BW30HR-440i

Summary

Product identification

The FilmTec™ BW30HR-440i Element is a spiral-wound element with a polyamide thin-film composite membrane. It is designed for reverse osmosis plant managers and operators who manage controlled pre-treatment waters and seek consistency, high performance, long element life, increased productivity, higher water quality, outstanding fouling resistance, and reduced footprint installations.

Key features include:

• Delivers high quality permeate water while minimizing CAPEX and OPEX.
• Offers increased active area with highly 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.

Product water

• Permeate Flow Rate: 12,650 GPD (48 m³/d)
• Typical Stabilized Salt Rejection: 99.7%
• Minimum Salt Rejection: 99.4%

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, depending on feedwater characteristics and operating conditions.

Mechanical / hydraulic

• Active Area: 440 ft² (41 m²) (guaranteed ± 3%)
• Feed Spacer Thickness: 28 mil

Dimensions

• Element Diameter (C): 7.9 inches (201 mm)
• Individual Element Length (B) with iLEC™ end caps: 40.5 inches (1,029 mm)
• Net Length (A) of connected elements: 40.0 inches (1,016 mm)
• Internal Diameter (D): 1.125 ID (29 ID)

The element is designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 600 psig (41 bar)
• Maximum Element Pressure Drop: 15 psig (1.0 bar)
• pH Range (Continuous Operation): 2 – 11
• pH Range (Short-Term Cleaning, 30 min.): 1 – 13

Feed water

• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm

Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure; this type of oxidation damage is not covered under warranty. It is recommended to remove residual free chlorine by pretreatment prior to membrane exposure.

Additional Information

The use of this product 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.
