چکیده مقاله:
Background: Several important designs have been applied to remove toxic and hazardous organicsubstances like phenol and phenol compounds from wastewater, but there is a need to seek an alternativedesign to effectively remove organic pollutants from water to less hazardous compounds and a costeffectivesystem.Methods: A modified internal loop airlift reactor was designed to remove the organic pollutants insynthetic wastewater using an efficient and cost-effective treatment technique by means of a synergisticeffect of combination oxidation, stripping, and adsorption. The influence of the current style wasexperimentally examined in the treatment of synthetic phenol contaminated wastewater. The practicaldevice was tested under different airflow rates range (2-15 L/min) through gross difference retentionperiod (5-60 minutes) at a various molar ratio of phenol to hydrogen peroxide ranging from 1:10 to 1:20.Results: It was revealed that the preferred molar ratio of phenol to hydrogen peroxide equals to 1:20.Moreover, the airflow rate is 15 L/min with longer retention period of 60 minutes, indicating themaximum removal efficiency (89%) of phenol from the synthetic wastewater.Conclusion: Successful removal of phenol from water by the removal efficiency of 89% boosts thesuccess of the executed design as well as the scenario of conducting the synergistic processes (stripping,oxidation and adsorption) in one device and also increases the chances of solving environmentalproblems via treating wastewater before recycling and releasing it into natural water sources.
