Seawater Desalination

FILMTEC Membranes Continue to Lower the Cost of Seawater Desalination

"If we could ever competitively, at a cheap rate, get fresh water from saltwater,…(this) would be in the long range interests of humanity which could really dwarf any other scientific accomplishments." John F. Kennedy, September 22, 1961

FilmTec is helping enable this vision with new products, technology and strategies for lowering the cost of desalinated water.  Today FilmTec makes available the new FILMTEC™ SW30XLE-400i element, a reverse osmosis (RO) element with the lowest energy requirement in the industry to deliver the lowest total cost of water across a wide range of seawater desalination applications. In addition, our new FILMTEC SW30HR LE-400i element can reduce your desalination costs by as much as 20%, depending on whether you are seeking lower pressure, higher productivity or a system with fewer elements.

Both of these products also feature the new iLEC™  interlocking endcaps, an innovative element coupling technology that further reduces system costs and minimizes the risk of o-ring leaks that lead to degraded water quality.

FILMTEC Seawater Elements

FILMTEC SW30XHR-440i	FILMTEC SW30XHR-440i element is the highest rejection seawater RO element in the DOW FILMTEC element portfolio, enabling stringent water quality requirements to be met reliably with single pass seawater systems in most situations.
FILMTEC SW30ULE-440i	FILMTEC SW30ULE-440i is an element of choice for low to medium salinity and temperature waters, for permeate staged systems for stringent water quality targets, and for high feed salinity brackish water applications. It has the highest sustainable flow rate available in the industry, coupled with high rejection of NaCl and boron.
FILMTEC SW30XLE-440i	FILMTEC SW30XLE-440i offers medium salinity and medium temperature feed waters an advanced combination of high productivity and high rejection through extra-low energy consumption and single-pass design. It is also an ideal choice for two-pass seawater designs or high salinity brackish water applications.
FILMTEC SW30HRLE-440i	FILMTEC SW30HRLE-440i element offers sustainable lower lifecycle cost for medium and high salinity feedwaters by combining high rejection and low energy performance with the highest active area and thickest feed spacer of the Dow membranes.
FILMTEC SW30XHR-400i	FILMTEC SW30XHR-400i element is the highest rejection seawater element in the FILMTEC element range, enabling stringent water quality requirements to be met with single pass seawater systems in most situations.
FILMTEC SW30ULE-400i	FILMTEC SW30ULE-400i is an element with one of the highest flow rates in the industry, and high rejection of NaCl and boron.
FILMTEC SW30XLE-400i	FILMTEC SW30XLE-400i offers an unequalled combination of productivity and rejection. This is the lowest energy seawater element available on the market, enabling lowest operation cost.
FILMTEC SW30HRLE-400i	FILMTEC SW30HRLE-400i element offers very high productivity and rejection, enabling the lowest total cost of water for seawater desalination.
FILMTEC SW30HRLE-400	FILMTEC SW30HRLE-400 element offers very high productivity and rejection, enabling the lowest total cost of water for seawater desalination.
FILMTEC SW30HR-370/34i	FILMTEC SW30HR-370/34i is a durable, high-rejection, high-productivity seawater element for use in high fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water.
FILMTEC SW30HR-380	The FILMTEC SW30HR-380 is a premium grade seawater reverse osmosis element featuring both high active area and high salt rejection to offer the best long-term economics for seawater desalination systems.
