The researchers investigated using Wet Air Oxidation to treat wastewater from textile industries. By increasing the temperature during the treatment process, they found that more organic pollutants were removed, improving the water quality. Higher temperatures led to better removal of Total Organic Carbon, Chemical Oxygen Demand, and turbidity from the wastewater. However, some organic compounds were not completely destroyed, indicating the presence of stubborn pollutants that resist oxidation. Overall, the study showed that Wet Air Oxidation can effectively treat textile wastewater by breaking down pollutants and improving biodegradability.
