T/T
E-MEM BW(Brackish Water)&FR(Fouling Resistant) membrane can separate salts from water and are produced with an advanced technology that ensures precision, consistency, and reliability. It is mainly used for industrial water such as pure water manufacture of various scales, boiler supply water, etc. It is also used for the treatment of high concentration saline wastewater and the reuse of brackish water.
Offering proven performance, Membrane Element BW-365/400、BW-365FR/400FR、BW-4040
1 With years of proven performance.
2 High performance and long element life.
3 BW type can offer the most effective cleaning performance durability.
4 BW type delivers high quality permeate water while minimizing unit cost.

1. 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 7.5, 15% recovery.
2. Flow rates for individual elements may vary but will be no more than 15% below the value shown.
3. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feed water characteristics and operating conditions.
4. Sales specifications may vary as design revisions take place.
5. Active area guaranteed ± 3%.
