Reverse Osmosis Membranes
Seawater & Brackish Water RO Membranes
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.
| Model | Size | Capacity (Nominal GPD) | Pressure Range | Manufacturer | Datasheet | Product |

AMPAC stocks RO membrane elements from several leading manufacturers, including Toray, Puroflo, and our own AMPAC-branded membranes, covering brackish water, seawater, and low-energy configurations. Carrying multiple brands lets us match the right element to each system's feed water chemistry, pressure availability, and rejection requirement rather than forcing a one-size-fits-all membrane onto every application.
Low-energy membrane elements are worth considering where feed pressure is limited or energy cost is a major operating factor -- they achieve target rejection rates at lower operating pressure than standard elements, at some tradeoff in flux. Brackish and seawater elements are built for their respective TDS ranges and are not interchangeable between applications.
Not sure which brand or configuration fits your system? Contact AMPAC with your current element's model number and system specifications, and we will confirm compatibility before you order.
