Anaerobic Treatment of Distillery Wastewater
نویسنده
چکیده
The estimated global ethanol production in 2009 was about 74 mln m. After fermentation remains waste from bottom of distillation columns, termed stillage. This highly aqueous residue containing organic solubles is considered a troublesome and potentially polluting waste due to its extremely high BOD and COD values. Moreover, for each liter of produced ethanol 8 -15 liters of stillage are generated on average. The possibility of anaerobic treatment of distillery stillage was analyzed.

Effect of initial pH on biodegradation of distillery wastewater by batch process using anaerobic mixed consortia
Biodegradation of distillery wastewater is dependent on initial pH. In this present research, the effect of initial pH from 5.0 to 6.5 on biodegradation of distillery wastewater using anaerobic mixed consortia by batch process was investigated. The parameters like chemical oxygen demand (COD) removal efficiency, oxidation reduction potential (ORP), final pH, total phenol content, total protein ...
متن کاملAnaerobic Methods of Distillery Waste and Wastewater Treatment
During alcohol production, large amounts of waste and wastewater are produced. These may have a considerable environmental impact by polluting both water bodies and soil, by causing an adverse climatic effect and odour nuisance. Due to the high concentration of organic matter, both distillery waste and wastewater at the same time do have a great nutrient and energy potential that can be utilise...
متن کاملUpflow Anaerobic Sludge Blanket (uasb) Reactor in Wastewater Treatment
Under anaerobic conditions, organic pollutants in wastewater are degraded by microbes producing methane and carbon dioxide. The degradation process is effective compared to the more conventional aerobic processes and produces only 5-10% of sludge. This saves considerably on cost associated with the sludge disposal. Among anaerobic technologies, the most popular ones is the upflow anaerobic slud...

An efficient microbial technique for decolorizing distillery wastewater was achieved using irradiated spores of Aspergillus fumigatus. The fungus was isolated from soil samples taken from the local distillery processing unit. By using the irradiated spores, wastewater decolorization increased by 14.3% as compared to that of the control treatment (68.8% vs. 54.5%). In the presence of sodium nitr...
