Treatment of wastewater containing rhodamine by advanced oxidation process (aop): fenton, photo-fenton and ozonation

The necessity for the conservation of natural resources and possible risks to human health have motivated efforts to minimize contamination problems. The agate dyeing and washing operations demand the utilization of considerable volumes of water and yield colored wastewater in addition to the possibility of high toxicity. The Advanced Oxidation Process (AOP) has been extensively evaluated, mainly due to its high capacity for degrading a large number of resistant substances with relatively low-cost procedures and simple operations. These processes are based upon the formation of the hydroxyl radical (OH•); which has a wide potential for oxidation. All three treatments yielded excellent results in color degradation.
