Question

Differentiate between the following: Reverse osmosis and Distillation

Answer 1

Reverse Osmosis	Distillation
Reverse osmosis which is also commonly referred to as RO is a type of filtration method used for the removal of molecules and ions from a certain solution.	Distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture.
Reverse osmosis involves the application of pressure (usually greater than the osmotic pressure) on one side of the solution where a semipermeable membrane is placed in between the solutions.	It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture.
This membrane is used to filter out contaminants down to the smallest particles. The contaminants are often referred to as RO concentrate.	The process of distillation exploits the difference in the boiling points of the components in the liquid mixture by forcing one of them into a gaseous state.
