Filtration Definition

Filtration is defined as the process in which solid particles in liquid or gases are separated by the filter that only allow the liquid to pass through it but blocks the passage of solid.

This process is carried out using a filter medium, for instance, filter paper. The pores of the filter medium are bigger as compared to the solvent particle but are smaller compared to the solute particle, so they allow only solvent particles to pass through them the solute particle is left on the other side making the solution free from the insoluble solute.

The principle of filtration is based on the difference in sizes between the particles.

Filtration is a method to separate the components of a mixture where the solvent part is liquid and the solute is an insoluble solid. Let’s know more about Filtration Definition, Process, Application and examples in detail below.

In simple words, Filtration is the process in which solid particles in liquid or gases are removed by the filter that allow the passes of liquid but blocks the passage of solid. The mechanism of “filtration” can be mechanical, biological, or physical.
