General Information

TFBW-4040-100HR is manufactured as an equivalent, direct replacement, alternative, analog, retrofit and analogue for DuPont DOW Filmtec LC HR-4040 (LCHR 4040) RO membrane.
TFBW-4040-100HR reverse osmosis membrane elements are developed for brackish water treatment, ideal for reverse osmosis plant managers and operators dealing with brackish water with pre-treatment.
TFBW-4040-100HR reverse osmosis membrane element provides consistency, high permeate water quality, high performance and productivity, and long service life.

Features & Advantages

  • Provides high-quality permeate water
  • Stable salt rejection rate and high permeate flow rate
  • Optimized design, good resistance to fouling results in long service life
  • High chemical tolerance for cleaning with highly effective cleaning performance
  • Simple and economical element replacement

Applications

  • Industrial pure water
  • Industrial wastewater reuse
  • Slightly contaminated water

Specifications

  • Configuration: Spiral wound element
  • Membrane Polymer: Polyamide thin-film composite

    Standard test conditions:
    The above performance is initial(data record after 30 minutes of operation), based on the following conditions:
    2,000 ppm NaCl solution
    225 psi(15.5 bar) operating pressure
    25°C(77°F) operating temperature
    15% permeate recovery
    7.5-8 pH range
    *Permeate flow for individual elements may vary but will be no more than ±15%.
    **Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending on feed water characteristics and operating conditions.
