4x40 / 4040 Industrial RO Membrane Elements

SpiroPure industrial RO membranes in size 4x40 are your best choice for your commercial RO systems and other heavy duty reverse osmosis needs. 4040 membrane elements such as the brackish water BW-4040 RO membrane, the ultra low pressure ULP-4040 membrane, XLE-4040 / XLP 4040 extremely low pressure membrane, FLR-4040 / FR-4040 fouling resistant membrane, and more help provide high performance treatment of TDS. Try seawater desalination membranes for high rejection of sodium for treatment of sea water and other high salinity applications. Fouling resistant membranes have a wider spacer for less membrane fouling for outstanding wastewater and other heavy-duty applications. When you need low pressure, low energy membranes with high RO performance, the brackish water, ultra low pressure, and extreme low pressure elements provide three different options for incrementally lower pressure requirements, for lower energy consumption.
