Equivalent, equivalence, replacement, alternative, analog, retrofit, analogue, derivative, substitution: DuPont DOW FilmTec BW30HRLE-440i, BW30HRLE440i

General Information

TFBWLE-8040-440i is manufactured as an equivalent, replacement, alternative, retrofit, analogue to DuPont DOW FilmTec BW30HRLE-440i (BW30HRLE440i) RO membrane.
BW30HRLE-440i equivalent reverse osmosis membrane elements TFBWLE-8040-440i are developed for brackish water treatment, ideal for reverse osmosis plant managers and operators dealing with brackish water with pre-treatment.
This 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
  • Economical equivalent element for direct replacement of DuPont DOW FilmTec BW30HRLE-440i

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
150 psi (10.3 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.
