INTEGRATED OZONATION PROCESS FOR TREATMENT OF REFRACTORY ORGANIC POLLUTANT- RB5

Textile and dyeing industries are one of the leading industrial sectors for producing colored wastewater. The effluents produced from these industries are problematic to treat because of their recalcitrant nature. Conventional treatment techniques are not suitable to treat this effluent due to presence of high amount of non-biodegradable compounds. Advanced Oxidation Process is gaining importance as an alternative to treat recalcitrant organic compounds as they are highly effective and environmental friendly. The foremost aim of present study is to analyze the performance efficiency of integrated ozonation process, i.e. ozonation combined with UV and Persulfate process to mineralize synthetic wastewater containing Reactive Black5 (RB5)as refractory pollutant. The effectiveness of process was analyzed on the basis of Total Organic Carbon and also effects of various operating parameters were also analyzed.
