FFM-HR Series: High Rejection Brackish Water Reverse Osmosis Membrane
FFM’s high-rejection RO membrane series is engineered specifically for brackish and saline water desalination, offering low operating pressure, exceptional salt rejection (>99.6%), strong fouling resistance, and stable performance.
Ideal for waters with salinity below 5,000 ppm—including well and surface water—these membranes serve drinking water systems, ion exchange pre-treatment, and industrial applications such as power plant boiler feedwater, high-salinity wastewater treatment, and beverage production.
