Different series of Fimtec Membranes
For seawater desalination applications, American-made FilmTec SW membrane elements are widely utilized. Currently, one of the most effective solutions for supplying potable water in regions lacking access to high-quality drinking water is the treatment of seawater or saline groundwater. FilmTec SW membranes are approved by the World Health Organization (WHO) in terms of enhancing water quality standards. These membranes exhibit high resistance to fouling, which consequently results in extended operational lifespan.
The following are some key models of FilmTec SW membrane elements:
- FilmTec 8-inch seawater membrane, model SW30XLE-400:
Designed for high-flux operation with exceptional salt rejection accuracy. Its implementation significantly contributes to reduced energy consumption. - FilmTec 4-inch seawater membrane, model SW30HRLE-4040:
With dimensions of 4 × 40 inches, this element offers efficient energy performance, leading to lower operational expenditures (OPEX) in treatment systems. - FilmTec 8-inch seawater membrane, model SW30HR-380:
- Capable of boron rejection in compliance with WHO standards, while also contributing to reduced brine discharge in industrial desalination systems.
- FilmTec 4-inch seawater membrane, model SW30-4021:
Delivers effective filtration performance even at relatively low feed pressures, thereby minimizing or eliminating the need for high-pressure pumping systems. - FilmTec 8-inch seawater membrane, model SW30HRLE-400:
Provides highly optimized desalination performance, alongside reduced energy consumption when integrated into system designs. - FilmTec 8-inch seawater membrane, model SW30HRLE-400i:
Enables high-purity seawater filtration with improved energy efficiency and optimized operational performance.
2-FilmTec TW Membranes (Tap Water Series)
These membranes are specifically designed for municipal (tap water) filtration applications. FilmTec TW membrane elements are commonly used in residential and semi-industrial water purification systems. They offer high-precision removal of a broad spectrum of contaminants present in municipal water supplies. However, the production capacity of FilmTec TW membranes is significantly lower compared to SW (seawater) and BW (brackish water) membrane types.
3-FilmTec BW Membranes (Brackish Water Series)
“BW” stands for Brackish Water, and accordingly, FilmTec industrial membrane elements in the BW series are specifically engineered for the treatment of brackish water sources. These membranes are capable of removing a wide range of contaminants, including nitrates and nitrites, arsenic, mercury, dissolved salts, salinity, and other impurities. They can also be effectively applied in municipal water treatment, significantly enhancing overall water quality. In fact, these membranes provide contaminant rejection down to approximately 0.0001 microns, corresponding to nanofiltration/reverse osmosis-level separation performance.
FilmTec BW membrane elements are widely used across various industries, including pharmaceutical manufacturing, bottled mineral water production, textile processing, boiler and steam generation systems, agricultural desalination units, and HVAC (heating, ventilation, and air conditioning) systems.
FilmTec BW membranes are available in multiple configurations, with the most widely used and commercially successful models listed below:
- FilmTec 8-inch membrane, model BW30-400:
Highly compatible with a broad range of reverse osmosis (RO) systems and recognized as one of the most widely utilized FilmTec membrane elements. - FilmTec 4-inch membrane, model BW30-4040:
Capable of producing approximately 9,000 liters per day (LPD) of treated water, while meeting established quality and certification standards. - FilmTec 8-inch membrane, model BW30HR-440:
Engineered with enhanced resistance to scaling and fouling, resulting in extended service life and improved operational reliability. - FilmTec 8-inch membrane, model BW30-400/34i:
Designed with high fouling resistance under varying feedwater conditions, minimizing system downtime and reducing operational expenditures. - FilmTec 8-inch membrane, model BW30-365:
Offers reliable filtration performance with maximized membrane lifespan, contributing significantly to reduced maintenance costs in industrial water treatment systems.
