Colloids are more thermodinamically unstables systems than solutions.
The methods that can be used to separate colloidal systems can be:
Physical methods:
-Sedimentation (in the case of some suspensions)
-Centrifugation (suspensions and some sols)
-Drying (some gels)
Chemical methods:
-Precipitation (some sols)
-Adding a substance that change balance of electrical charge in the interfase of the componenets of colloid (sols, suspensions, aerosols, emulsions, foamings)
That is what I can remember about colloidal systems.
Good luck!

freeze it. it's why you don't freeze milk - it separates out...
