FilmTech™ Membrane SW-30-4040

Key Features:

• FilmTech Membranes offer the highest productivity while maintaining excellent Salt Rejection.

• FilmTech SW30 Membrane Elements have the highest flow rates available to meet the water demands  

   of both sea-based and land-based declinators.

• FilmTech SW30 elements may also be operated at lower pressure to reduce pump size, Cost and

   Operating expenses.

• Improved FilmTech Seawater Membrane combine with automated, precious element fabrication

   Result in the most consistent product performance available

Key Application:

• Commercial Solutions.
