The major problem concerning of environment in water pollution is from industrial wastewater problem which is the dyes pollution. Existing of dyes in the industrial wastewater will make the serious environmental problem due to its high toxicity. Azo dyes are the largest group of these dyes used in industry. Azo dyes are known to have the strong colour, high chemical oxygen demand (COD) and low biodegradability. The treatment of azo dyes industrial effluents in this research are by effects of hydrogen peroxide (H2O2), pH and ozonation time. It is continuing with the single-stage and multi-stage of advance oxidation process (AOP) and biological treatment. The AOP treatment selected is the combination of ozone and hydrogen peroxide (H2O2 ). The performance of AOP and biological treatment will be evaluated based on COD and biochemical oxygen demand (BOD) removal of Reactive Red 120 dye sample. In the single-stage and biological treatment, two (2) liter of dye was ozonated for 20 minutes and biodegraded with the 1% of river water for 4 days. In the multi-stage and biological treatment, the sample was ozonated for 10 minutes and biodegraded by the same method as single-stage treatment. Based on the research had done, the multi-stage AOP and biological treatment showed better results in COD removal which was 76.88 % compared to single-stage AOP and biological treatment which was 50.29 %. So, azo dyes are more efficiency treated with this AOP treatment than the other wastewater treatment process. 2013-02-17T03:11:55Z 2013-02-17T03:11:55Z 2011-04 Learning Object http://hdl.handle.net/123456789/23623 en Universiti Malaysia Perlis (UniMAP) School of Environmental Engineering |
