Work Step by Step

This first separation is based upon differences in solubility, basically what compounds in the coffee are soluble within water. These compounds dissolve in the water, flavoring it. What is now left is the flavored water (coffee) and the coffee grounds, which are insoluble in water. These are separated through a filtration process. Specifically, the water flows through a coffee filter, bringing its flavor compounds with it. The much larger grounds are caught by the filter, making them easy to dispose of later.
