Reverse Osmosis System
In order to understand the process of Reverse Osmosis Sytem (ROS), one should first know what is meant by Osmosis.

Imagine a hypothetical experiment as shown in figure1.1. A container is divided into two compartments using semi-permeable membrane. Semi-permeable membrane has a property of selective passage for certain substances i.e. this membrane allows only water to pass through, while salt and other components are rejected by the membrane. The left-hand compartment is filled with pure

water. The right hand compartment is filled with a salt solution. Pure water has higher chemical potential (or energy) when compared with the salt solution. Second law of thermodynamics states that the flow is always from higher energy to lower energy. Hence, the water flows from left-hand compartment to right hand compartment. This phenomenon of transport of water across semi-permeable membrane from low salt concentration to high salt concentration is called Osmosis.
