Explain different filtration techniques

Question

Accepted Answer

Filtration techniques are used to separate solids from liquids or gases by passing the mixture through a filter medium.

Gravity filtration: Uses gravity to pull the liquid through a filter medium, leaving the solid behind.
Vacuum filtration: Uses a vacuum to speed up the process of pulling the liquid through the filter medium.
Pressure filtration: Applies pressure to force the liquid through the filter medium, separating it from the solid.
Centrifugal filtration: Uses centrifugal force to separate the solid from the liquid by spinning the mixture at high speeds.
Membrane filtration: Utilizes a membrane to separate particles based on size, allowing smaller particles to pass through while retaining larger ones.
