Theory:

We use a filtration process to separate the impurities from the drinking water. Now, let's learn more about this process.
 
Principal:
Filtration is a purification method that can separate a mixture consisting of a liquid substance and the impurities in it.
Function:
Take the mixture of liquid and solid substance in the filter. The filter separates the solids from the liquid; therefore, the solid remains in the filter. Finally, we get the pure liquid in a separate vessel.

Application:
  
1. Filtration process is essential to separate the impurities from the drinking water.
 
2. In pharmaceutical process filtration is necessary to make new drugs.
