Ozonation has been proven by many past studies to be an effective treatment for removing color and improving other water- quality attributes for textile wastewaters. Recent research and development efforts have combined simple ozonation with ultraviolet irradiation to synergistically enhance wastewater treatment in the food-processing sector; similarly dramatic increases in treatment efficacy may be possible for textile wastewaters. Technical details are thus presented describing our advanced oxidation process of UV-enhanced ozonation and the mobile, pilot-scale prototype developed for on-site evaluations of this improved water-treatment method.
