High Rejection & Low Energy Brackish Water RO Elements


Reverse osmosis (RO) membranes remove a large majority of contaminants from water, including even the smallest monovalent ions. RO is capable of rejecting over 99% of dissolved salts (ions), particles, organics, and more from the feed water.  


The MICRODYN RO series of brackish water RO membranes is ideal for water purification applications. These elements feature our best membranes for directly replacing competitive RO products and offer very high solute rejection. MICRODYN RO elements are available globally and can be sourced from our plants in the United States, China, and Germany.

Direct replacements to seamlessly meet your RO needs:


MICRODYN RO elements are available in standard 4” and 8” spiral-wound designs with either a high rejection brackish water (BW) RO membrane or a low energy (LE) RO membrane to meet all of your new equipment and direct replacement needs. With permeate tubes sized to match standard designs and either 400 ft2 or 440 ft2 of membrane area available in the 8” design, MICRODYN RO elements make it easy to directly replace competitive RO elements. For detailed technical information, please see our technical data sheets.



MICRODYN RO elements are ideal for a variety of applications:


  • Boiler feedwater
  • Industrial process water
  • Water re-use
  • Polishing effluent from MBR or UF


For further information on MICRODYN RO products, please do not hesitate to contact our MICRODYN-NADIR representative or our technical service team. We look forward to helping you meet all of your membrane needs.
