Low Energy Brackish Water

FILMTEC Low Energy Brackish Water Elements Drive Down System Operation Costs

FILMTEC™ low-energy / low-pressure products combine optimized membrane chemistry with automated precision fabrication to maximize system output to unprecedented performance. FILMTEC elements offer high performance over the operating lifetime without oxidative post-treatments used in many competitive products. This is one reason FILMTEC elements are more durable and clean more effectively over the widest pH range (1-12) 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 28 mil feed spacer 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 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. It also features 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 LE-400 element is a new low energy reverse osmosis element for customers with strict energy cost and unit price needs.
  • 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. Its high active area design coupled with the highly productive FILMTEC XLE membrane makes it the lowest pressure RO element - resulting in lower energy costs.

FILMTEC Low Energy / Low Pressure Elements


New! 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.

New! 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.

FILMTEC BW30LE-440

The high surface area of the FILMTEC BW30LE-440 element permits designs of new RO systems that meet productivity targets with fewer elements than standard 8-inch elements resulting in lower installed system cost by reducing the number of system components and lower installation expense.
