| Background and Aim: Millions of liters of color effluents are produced by textile industries and plants. Every liter of effluents may contain more than 20gr of pigments and mediators produced by their degradation which can result in environmental problems. Chemical dyes used in textile industries have some potential risks including carcinogenic and mutagenic effects on human. Further, these dyes can penetrate into surface and ground water. The aim of this study was to investigate the efficiency of combined CAC-SBR system for removal of Reactive yellow 3 dyes.
Materials and Methods: This experimental study was conducted based on a batch scale, and two SBR reactors were used for the experiment. We used synthetic wastewater samples in this study (COD=1800). After adjusting the reactors, reactive yellow3 dye was injected into the system and its removal efficiency was investigated during different reaction times. Then SBR system efficiency in dye and COD removal was determined.
Result: After 24 hours of reaction, the efficiency of SBR system in the removal of reactive yellow3 dye was 58%. But the efficiency of SBR system in COD removal was 98% after 14 hours of reaction.
Conclusions: In this study, by increasing the reaction time SBR efficiency increased and stabilized in a distinct time. SBR efficiency in the removal of dye and COD, together with high efficiency of anaerobic system in dye removal reveals that a combination of aerobic and anaerobic systems can be suitable for synchronic dye and COD removal. |
