Abstract: Phenols is a common pollutant discharged by polymeric resin production chemical industries textile industries oil refineries coking plant etc It is considered as a bio refractory pollutant in wastewaters due to their high toxicity high oxygen demand and low biodegradability The efficiency of the biological treatment is often hampered by the presence of bio refractory pollutants though they are most economical and conventionally used treatment strategies On the other hand photocatalysis oxidizes almost all pollutants but considering the economical aspects the use of photocatalysis alone as treatment may not look lucrative Thus a hybrid method consisting of using photocatalysis to increase the biodegradability of the wastewaters up to a desired level followed by biological treatment is perhaps needed for the future to achieve an overall performance to meet the limits of the environmental legislation In this research the solar photocatalytic treatment was used as a pretreatment method to increase biodegradability prior to the biological treatment process The wastewater samples were collected from the phenolic wastewaters generating industries and characterized for various physio chemical parameters viz pH phenol concentration COD BOD chlorides and sulphates Studies were conducted with simulated wastewaters based on the concentration of the pollutants in the real wastewaters
