A process for removing and concentrating acidic organic material from a water stream. The water stream is dispersed within an organic liquid solvent for removing substantial amounts of acidic organic material, such as phenol, mercaptans and thiophenols etc., from the water. The enriched organic solvent phase is separated from the purified water stream phase. Next, the enriched solvent is intimately contacted with substantially stoichiometric amounts of an immiscible concentrated caustic solution forming a three phase mixture in a second dispersion. This three phase liquid mixture is separated into a regenerated solvent phase, a second liquid phase of the alkali-metal salts of extracted acidic organic material, and a third phase of excess caustic solution. Preferably, both phase separations are undertaken in the presence of an electric field.
