Can you separate salt from water using filtration?

yes

13.

Sodium chloride can be separated from rock salt by first adding water to the mixture to dissolve the sodium chloride. The separation then takes place in two stages:

evaporation followed by filtration

distillation followed by decanting

filtration followed by evaporation

filtration followed by decanting
