FILMTEC Membranes Continue to Provide Consistent, Reliable Performance in Industrial Water Production from Brackish Sources

FILMTEC Brackish Water Elements Offer Alternate Strategies to Lower Your Cost to Produce Water

Whether you seek the latest innovative solution or the most cost effective one, our brackish water product line offers the right balance of quality, performance, reliability, and cost. With new products, technologies, and strategies for lowering the cost of water, FilmTec can maximize your system output to unprecedented performance. This is one reason FILMTEC™ elements are more durable and clean more effectively over the widest pH range (1-13) than other reverse osmosis (RO) elements.

Our low energy elements enable operational cost savings through lower energy usage and higher system productivity than other elements.

Automated precision fabrication with a minimum 28 mil feedspacer reduces the effect of overall fouling, maximizes element efficiency, and lowers your operating costs.

Higher surface area elements permit RO system designs that meet productivity targets with fewer elements. These new designs result in lower installed system cost by reducing the number of components and installation expense.

Introducing the Latest Additions to the FILMTEC Product Line

  • The new FILMTEC LE-440i element has the highest active membrane area (4223KB PDF) (440 ft2) in the industry and delivers operational cost savings by working at a lower pressure than competitive products.
  • FILMTEC LE-400 is a new low energy reverse osmosis element for customers with strict energy cost and unit price needs.
  • The new FILMTEC BW30-440i combines the highest solute (4223KB PDF) rejection and active membrane area (4223KB PDF) area in one product.
  • The new FILMTEC BW30-400/34i element offers a unique combination of high active area (4223KB PDF) (400 ft2), high solute rejection and a wide 34 mil spacer, enabling trouble-free operation and low operating costs on challenging feed streams.
  • All of the new elements, excluding the FILMTEC LE-400 element, also feature 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.
