Reverse Osmosis Technology, its Applications and Nano-Enabled Membrane

Reverse Osmosis (RO) is a method of obtaining pure water from water containing a salt, as in desalination [1]. It is a water purification technology that uses a semi permeable membrane to remove ions, molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.
