Abstract:

The study examined the removal efficiency of upflow anaerobic filter reactor fed continuously with campus domestic wastewater at different hydraulic retention time and wastewater temperature. The reactor was filled with non woven filter materials and operated at hydraulic retention time ranging from 1 to 6 days and wastewater temperature ranging from 20 to 30C. At that operating condition, the result revealed no significant difference for Carbonaceous (COD) and nutrients materials except there was significant production of gas. The result revealed that increase in HRT and wastewater temperature improves removal performance of the reactor. The overall reactor removal efficiency for COD, TN, NH4+-N, NO3-N and TP concentration were 51, 22, 21, 28 and 10% and 61 35, 37, 49 and 27% in the anaerobic and anoxic columns, respectively. The experimental system was capable of instantaneous removal of the carbonaceous, nitrogenous and phosphorous compounds.
