BW30-400/34i

Summary

Product identification

The FilmTec™BW30XFR-400/34i Element is a spiral-wound element featuring a polyamide thin-film composite membrane. It is designed for reverse osmosis plant managers and operators dealing with challenging waters and wastewaters, aiming for consistent high performance, long element life, increased productivity, higher water quality, and outstanding fouling resistance.

Key features include:

• Delivers high quality permeate water while minimizing CAPEX and OPEX
• Offers the most effective cleaning performance, robustness, and durability due to its widest cleaning pH range (1 – 13) and chemical tolerance
• Includes iLEC™interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality

Typical Properties

• Active Area: 400 ft² (37 m²) (guaranteed ± 3%)
• Feed Spacer: 34-LDP
• Permeate Flow Rate: 11,500 GPD (43.5 m³/d)
• Typical Stabilized Salt Rejection: 99.65%
• Minimum Salt Rejection: 99.4%

Note: Permeate flow and salt (NaCl) rejection are based on standard test conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, 15% recovery. Flow rates for individual elements may vary by no more than ± 15%. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use.

Important Information

• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
• This product may be subject to drinking water application restrictions in some countries; please check the application status before use and sale.
