FFM-ULP Series: Ultra Low Pressure Reverse Osmosis Membrane
FFM’s low-pressure RO membrane delivers 99.5% desalination efficiency at just 0.8-1.2 Mpa operating pressure—approximately two-thirds that of conventional membranes.
Ideal for municipal tap water, groundwater, and surface water with low-to-medium salinity, it significantly reduces equipment and operational costs. This membrane is widely deployed in water purification facilities and across food and beverage, dairy, electronics, pharmaceutical, and other light industrial sectors.
