Which method would you use to separate silt from water filtration gas chromatography electrolysis distillation

The answer is "filtration"

Filtration is used to seprate a solid from a liquid in which it is suspended. Filtration is also used to separate a substance from a mixture because one is insoluble in the solvent and the other is solube. The separation is due to particle size.

I hope this helps.
