MICRODYN High Rejection & Low Energy Brackish Water RO Membranes

Reverse osmosis (RO) membranes remove a large majority of contaminants from water, including even the smallest monovalent ions like silica and chloride, as well as micro-contaminants like pesticides and fertilizers. RO is capable of rejecting over 99% of dissolved salts (ions), particles, organics, and more from the feed water.  The MICRODYN RO elements are available in standard 4” and 8” spiral-wound designs to meet all of your new equipment and direct replacement needs.

High Rejection

High rejection MICRODYN RO elements are made with a tighter membrane, leading to higher salt rejection than the low energy alternative. Obtaining increased salt rejection requires a higher feed pressure, and these elements offer 99.5% rejection.* These MICRODYN RO elements are available in standard 4” and 8” spiral-wound designs with a high rejection BW RO membrane. In addition, MICRODYN RO includes a line of seawater membranes to handle all your desalination needs. It is simple to update your RO system with MICRODYN RO elements.

Fouling Resistant

Another option with MICRODYN RO membranes are fouling resistant (FR) designation. These elements are a great choice when membrane fouling is a concern. They offer 99.5% rejection, still a high rejection membrane, and are an excellent competitive product for industrial water streams and other fouling streams.

Low Energy

Pressurizing the feed water at an RO plant takes substantial energy. When very high purity water is not required, using low energy elements can provide significant energy savings at the plant. Low energy MICRODYN RO elements require lower feed pressure to operate while still offering considerable salt rejection expected in an RO element.


MICRODYN RO Membranes are ideal for water purification applications. The high rejection elements are perfect for applications requiring high purity or a very clean permeate stream, such as those found in the pharmaceutical and bio-technology industries.
