This study investigates the successful removal of color from wastewater generated during the dyeing of widely used viscose fabrics in the textile industry using the advanced oxidation process, UV/ H2O2. Subsequently, the usability of these treated waters for repeated dyeing is examined. No chemicals other than the dye were added during the dyeing processes. The results demonstrate that viscose samples can be dyed successfully up to the 3rd cycle without any significant loss in color difference and fastness values. While no change in pH values was observed until the 7th cycle, there was a decrease in conductivity values, resulting in the samples being dyed in progressively lighter colors. No significant losses in fastness and strength were detected in the samples until the 7th cycle. The textile finishing industry is known for its high water consumption and pollution, contributing to a rapid decrease in accessible clean water resources. This wastewater is discharged into the environment, posing significant environmental challenges. According to the findings of this study, the ability to reuse the same water for up to 3 cycles can offer substantial advantages in terms of both the environment and cost savings.
