FilmTec™ BW30-400/34i Elements are ideal for reverse osmosis plant managers and operators dealing with challenging waters and wastewaters and looking for consistent, high performance, long element life and increased productivity.
FilmTec™ Brackish Water Reverse Osmosis 8" Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in large-scale industrial and municipal water treatment systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. Our RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet today's challenges for higher rejection using less energy and resisting foulants in challenging waters.
Uses
- Industrial water demineralization
- Production of municipal drinking water
- Water reuse
Advantages- Proven performance
- Delivers high quality permeate water while minimizing CAPEX
- Offers the most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1 – 13) tolerance and the support of DuPont technical representatives
- Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality
Typical Properties
- Permeate Flow Rate: 9,500 GPD (36 m3/d)
- Typical Stabilized Salt Rejection (%): 99.5
- Minimum Salt Rejection (%): 99.0

a. Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
b. Refer to Cleaning Guidelines in specification sheet 609-23010.
c. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure.
