1) By boiling away the solvent. If the solute is a gas, boil away the solute, then dissolve it again in less solvent.

2) By forcing the solution through a membrane, which lets only the (presumably) smaller molecules of the solvent through.

3) By fractional crystallization. The solvent crystallizes pure, leaving the solute outside of the crystal lattice. This method was used in northern countries to concentrate sea water for salt recuperation.

4) By consuming the solvent with some chemical reaction, if any such can be found.

5) By precipitating the solute in some insoluble form, then, after filtration, dissolve it again in less solvent.

What else? Hand picking the molecules of the solvent out of the solution, will probably not be very effective . . .
