Separation and purification

Separation and purification - Filtration, Screening, Sieving: In filtration, a porous material is used to separate particles of different sizes. If the pore sizes are highly uniform, separation can be fairly sensitive to the size of the particles, but the method is most commonly used to effect gross separations, as of liquids from suspended crystals or other solids.

Exploring Filtration: Types, Uses, & Industry Applications

There are several different types of filtration methods, each suited for specific applications. Let's explore some of the most common types: 1. Gravity Filtration. Gravity filtration is the simplest and most commonly used method of filtration. It relies on the force of gravity to pull the liquid or gas through a filter medium.
