“…In this calculation 68g COD/capita/day (equivalent to 1333 mg/lit COD) is taken as an average value for the estimation of methane production [18]. digestion processes is determined by hydraulic retention time [19] and the temperature. For tropical areas where temperature ranges from 20 o C to 35 o C, the anaerobic process holds prospects for the treatment of domestic wastewater [20].…”

Abstract-In this paper, we deal with biogas production potential from urban wastewater based on published information. The usual practice of the wastewater handling in urban cities of Nepal is either direct discharge into the rivers and streams or discharge into the septic tanks. In both cases adverse environmental impacts has perceived through directly polluting rivers and streams as well as releasing methane, ammonia and hydrogen sulphide to the atmosphere. In addition to that, the lost opportunity of biogas production along with potential carbon trading can be realized which also help to make the project economically and environmentally sustainable. An estimation of methane (CH 4 ) production and carbon emission reduction from urban wastewater are being done allowing wastewater treatment in an anaerobic baffled reactor (ABR) and upflow anaerobic sludge blanket (UASB). In this regard, average value of some pilot plant experimental results of efficiency of chemical oxygen demand (COD) removal at ABR and UASB from various studies have been taken into consideration. The estimated biogas production potential from urban wastewater is about 22 million m 3 / year equivalent to 14.5MW th, at the same time the carbon dioxide (CO 2 ) emission reduction potential is about 94,500 tons per year. An estimated revenue collection potential through fuel substitution is about 8 million USD per annum while additional benefits from GHG reduction and other improved condition of health, pollution and reuse of wastewater is significantly remarkable.Index Terms-Energy recovery, wastewater, anaerobic baffled reactor, upflow anaerobic sludge blanket, chemical oxygen demand.

With the increasing deterioration of world water resources, configuring a technical and economic viable wastewater treatment and recycle technology to satisfying the increasing complexity of wastewater and stringent environmental regulation has been a great challenge over the past decades. Developing reliable technologies for wastewater treatment is of urgent importance. In recent years, anaerobic baffled reactor (ABR) treating wastewaters effectively, have received considerable attention in the literature. This paper reviews the development and application, performance and characteristics, modeling of the ABR for wastewater treatment and the combination of ABR with other processes during the last decade. This paper provides a critical review on the ABR for treatment of refractory wastewaters. It was indicated that ABR had become a promising alternative for wastewaters treatment with great further development potential.

This laboratory research was carried out to evaluate the performance of a multistage anaerobic biofilm reactor, with six compartments and a working volume of 70 L, for the treatment of a strong synthetic nitrogenous and high-strength wastewater at an operational temperature of 26ºC ± 0.5ºC. Initially, the performance of the reactor was studied when subjected to an increase in the hydraulic retention time (HRT) at a constant influent COD concentration of 10000 mg/L. Five different HRTs were studied: 0.25, 0.67, 1, 3 and 5 days, which were equivalent to 6, 16, 24, 72 and 120 hours, respectively . By increasing the HRTs from 6 h to 1 day, COD and BOD removal efficiencies were increased from 63% to 84% and from 66% to 87%, respectively. Moreover, at an HRT of 3 days, COD and BOD removal efficiencies were equal, reaching 93%. In the second phase of the research, the effect of adding nitrate with a concentration of 3000 mg/L at an influent organic loading rate of 10 g COD/L·day was researched on the reactor performance and the amount of biogas produced. Denitrification took place almost solely in the first three compartments of the reactor, with efficiencies of 85%, 95% and 98%, respectively. The nitrite produced was only detected in the first and second compartments at concentrations of 138 mg/L and 24 mg/L, respectively. In addition, no accumulation of nitrite was detected in the reactor. Furthermore, the denitrification caused an increase in the total volume of produced biogas from 102 L/d to 178 L/d.
