Abstract

The purpose of this study was to analyze the performance of Integrated Fixed Film Activate Sludge system in Amol industrial wastewater treatment plant to treat the food industrial wastewater. The capacity was 1700 cubic meters per day that includes physical and biological treatment, disinfection, sludge thickening, digestion and dewatering. The wastewater quality parameters were analyzed during winter 2010 and spring 2011. Using data, COD REMOVAL efficiency and kinetic coefficient such as yield coefficient (Y), half saturation coefficient (Ks), maximum substrate utilization rate (k) and endogenous decay coefficient (kd) were calculated and results indicated that except Ks other coefficient were in the range that was normally reported for conventional activated sludge. Under existing conditions at the wastewater treatment plant, COD REMOVAL efficiency range was between 98 to 99 percent. By using kinetic coefficient obtained in this study, effluent COD was estimated and sensitivity analysis was performed. The results showed that there is a direct relationship between the variation of kd and Ks with effluent substrate concentration, while the relationship between k and effluent substrate is reverse. Finally the effect of increasing sludge retention time (SRT) on COD REMOVAL efficiency was also investigated.
