Abstract:
Wastewater treatment is essential to avoid water pollution of the receiving bodies. Conventional methods have failed to meet the standards. Humans are searching for better technologies i.e. Advance Oxidation Processes and the verification of these methods is an ongoing practice. In the current study five treatment methods, namely ozone (O3), ultra violet (UV), UV + FeSO4, UV+ O3, and O3+ UV were applied. Water quality before and after treatment was determined by testing color, odor, temperature, turbidity, electric conductivity, total dissolved solids (TDS), pH and chemical oxygen demand etc. After the treatment, sludge weight per liter of wastewater was also calculated on adding polymer. The best treatment method was UV+FeSO4 with COD removal efficiency of 82.14%, 87.50% and 98.03% in rubber industry, textile bleaching and textile dye-bath wastewater samples respectively. Whereas O3 treatment was the best for maximum turbidity removal (69.53%) in rubber industry. However, O3+ UV was the best for turbidity removal (31.40%) in textile dye bath samples. The maximum TDS removal (50-400 mg/l) was achieved by UV+FeSO4 for bleaching waste. The turbidity removal was improved up to 32.20% whereas polymer addition removes it upto 17.82% only. Finally 98.03% and 90.16% COD removal through UV+FeSO4 and by UV+O3 technique were attained respectively. AOPs are very effective, sustainable and environment friendly treatment methods for the industrial wastewater.
