Abstract

The degradation of azo dye wastewater containing Acid Red 14 has been investigated. Significant drop in COD and concentration of dye has been observed. The effect of ozonation time on the COD removal and mineralization of azo dye was studied and the result was analysed in terms of COD removal efficiency. From the experimental results it has been observed that with increasing the ozonation time the degradation of dye increase. The ozone concentration of 55 mg/l at flow rate 5g/hr. reduced 75% COD and degrade 95% dye after 20 minutes of ozonation at the dye concentration was 1500mg/l. To reduce the cost of ozonation for maximum dye degradation, ozonation followed by anaerobic biodegradation was carried out.
