BW30-400/34 Typical Properties
Active Area | Feed Spacer | Permeate Flow Rate | Typical Stabilized | Minimum Salt | |
| FilmTec™ Element | (ft2) (m2) | Thickness (mil) | (GPD) (m3/d) | Salt Rejection (%) | Rejection (%) |
| BW30-400/34 | 400 37 | 34 | 10,500 40 | 99.5 | 99.0 |
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.

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.
