Filtration vs. Sieving: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Updated on October 2, 2023
Filtration involves passing a liquid or gas through a filter to remove unwanted particles, while sieving separates particles based on size using a sieve.

Key Differences
Filtration is a method that separates particles from a fluid (liquid or gas) by passing it through a filter, a permeable material designed to trap unwanted particles. In contrast, sieving refers to the process wherein particles are separated based on their size, utilizing a sieve which has holes or apertures of a defined size, enabling the separation of finer particles from coarser ones.

The application of filtration often involves the separation of suspended particles from fluids, usually when the particles are relatively small in size, permitting the fluid to pass through while restricting the solid particles. Sieving, on the other hand, is applicable when the particles to be separated are larger and are typically used to separate solids from solids, categorizing them based on size through a mechanical shaker or by hand.

Filtration finds its significant applications in various industries like water treatment, chemical manufacturing, and in laboratories where the removal of minute particles from a fluid is imperative. Whereas sieving is prominently used in food industries, construction, and laboratories to segregate particles of different sizes, notably where the gradation of particle sizes is vital.

In filtration, the filter medium can range from a complex membrane to a simple cloth depending upon the application and the size of the particles to be removed. Sieving, however, commonly utilizes a sieve, a tool generally constituted of a mesh stretched in a frame, the construction of which is largely consistent across applications with variations mainly in the size of the apertures.

Filtration can be utilized to separate particles that are often invisible to the naked eye, considering it's capable of separating microscopic entities from a fluid. In contrast, sieving is employed for the separation of larger, often visible particles and is less effective for separating microscopic entities due to the limitation posed by the aperture sizes.
