Abstract: Anaerobic wastewater treatment, one of the oldest method is now used widely for the treatment of municipal and industrial wastewater. Anaerobic treatment offers a number of advantages i.e.: high treatment efficiency, low sludge production, low cost and methane production. Among the anaerobic treatment processes upflow anaerobic packed bed reactor (upflow anaerobic filter) system offers immense possibilities in developing countries particularly under Indian situations. Upflow anaerobic filters (UAFs) are reverse filters operating under submerged conditions. Upflow anaerobic filter was first introduced by Young and McCarty in 1969. UAF is a column filled with solid media. Anaerobic microorganisms grow on the media surface as well as inside the void spaces among the media particles. These microorganisms anaerobically degrade the organic matter present in waste water. The end products of anaerobic degradation are gases, mostly methane (CH4) and carbondioxide (CO2). In the present work, a bench scale upflow anaerobic filter was used for secondary treatment of domestic wastewater. The wastewater for study was collected from the outlet of a septic tank, constructed in residential colony of CBRI, Roorkee. Stones were used as a filter media. Filter was operated at four hydraulic loading rates i.e. 0.533, 1.067, 1.60 and 2.133 m3/m2.d. Influent and effluent samples were characterized daily for COD, BOD, TS, TDS, TSS, VSS, pH and temperature. Results from various experimental analysis infer that upflow anaerobic filter can very well be used for the secondary treatment of low strength domestic wastewater, for its safe disposal.
