BW30XFR-400/34 Product Data Sheet

BW30XFR-400/34 Element

Description

Ideal for: reverse osmosis plant managers and operators dealing with

challenging waters and wastewaters and seeking consistent high

performance, long element life, increased productivity and higher water quality coupled with excellent fouling resistance.

With proven performance, BW30XFR-400/34:

Delivers the highest 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, and the support of DOW representatives

Permeate flow and salt (NaCl) rejection based on the following 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 but will be no more than ± 15%.

Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.

Sales specifications may vary as design revisions take place.

Active area guaranteed ± 3%. Active area as stated by DOW Water Solutions is not comparable to nominal membrane area often stated by some manufacturers.

Refer to Cleaning Guidelines (Form No. 45-D01696-en).

Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, DOW Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure. Please refer to Dechlorinating Feedwater (Form No. 45-D01569-en) for more information.
