Table 5: Comparison of air pollution compounds measured at the end of the infectious waste combustion air vent (mg/m\({}^{3}\)). tively. It was found that, when compared with the U.S. EPA standards [32] for TSP, CO, NO\({}_{2}\), HCl, Hg, SO\({}_{2}\), HF, and percentage of opacity, the recommended safety thresholds were met or exceeded the expectations in reductions, with concentrations of 120 mg/m\({}^{3}\), 45.80 mg/m\({}^{3}\), 470 mg/m\({}^{3}\), 119 mg/m\({}^{3}\), 0.05 mg/m\({}^{3}\), 79 mg/m\({}^{3}\), 16.40 mg/m\({}^{3}\), and 10%, respectively. Efficiency Comparison of Wastewater with and without an O\({}_{3}\) System and the Standards of the U.S. EPA (1986)  
The effluent samples released from the infectious waste incinerator in this study were collected at a sample volume equal to 5 L. The appearance of the effluent was light yellow. Laboratory tests were carried out against the Notification of the Ministry of Industry for the industrial effluent standard. The results of the analysis of the wastewater quality from the incineration of infectious waste were not found to exceed the standard. Ozone has been widely used for a long time, and now it is mixed with water in the tank before being injected into flue gas in the wet scrubber room. A chiller was installed in order to control the temperature of the cold water in the wet scrubber room during treatment, as it was found to be most efficient in the process of ozone gas oxidation. Ozone is a strong gas phase oxidant that can achieve pre-oxidation at low temperatures of 15-20 \({}^{\circ}\)C, which was a significant factor for this investigation [7; 8]. This was followed by post-absorption to completely remove the oxidized products. Ozone has long been suggested as an alternative to improve air pollution and water quality [31].
