Question

How can a suspension be separated?

Answer 1

Given that a Suspension is needed to be separated we can easily separate a suspension by method of filtration. Typically over . The bigger particles of a suspension usually settle or separate out of a mixture upon standing or are able to be filtered out, although not through filter paper.

Complete answer:
We all know that a suspension can be defined as a heterogeneous mixture in which the solid molecules are mostly visible and deposit at the bottom of the solution. This happens either when the solution becomes saturated by having more solute than solvent, or when the particles are just big enough to dissolve in the solution.
A suspension is a mixture of solid particles in a liquid. They remain suspended because of their small size and the attractive forces of the liquid molecules.Separation can only be done if the particle sizes are increased to a size where they will precipitate from the solution. Increasing the gravitational gradient with a centrifuge is also a way to effect the separation.
Usually, a combination of both is used. For many biological samples in a lab, the centrifuge may be sufficient directly. For industrial process centrifugation is not possible, and coalescence is the only practical method. This can be affected or enhanced with chemicals called "flocculants".
The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable. They can be separated from the mixture by the process of filtration.

Note: Important things to remember are that all suspensions are heterogeneous mixtures by nature.Similarly some of the material in a suspension will settle out on standing and not colloidal..
For the removal of Solid material in a suspension we can easily separate it using filtration process
