Reliable RO Membrane Elements for High-Efficiency Water Purification
AMPAC Water Systems offers a full range of premium-quality reverse osmosis membranes tailored for demanding seawater and brackish water treatment applications. Designed for high recovery, energy efficiency, and long operational life, our membranes are ideal for both commercial and industrial use.
From high-pressure seawater desalination to brackish groundwater filtration, our membrane elements are compatible with leading RO systems and meet stringent international performance standards.


Seawater RO Membranes
Seawater RO membranes are built for high salinity environments such as marine, offshore, and coastal water applications. These membranes are engineered to operate at elevated pressures while delivering maximum salt rejection.
Key Features
Brackish RO Membranes
Brackish water membranes are ideal for treating water with medium salinity—typically from groundwater, municipal sources, and inland wells. These membranes provide high flow rates and reliable contaminant rejection with lower energy consumption.
