WebNanofiltration (NF) Using pressure-driven separation for high rejection of multivalent ions. Highly efficient, low-energy pressure-driven separation Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by … See more The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration … See more • Packaging: The permeability of the package (materials, seals, closures, etc.) needs to be matched with the sensitivity of the package … See more The permeation of films and membranes can be measured with any gas or liquid.
