Summary
Product identification
The FilmTec™ BW30XFRLE-400/34 Element is a spiral-wound element with a polyamide thin-film composite membrane, designed for reverse osmosis plant managers and operators dealing with challenging waters and wastewaters. It offers an advanced membrane treatment with good water purity, improved fouling resistance, and low energy consumption.
Key features include:
- Good salt rejection with 30% lower pressures.
- Excellent silica, nitrate, and ammonium rejection.
- Effective cleaning performance, robustness, and durability due to its widest cleaning pH range (1-13) and chemical tolerance.
Typical Properties
- FilmTec™ Element: BW30XFRLE-400/34
- Active Area: 400 ft² (37 m²)
- Feed Spacer: 34-LDP
- Permeate Flow Rate: 11,500 GPD (43.5 m³/d)
- Typical Stabilized Salt Rejection: 99.3%
- Minimum Salt Rejection: 99.1%
Standard Test Conditions (for permeate flow and salt rejection):
- 2,000 ppm NaCl
