Reverse osmosis (RO) membranes for seawater.

FILMTEC ™ seawater membranes are composed of spirally wound polyamide thin film that are resistant to biofouling (biological contamination). They are built with automated technology equipment superior to that used in the market, which results in a level of precision that is impossible to achieve with manually wound elements.

Benefits of Filmtec Seawater Membranes:

  • FILMTEC ™ Dirt-resistant Elements low pressure reduction in permeate flow, producing higher efficiency, more uniform net driving pressure and more uniform distribution of permeate flow.
  • FILMTEC ™ dirt resistant elements are very durable and can be cleaned at pH 12. They are also very resistant to bacteria. These features extend the time between cleanings and reduce cleaning costs.

Industrial reverse osmosis (RO) membranes.

FilmTec ™ RO are spiral wound thin film composite polyamide membranes. Generally, a spiral wound configuration means lower replacement costs, simpler plumbing systems, easier maintenance, and greater design freedom than other configurations such as hollow fiber, plate-and-frame, and tubular module designs.

Filmtec uses the industry's most advanced automated technology in the manufacture of reverse osmosis (RO) elements, resulting in maximum uniformity and minimizing gaps between elements. Rigorous and extensive quality testing ensures that FilmTec ™ elements meet a high manufacturing standard.

Nanofiltration Reverse Osmosis Membranes (NF).

FilmTec ™ NF membranes provide excellent performance for a wide variety of applications in terms of rejection of salts and organic matter, and resistance to fouling. FilmTec ™ elements can operate in a pH range of 2 to 11, are resistant to compaction and are suitable for temperatures up to 45 ° C. They can be effectively cleaned at pH 1 and pH 13, depending on the temperature.
