//HRLE – High Rejection & Low Energy BWRO Membranes

BW Series – Industrial Brackish Water RO Membranes

HRLE – High Rejection & Low Energy BWRO Membranes

IonClear™ HRLE series RO membranes change the surface characteristics through increasing the density of the sheet compared with traditional brackish water membrane elements. The membrane elements have stable rejection rate and the operating pressure is reduced by 33%. The application of this model enables the entire reverse osmosis system to provide the same permeate quality while reducing energy consumption by 1/3, thus improve the system’s operating economy. In addition, the number of membrane elements used in the system is reduced to save the construction cost of system.

  • High flux and high rejection rate

  • Reduce operating energy consumption while ensuring the permeate quality

  • Suitable for wider PH range to achieve good cleaning and recovery performance

Notes
  • Permeate flow for individual elements may vary ±15 percent from the value specified.
  • Active membrane area guaranteed ±4%.
  • Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
