Nanofiltration definition

Nanofiltration or "NF", “NF” means a pressure-driven membrane technology designed to remove multivalent ions (“softening”) and other constituents based on the pore size, which ranges from 1 – 10 nanometers. Nanofiltration membranes typically operate under a pressure range of 600 – 1100 psi.

  • Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.

  • Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
