Nanofiltration

FILMTEC Nanofiltration Elements Offer Solutions for Solute-Specific Separations Including Softening, Pesticide and Organic Removal

In every application, with every customer, FilmTec seeks to offer the optimum balance of quality performance, reliability, and cost. And with the unique capability of FilmTec’s nanofiltration (NF) membranes we enable you to customize the water composition you require as well.

FILMTEC™ nanofiltration membranes have a pore size in the order of nanometers (10 angstroms). Nanofiltration membranes typically operate at less than 100 psi (7 bars). FilmTec offers a portfolio of nanofiltration membranes that can remove organics with molecular weights greater than 200 (e.g. Total Organic Carbon (TOC) and disinfection by-products) while allowing varying amounts of salt and hardness passage.

FILMTEC NF90 Elements: Removal of TOC, nitrates, pesticides, herbicides, hardness, iron, salts.

FILMTEC NF270 Elements: Removal of color, TOC, medium to low calcium passage, high salt passage.

FILMTEC NF200 Elements: Removal of TOC, atrazine, medium calcium passage, medium to high salt passage.

FILMTEC NF Elements: Purification of non-water process streams and concentration of valuable substances.
