Abstract:

The microbial bed fixed upflow sludge blanket filtration (USBF) system was operated for about 100 days and runs of steady state data were collected. The results showed that the USBF system had a better ability in terms of organic matter and nutrients removal. In this study, the removal of pollutants from piggery wastewater was evaluated in the advanced USBF reactor at hydraulic retention time (HRT) of 6-15 hours and solid retention time (SRT) of 20 day. Experimental studies indicated that average removal efficiency of pollutants with HRT of 12 hours. The results show that the average removal efficiencies for Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) were over 94.2% and 93.3% respectively. The phosphorous and nitrogen’s removal were found to be 79.7% and 85.1% respectively. The advanced USBF as an advanced biological process had a pollutants removal efficiency from piggery wastewater.
