Abstract

Textile wastewater represents one of the world's largest aquatic pollutants due to industrial activities. Ozonation, an advanced oxidation process (AOP), serves as a cost-effective wastewater treatment method. This study compares emission spectra from series and parallel-configured dielectric barrier discharge (DBD) reactors and correlates them with ozone production for textile wastewater treatment. The discharge emission spectrum (OES) was analyzed to identify reactive species, while ozone concentration was quantified via titration. Ozonation was applied for 0ā€“60 minutes, monitoring absorbance, dissolved oxygen (DO), total dissolved solids (TDS), total suspended solids (TSS), and conductivity. OES analysis revealed higher emission intensities of OH radicals and Nā‚‚ in the series configuration versus parallel, indicating enhanced plasma reactivity. Consequently, the series configuration yielded superior ozone production, achieving 53.14% degradation efficiency after 60 minutes. Significant reductions in absorbance, TDS, TSS, and conductivity occurred alongside increased DO. Longer treatment durations improved degradation efficiency.
