RO Membrane Meets Demand for Higher Production Rates

July 10, 2015

In today’s marketplace, there is a growing demand for higher production rates from RO membranes. Many light commercial applications require high water output, which standard thin-film membranes have not been able to treat. Many tap water reverse osmosis membrane elements were initially designed to achieve specified flow and rejection rates under only 15% recovery, thus dispensing a lot of water to the drain.

It is possible to run the membranes in series to meet increased demands and increase the recovery rate, or to employ a concentrate recycle option on the system. This can, however, lower operational efficiencies of the system’s performance and increase the system cost. Not having proper pretreatment can also lead to premature scaling and fouling of the membranes, and subsequent decreased output and lifetime expectancy of the membranes. While there are several options for increasing the efficiencies and lowering the waste from reverse osmosis systems, many of these concerns can be addressed by starting with the membrane element.

To help light commercial and tap water applications increase operational efficiency, Axeon Water Technologies has introduced the TF-3012-500 reverse osmosis membrane. This membrane produces 500 gpd with a 98% salt rejection rate at only 70 psi. Utilizing Axeon’s proprietary HF5 Technology, the TF-3012-500 membrane increases efficiency and provides a 40% recovery rate while producing 25% less waste than standard membrane elements. Its high active membrane area and the unique multi-leaf design provide excellent system operation for the user. The membrane can also be retrofitted onto existing systems already in use in the field. The Axeon TF-3012-500 membrane is shipped 100% dry for convenient handling and to maintain the integrity of the element’s performance. Meet your customer’s higher production rate demands while sending less water to the drain with the Axeon TF-3012-500 RO membrane.
