8, 15% recovery. Target water flow rates for new elements are: 1950 gpd (7.4 m3/d). Membrane flow on specific process streams will vary as a function of the feed. For the purpose of improvement, specifications may be updated periodically. Price: 1250.00 |
