FFM-ELP Series: Extra Low Pressure Reverse Osmosis Membrane
FFM’s extremely low pressure reverse osmosis (RO) membrane is one of the membrane elements with the lowest operating pressure among existing reverse osmosis products, with a conventional operating pressure of only 0.5-1.2 MPa.
This series of membranes is mainly suitable for municipal tap water, groundwater, and surface water with salt concentrations within 1000 ppm, and is widely used in the preparation of purified water. It has lower operating pressure and reduced energy consumption, which can significantly improve operational economic efficiency.
