These high rejection and high productivity seawater reverse osmosis membranes are specially designed for marine applications. AMI SWRO membranes are ideal for seawater desalination in shipboard applications, watermakers, land-based desalinators and sea-based desalinators.

AMI membrane elements are among the finest in the industry. With hundreds of thousands of membranes in operation world-wide, we offer these seawater RO membranes in standard commercial sizes. AMI Membranes are Made in the USA in our ISO 9001:2015 Certified Facilities. Each membrane meets or exceeds our strict performance requirements before shipping. For the past 30 years we have earned a reputation of delivering consistent, high quality which makes AMI SWRO Membranes the natural choice for use in seawater desalination, shipboard applications, watermakers, land-and-sea based desalinators.

Convert seawater into drinking water on yachts, boats, cruise ships, off-shore platforms, and resorts.
99.4% Stabilized Salt Rejection Reverse osmosis membranes remove up to 99% of total dissolved solids.
