Examples of Filtration
Filtration is a separation method in which, as its name says, the separation of two substances that are in a solid state suspended within a liquid compound is carried out , this process requires that this liquid pass through a porous surface which acts as of filter and the solid ones are those that are retained in said filter, this happens because the pores are smaller than the solid particles so they prevent these substances from passing and finally separation occurs.
Filtration is a process that is used in many activities of daily life, it also has a very important use in the food and petrochemical industry or also in chemistry itself, an example is the purification of water to produce more drinking water for the population. Filtration processes can be divided into the following types:
- Straining: In this type, the process, the solid particles within the liquid can be seen with the naked eye without the need for any artifact, but a filter is used which is known as a strainer.
- Sieving: The solid particles are large in size inside a sieve, in this type the filtration occurs through the mixture of several solid elements.
- Filtration: This is the most typical and consists of the separation of solid particles that have a size smaller than 10 microns or also known as colloidal size.
Examples of filtration:
- The strainer used in the kitchen to separate rice from water or fruit juice from pulps.
- The network system in the sewers to prevent garbage from entering.
- The filter paper used to separate sand from water.
- The tea bags used to make hot drinks with the flavor of said leaves without them passing.
- The processes used to make wine.
- Filters inside vehicle engines to filter oil.
