Standard Brackish Water Membranes
Brief Introduction
The ZEKINDO BWRO Membrane Series delivers years of proven performance, combining high efficiency with long service life. It offers exceptional cleaning durability and consistently produces high-quality permeate water while minimizing overall unit costs.
Highlights of the BWRO Series
- High salt rejection for brackish water applications
- Optimized performance at low operating pressures for energy efficiency
- Available in standard and fouling-resistant (FR) variants to match different feedwater conditions
BW
Standard BW membranes are designed for typical brackish water applications with moderate salinity and relatively stable feedwater quality. They offer a balance of high salt rejection, reliable performance, and cost efficiency without requiring special surface treatments.
These membranes are ideal when feedwater is well-pretreated and not prone to significant fouling or scaling, making them a dependable choice for industrial, commercial, and municipal systems where conditions are predictable and consistent.

|---|---|---|---|---|---|---|---|
| 1 | ZEKINDO BW-4040 | 2400 | 9,1 | 99,65 | 255 | 1,55 | 2000 ppm NaCl |
| 2 | ZEKINDO BW-365 | 9500 | 36,1 | 99,65 | 255 | 1,55 | 2000 ppm NaCl |
| 3 | ZEKINDO BW-400 | 10500 | 39,7 | 99,7 | 255 | 1,55 | 2000 ppm NaCl |
- Permeate flow and salt (NaCl) rejection are based on the following standard test conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77 °F (25 °C), pH 7.5, and 15% recovery
- Flow rates for individual elements may vary, but will not be more than 15% below the specified value
- Stabilized salt rejection is typically achieved within 24–48 hours of continuous operation, depending on feedwater characteristics and operating conditions
- Sales specifications may change as design revisions are implemented
- Active membrane area is guaranteed within ±3%
