Filtration is the act of separating one or more distinct phases from another in a process that uses physical differences in the phases (such as particle size or density or electric charge). In short, it is the action of separating solid from liquid. An easy example would be the filtration of coffee ground from water using filter paper.

However, there are different ways of filtration or separation for different distinct phases.
To separate Solid from Solid, Screening, Classification, Elutriation method applies.
To separate Solid from Liquid, filtration, Sedimentation, Flotation, Scrubbing, Electrostatic precipitation method applies.
