Fouling Resistant

FILMTEC Membranes Reduce Membrane Fouling and Increase Efficiency for High-Fouling Potential Water Sources

High fouling feed waters need not result in frequent membrane cleaning and replacement. FILMTEC™ BW30-400/34i-FR, FILMTEC BW30-365-FR and BW30-400-FR elements reduce operating costs in most fouling-prone systems by lowering cleaning costs, reducing average system operating pressure, and extending membrane life. FILMTEC fouling-resistant (FR) elements feature proprietary FR membrane technology providing superior fouling resistance and cleanability in both potable and non-potable applications.

Automated precision fabrication, using FilmTec's robust fouling resistant membrane and the widest feed spacer in the industry, reduces the effect of overall fouling through optimal leaf-length construction which gives more uniform operating flux. FILMTEC membrane offers high performance over the operating lifetime of the element without oxidative post-treatments used in many competitive products. This is the reason FILMTEC membranes have the widest pH cleaning range in the industry (pH 1-13), enabling the effective cleaning of scale, organic compounds and biofilm. Combining the industry’s most robust membrane with the most advanced fabrication and FR technology, results in fouling resistant elements with the best long-term economics and unprecedented performance.

FILMTEC Fouling Resistant 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 BW30-365-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.
