FilmTec membranes offer reliable performance with a 99.7% salt rejection rate and can operate at pressures up to 1,000 psi. They come in over 25 configurations, including SW30, BW30, and NF series, designed for industrial water treatment.
Water treatment experts require membrane elements with verified specifications and reliable performance data. DuPont FilmTec membranes provide documented operational parameters including precise flow rates, rejection percentages, and pressure tolerances that enable accurate system design and predictable outcomes. Industrial operators select FilmTec membranes based on 3 critical performance factors: polyamide thin-film composite construction, automated precision fabrication processes, and consistent temperature ranges up to 113°F (45°C).
FilmTec membrane technology operates across pH ranges from 2-11 for continuous operation and 1-13 for cleaning cycles. These specifications support municipal water treatment facilities processing over 10 gpm (2,300 L/h) of permeate and seawater desalination plants requiring maximum operating pressures. The SW30 series handles seawater applications with flow rates optimized for both sea-based and land-based desalinators, while BW30 series membranes reduce operating pressures by 33% for brackish water treatment systems.
How Do DuPont FilmTec Membrane Technologies Deliver Superior Performance?
DuPont FilmTec membranes achieve superior performance through polyamide thin-film composite construction, automated precision fabrication, and testing at maximum operating pressures of 1,000 psi for seawater and 600 psi for brackish water applications.
FilmTec membrane construction utilizes polyamide thin-film composite technology with automated fabrication processes that ensure precision and consistency across 4 performance categories:
- Operating temperature range: 113°F (45°C) maximum across all series including SW30, BW30, and NF configurations
- pH tolerance: Continuous operation 2-11, cleaning cycles 1-13 for chemical compatibility
- Pressure capabilities: SW30 series 1,000 psi (69 bar), BW30 series 600 psi (41 bar) maximum operating pressure
- SDI tolerance: Maximum 5 for consistent feed water quality requirements
The SW30 series handles seawater desalination with flow rates optimized for both sea-based and land-based operations. These membranes maintain excellent salt rejection while providing the highest productivity available in the market. BW30 series delivers 33% lower pressure requirements for brackish water treatment, reducing pump size, operational costs, and energy consumption.
Dupont FilmTec membrane elements undergo automated precision element fabrication that results in consistent product performance. The manufacturing process combines improved seawater membrane technology with quality control systems that enable predictable system design parameters. Industrial operators select FilmTec membranes based on documented flow rates, rejection percentages, and operational tolerances that support large-scale municipal and industrial water treatment systems processing over 10 gpm (2,300 L/h) of permeate.
What Are the Key DuPont FilmTec Membrane Series Available?
Water treatment professionals utilize 5 primary FilmTec series: SW30 for seawater, BW30 for brackish water, NF90/NF270 for nanofiltration, ECO series for energy efficiency, and XLE for low-energy applications.
| Series | Application | Max Pressure | Key Feature |
|---|---|---|---|
| SW30 | Seawater | 1,000 psi | Highest flow rates |
| BW30 | Brackish water | 600 psi | 33% lower pressure |
| NF90/NF270 | Nanofiltration | 600 psi | Selective contaminant removal |
| ECO | Energy efficiency | 600 psi | High salt rejection, low pressure |
| XLE | Low energy | 600 psi | Cold water productivity |
Each FilmTec series targets specific water treatment challenges. SW30 elements operate at maximum 1,000 psi with excellent salt rejection for desalination applications including sea-based and land-based facilities. BW30 series delivers salt separation for brackish water at 600 psi maximum pressure with 33% lower pressure requirements. NF90 and NF270 provide selective removal of divalent ions and organic compounds while maintaining high permeability for utility applications. ECO series membranes combine high salt rejection with low pressure operation for enhanced fouling protection. XLE membranes produce water quality at very low applied pressure, especially effective in cold water conditions.
