摘要

Brewery production process is one of the biggest economical sources in Ethiopia, there are different brands in beer industry in the country, such as Dashen, Balageru, Heineken, and Habesha Brewery Company, in such factories the modern technology treatment was performed in Habesha brewery. All beer industrial processes require large amounts of water and produce significant amounts of wastewater. Cleaner production is having an impact on these industries and today they are looking forward to zero discharge. In Habesha brewery, the generation of wastewater is coming under all departments, such as from brew house, filtration utility, and packaging rooms. The composition of brewery waste water effluent was sulphate, H_(2)S, CO_(2), sugar, and methane, etc. Habesha Brewery has given value highly the quality, taste, and drinkability of their beer. Production of methane from waste water during the treatment process was not applied in Habesha brewery industry due to the low treatment of methane and lack of technology to recover methane as an energy source. Through anaerobic digestion of organic waste materials provides an alternative environmentally friendly renewable energy. Methane production from digestion of brewery wastewater was improved using chemical methods, using aspen plus dynamics simulation the model of methane production recovery system was modelled, and brewery waste was taken into the reactor in its own behavior was evaluated under atmospheric conditions, 25°C, 30°Candat 1 atmosphere. For all substrates, total solids, biological oxygen demand, chemical oxygen demand, temperature, total nitrogen, total phosphorus, and pH were measured before and after digestion. Wastewater by volume was taken fully into the digester. All measured physico-chemical parameters of the sample substrate significantly varied before and after anaerobic digestion. Methane was measured for all samples periodically starting from the effluent was started. In all substrates. Assessment of cumulative methane production revealed that the substrate at a temperature 30°C, pH 6.5 (0.0013 hl /0.008 hL sample of waste water) and after 4 days sample 25°C, PH 7.5 (0.001625 hL/0.008 hL sample) showed the highest Methane production and the lowest was in the last day volume waste water, 35°C temperature and pH of 6 (0.00125 hL/0.008 hL sample of waste water). The results indicated that the methane amount was affected by H_(2)S, CO_(2), sugar, and other behaviors of brewery waste water effluent during the digestion process.
