Background: Several important designs have been applied to remove toxic and hazardous organic substances like phenol and phenol compounds from wastewater, but there is a need to seek an alternative design to effectively remove organic pollutants from water to less hazardous compounds and a costeffective system. Methods: A modified internal loop airlift reactor was designed to remove the organic pollutants in synthetic wastewater using an efficient and cost-effective treatment technique by means of a synergistic effect of combination oxidation, stripping, and adsorption. The influence of the current style was experimentally examined in the treatment of synthetic phenol contaminated wastewater. The practical device was tested under different airflow rates range (2-15 L/min) through gross difference retention period (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 the maximum removal efficiency (89%) of phenol from the synthetic wastewater. Conclusion: Successful removal of phenol from water by the removal efficiency of 89% boosts the success 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 environmental problems via treating wastewater before recycling and releasing it into natural water sources.

In this work, a modified internal loop airlift reactor has been designed to remove the organic pollutants in synthetic wastewater at an efficient and inexpensive treatment technique by means of a synergistic effect combining of (oxidation, stripping and adsorption). The validation of the current style was experimentally examined in the treatment of synthetic Wastewater contained chloroform. The experimental testing rig was implemented at various air flow rates range (5-20) (L/min), with total variable residence period (5-60 min) with a different molar ratio of CHCl3 to H2O2 i.e. 1:10, 1:15 and 1:20. The results showed that the best molar ratio of chloroform to hydrogen peroxide was 1:20 for the air flow rate 18 L/min and extended retention period (60 min) having the uppermost results (83.3%) to remove chloroform from the contaminated effluent water. This design complements the research objectives with high efficiency through the synergy of stripping, oxidation and adsorption processes to remove contaminated chloroform from wastewater. This work contributes to a part of the solution of the environmental problems of the contaminated water before recycling, reuse or released to our safe environment.
