Filmtec (NF-4040) NANO Filtration Membrane 6,800 GPD 8''X40''

Description
Related Info.

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.
