Ultra Low Pressure

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 ULP

ULP membranes operate efficiently at lower pressure, reducing energy consumption while maintaining excellent salt rejection. They are ideal for brackish water sources with moderate salinity and applications where operating cost is a key concern.

Their long service life and stable performance make them highly reliable for industrial and commercial water treatment systems.

  • 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%
