What is Filtration…???

Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids(liquids or gases) by interposing a medium through which only the fluid can pass.

The fluid that passes through it is called Filtrate.

Different methods of filtration

Hot Filtration

Cold Filtration

Vaccum Filtration

Hot FiltrationThis method is commonly used to separate solids from a hot solution.

This is done in order to prevent crystal formation in the filter funnel and other apparatus that comes in contact with the solution.

Cold FiltrationThis method uses ice-bath in order to rapidly cool down the solution to be crystallized rather than leaving it out to cool it down slowly in the room temperature. This technique results to the formation of very small crystals as opposed to getting large crystals by adding the solution down at room temperature.

Vaccum FiltrationThis technique is most preferred for small batch of solution in order to quickly dry out small crystals.This method requires a bucher funnel,filter paper of smaller diameter than the funnel,Buchner flask and rubber tubing to connect to vaccum source.

More about FiltrationFiltration is another ancient and widely used technology that removes particles and at least some microbes from water. A variety of filter media and filtration processes are available for household or point-of-use treatment of water. The practicality, ease of use, availability, accessibility and affordability of these filtration media and methods vary widely and often depend on local factors. The effectiveness of these filtration methods in reducing microbes also varies widely, depending on the type of microbe and the type and quality of the filtration medium or system.
