Membrane technology - Wikipedia

Membrane separation processes have a very important role in the separation industry. Nevertheless, they were not considered technically important until the mid-1970s. Membrane separation processes differ based on separation mechanisms and size of the separated particles. The widely used membrane processes include microfiltration, ultrafiltration, nanofiltration, reverse osmosis, electrolysis, dialysis, electrodialysis, gas separation, vapor permeation, pervaporation, membrane distillation, and membrane

Pressure Drop and its Effect on Membranes - Synder Filtration

Pressure Drop and its Effect on Membranes Pressure drop is defined as the loss of pressure between the inlet and outlet of a membrane system, housing (pressure vessel), or element. When a pressure drop exceeds the normally reported value, it indicates that physical plugging or scaling of the membrane is taking place.
