What does the process of filtration accomplish?

The process of filtration is primarily designed to separate solid particles from a liquid or gas. This method utilizes a porous barrier, like filter paper or membranes, which allows the fluid to pass through while retaining the solid particles. For instance, in a mixture of sand and water, filtration will enable the water to flow through the filter while trapping the sand, effectively achieving separation.

This method is widely used in various applications, including water treatment, laboratory procedures, and industrial processes, where purity of the liquid is essential. The process does not involve any alteration of the chemical composition of the substances being filtered, nor does it generate a solution from solids, making it distinct from other separation techniques that might alter the state or composition of the materials involved.
