Biological treatment of an industrial estate wastewater in a continuous feed and intermittent discharge SBR (CFID SBR

In this study, the performance of an upflow sludge bed bioreactor (USBR) with intermittently aerated removing carbon and nutrient (N & P) from Faraman’s industrial wastewater (FIW) was investigated. This study was performed by varying two significant independent variables viz. HRT (4-12 h) and aeration time (40 and 60 min/h). Eight dependent parameters as the process responses were measured and calculated. The results showed that the maximum value of total COD (TCOD) removal was obtained to be 76 % at the highest value of the factors (12 h and 60 min/h). The maximum values of total nitrogen (TN) removal efficiency were found to be 62 % at HRT of 12 h and aeration time of 40/60 min/h.
