FILMTEC BW30-400 / 34i-FR Durable High Productivity Fouling Resistant RO Element with iLECâ„¢ Interlocking Endcaps
Features
The FILMTEC™ BW30-400 / 34i-FR has optimized construction for durable, high rejection, high productivity performance in purifying water with high biological fouling tendency. With Dow’ s proprietary FR membrane technology that provides superior fouling resistance and cleanability, this product combines the best features of the FILMTEC BW30-365-FR and BW30-400-FR elements.
The BW30-400/ 34i-FR element 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.
High rejection FILMTEC RO membrane that has the widest pH cleaning range in the industry ( pH 1-13) that allows for effective cleaning of scale, organic compounds and biofilm.
Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.
iLECâ„¢ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that compromise system integrity and cause poor water quality.
This unique combination of features offers system operators the best long-term economics and most trouble-free operation currently available for RO membrane purification of fouling waters.
