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 is called the filtrate. Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. 2  Depending on the application, either one or both of the components may be isolated.
Filtration. This is a more common method of separating an insoluble solid from a liquid. An example of such a mixture is sand and water. Filtration is used in water treatment plants, where water from rivers are filtered to remove solid particles.CLICK HERE to see how it works. Evaporation Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent.The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue.ost of them can be separated, and the kind of separation method depends on the kind of mixture it is. Below are some common separation methods: Paper Chromatography. This method is often used in the food industry. It is used to identify chemicals (coloring agents) in foods or inks.
