Residential Nanofiltration (NF) Membrane

Independently developed by VONTRON, the nanofiltration membrane works under extremely low pressures and is applicable to a variety of water purifying devices and mineralized water purifying machines. NF membranes is used for reducing a solution's ionic strength and removing hardness, organics, and particulate contaminants.
