چکیده انگلیسی
In this study, the effect of sludge retention time (SRT) on oxic-settling-anoxic (OSA) process was determined using a sequencing batch reactor (SBR) attached to external aerobic/anoxic reactors. The SRT of the external reactors was varied from 10 to 40Â d. Increasing SRT from 10 to 20Â d enhanced volatile solids destruction in the external anoxic reactor as evidenced by the release of nutrients, however, increasing the SRT to 40Â d did not enhance volatile solids destruction further. Relatively short SRT (10-20Â d) favoured the conversion of destroyed solids into inert products. The application of an intermediate SRT (20Â d) of the external reactor showed the highest sludge reduction performance (>35%). Moreover, at the optimum SRT, OSA improved sludge dewaterability as demonstrated by lower capillary suction time and higher dewatered cake solids content.
