Water pollution is a serious problem affecting the quality of life and environment. Wastewater treatment is necessary for solving this problem. A bubble column or bubble gas reactor is one of the most widely used in the chemical industries. Volatile organic compounds can be absorbed via gas bubbles in the column. Furthermore, the advantage of the bubble column is highly mass transfer and heat transfer rates. The performance of bubble column depends on bubble size, flow regime, gas hold-up and operating conditions i.e., pressure and temperature. This research focused on hot air bubbles to remove volatile solvents in the solution. CFD simulation was used to study the temperature distribution of gas bubbles within the bubble column. The experiments were carried out to reduce the volatile solvents in contaminated solution using hot air bubbles. The simulation results can be used to predict the performance of the bubble column and the optimal operating conditions for laboratory or industrial scale.
