Nanofiltration is the recent advancement in the membrane filtration process for surface water filtration and fresh groundwater filtration process. This type of filtration helps in water softening and removal of disinfection from water. This type of membrane filtration method employs nanometer-sized cylindrical through-pores that pass through the membrane at 90°. The pore-size ranges from 1 to 10 nanometers. These nanofiltration membranes are made from polymer-based thin films. The most commonly used polymeric material is polyethylene terephthalate.
