What is Membrane Filtration ?
Membrane filtration is the separation of components of a fluid by polymeric or inorganic membranes. The type of components removed depends on the pore size and the chemical characteristics of the membrane. Membrane filtration can operate in a range of modes: Cross flow or normal flow Pressurised or suction mode Outside-in or Inside-out mode 
|  | | Filtration Spectrum |
Microfiltration Ultrafiltration | Reject particles (including bacteria, parasites and Giardia cysts) based on pore size. Range from 2 - 0.003 µm. | Nanofiltration Reverse Osmosis | Separate out small molecular weight particles and ions in range 1-60 Å (0.0001-0.006µm ) on size and chemical properties |
