SpiroPure commercial RO membranes in size 2.5x21 are your best choice for your smaller commercial RO systems and other reverse osmosis needs. 2521 membrane elements such as the brackish water BW-2521 RO membrane and the XLE-2521 / XLP 2521 extremely low pressure membrane help provide high performance treatment of TDS. Try SW-2521 seawater desalination membranes for high rejection of sodium for treatment of sea water and other high salinity applications. When you need low pressure, low energy membranes with high RO performance, the brackish water and extreme low pressure elements provide two different options for lower pressure requirements, for lower energy consumption and more energy savings.
