Membrane Technology

Membrane technology is used for the efficient separation. Actually membrane is a thin film manufactured from polymers, metals and ceramics. Impurities are separated both from liquid and gases by using membrane technology.

Membrane:
Membrane is a barrier that allows passage of certain components but rejects others.
Types of Membrane:
Recently four types of pressure-driven membranes are used-

  1. Microfiltration (MF) membrane: The pore size of this type of membrane is 0.1 µm. It usually separates Particles, Sediments, Algae, Protozoa, Bacteria etc.
  2. Ultrafiltration (UF) membrane: The pore size of this type of membrane is 0.01 µm. It usually separates small colloids, viruses etc.
  3. Nanofiltration (NF) membrane: The pore size of this type of membrane is 0.001 µm. It usually separates dissolved organic matters, divalent ions (Ca2+, Mg2+) etc.
  4. Reverse-osmosis (RO) membrane: It’s a semipermeable membrane. It usually separates monovalent ions (Na+, Cl-)
