The presence of phenolic compounds, such as phenol (carbolic acid or phenylic acid) and 2,4-DCP (2,4-dichlorophenol), in trace amounts in the agricultural environment and in chemical industries wastewater has been considered a potentially large risk for the environment and human health. Therefore, it is very important to develop effective techniques for removing phenolic compounds in wastewater. This research was conducted specifically to observe the effect of temperature of ozone production in the ozonation process to remove phenol and 2,4-DCP in the agricultural aquatic environment and industrial wastewater. This experimental study was conducted using a semi-continuous multi-injection bubble column reactor with initial concentrations of phenol and 2,4-DCP 50 ppm for 60 minutes ozonation. The effect of parameters namely, waste water flow rate, air flow rate, pH of the solution, and temperature were evaluated and optimized. Degradation efficiency, COD concentration, hydroxyl radical concentration were also monitored. It was found that the degradation efficiency at room temperature and low temperature (cold conditions) of phenol were 98.79% and 98.22%, respectively, while 2,4-DCP degradation at room and cold temperatures was 99.83% and 99, 99%, respectively.
