The alternative is the extraction of the organic components with a solvent out off the water followed by an evaporation of the solvent to get the product The evaporation heat of a solvent is mostly smaller than of water and the concentration of the product in the solvent is higher than it was in the water so that much less energy for the evaporation of the solvent is required than for the
