You can't. Milk contains a lot of water. so adding water is just diluting the milk. Besides "pure milk" is a very strange phrase since milk has many different components, and fresh milk isn't even homogeneous.
By distillation. Heat the solution to a temperature between the boiling point of water and the boiling point of alcohol. The one with the lower boiling point will boil first . Then it is passed throught a condenser to be collected in a receiving flask. This leaves behind the other liquid with the higher boiling point in the distillation flask.

Dissecting Milk
They are aqueous solutions of various compounds in water, so they consist of many separate pure substances. Many of these can be separated by simple physical means (filtering, evaporating, centrifuge).

Yes Centrifugation is the most common technique used to separate cream from milk (especially raw cow milk).
Milk and water can be separated by boiling it, using a distiller, or by reverse osmosis using a filter.
Milk is not pure. It is a mixture.
