Commercial RO Membrane Replacement
SpiroPure commercial RO membrane elements are great for a variety of commercial RO systems and reverse osmosis applications. Brackish water membranes produce high quality water for brackish and tap water applications with low pressure, high permeate flow. For very low pressure and low energy consumption, we offer extremely low pressure reverse osmosis membrane elements for ultra energy savings! Our seawater desalination elements are perfect for treating sea water and other high sodium applications, with a high NaCl rejection rate. Our commercial membranes are offered in 2521 ( 2.5x21), 2540 (2.5x40), and 4021 (4x21) sizes.
