Phenol and its derivatives are considered among the most hazardous organic pollutants from industrial wastewater and they are toxic even at low concentrations. Besides the existence of phenol in natural water source it can lead to the formation of other toxic substituted compounds. So this has led to growing concern on setting up of rigid limits on the acceptable level of phenol in the environment. The various methods for the treatment of phenol from wastewater streams are briefly reviewed. The various technologies like distillation, liquid-liquid extraction with different solvents, adsorption over activated carbons and polymeric and inorganic adsorbents, membrane pervaporation and membrane-solvent extraction, have been elucidated. The advantages and disadvantages of the various methods are illustrated and their performances are compared.
