Industrial Water

Highest Rejection and Proven Reliability for Industrial Water

Whether you seek the latest innovative solutions or the most cost effective one, our product line offers the right balance of quality, performance, reliability, and cost. And with new products, technologies, and strategies for lowering the cost of water, FilmTec can maximize your system output to unprecedented performance.

When highest rejection is paramount for demineralization in industrial and chemical processing water treatment, FILMTEC™ brackish water membranes effectively remove silica, dissolved solids, and total organic carbon (TOC) for reduced chemical regeneration usage, waste handling, and maintenance costs. FILMTEC brackish water elements are recommended for the treatment of water with salt concentrations between 50 and 10,000 mg/L.

FILMTEC BW30-400 The FILMTEC BW30-400 is the product of choice when the highest quality permeate is required.
FILMTEC BW30-365 For years, the FILMTEC BW30-365 has been the element of choice for system designers, OEMs and system operators requiring consistently high performance and maximum element life when treating difficult feed waters. This element offers proven performance, high rejection and outstanding robustness and durability across a wide range of feed conditions where unit price is a key driver.

Low Energy 8-Inch Elements
FILMTEC LE-440i The FILMTEC LE-440i element is a low-energy element featuring the highest active membrane area in the industry. It enables high productivity and low energy operation, while maintaining high-rejection performance, minimizing operating expense and lowering the total cost of water for industrial and municipal applications.
FILMTEC LE-400 The FILMTEC LE-400 element is a low-energy element for industrial and municipal applications that operates at low pressure to deliver energy savings in new equipment or replacement situations where energy cost is an important factor and unit price is a key driver.
FILMTEC XLE-440 The FILMTEC XLE-440 is an extra low energy, high productivity brackish water reverse osmosis element designed to deliver high quality water at low operating costs for municipal and industrial water applications.

Fouling Resistant 8-Inch Elements
FILMTEC BW30-400/34i-FR

The ultimate element for durable, high integrity, high productivity performance to purify water with high biological or organic fouling tendency. Offers the best long-term economics and most trouble-free operation for systems with variable pretreatment. Features:

  • A wide 34 mil feed spacer to lessen the impact of fouling and enhance cleaning effectiveness.
  • 400 square feet active area for more productivity without increasing the operating flux.
  • iLEC™ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that compromise system integrity and cause poor water quality.
FILMTEC BW30-400-FR Designed to purify water with high biological or organic fouling potential in systems with well-controlled pretreatment, FILMTEC BW30-400-FR reverse osmosis elements incorporate Dow's proprietary FR membrane technology that provides superior fouling resistance and cleanability. Features high active area (400 square feet) for more productivity without increasing the operating flux.
FILMTEC BW30-365-FR FILMTEC BW30-365-FR elements have purified high biofouling feed waters since 1997. Numerous customers around the world have experienced lower operating costs by using FILMTEC fouling resistant elements due to their superior fouling resistance and cleanability. Features a wide 34 mil feed spacer to lessen the impact of fouling and enhance cleaning effectiveness.
