Abstract
In a method for making a nanofiltration membrane, an ultrafiltration membrane is disposed onto a support module. A plurality of interface polymerization reactants is applied to the ultrafiltration membrane. The interface polymerization reactants are reacted to form the nanofiltration membrane so that the nanofiltration membrane has a predetermined pore size. A nanofiltration membrane includes an ultrafiltration membrane. An interface polymerized nanofiltration membrane is deposited on the ultrafiltration membrane. The nanofiltration membrane has a predetermined pore size.
