SpiroPure commercial reverse osmosis (RO) membrane elements are used in different types of systems, like restaurants, hotels, and office buildings. Brackish water membranes produce high-quality water for brackish and tap water applications with low pressure, providing high permeate flow. For very low pressure and low energy consumption, we offer extremely low-pressure RO membrane elements for ultra energy savings! Our sea water membranes are perfect for treating seawater and other high-sodium applications, with a high NaCl rejection rate. Our commercial membranes are offered in 2.5" x 21" (2521), 2.5” x 40” (2540), and 4” x 21” (4021) sizes.
