The best way to separate a solid substance that has dissolved in water is to boil the water away, leaving the substance behind in the beaker. This method works because it allows the water to evaporate, leaving any dissolved solids (if they are not volatile) behind. Passing the solution through a filter is inappropriate since filtration is used for separating insoluble solids from liquids, not dissolved substances.
