Anaerobic Treatability of Cane Molasses Based Bio-Ethanol Distillery Wastewater Mixed with Cane Sugar Mill Wastewater by Two Phase Multi-Stage Upflow Anaerobic Sludge Blanket Reactor
In a period of 1 year, the volumetric ratio of wastewater from a cane molasses-based bio-ethanol distillery plant (CMBP) and a cane sugar mill (CSM) was monitored and shown to be 1:2. In order to evaluate the validity of mixing the two wastewaters, their biodegradability and methanogenic activity (MA) were measured under a fixed temperature of 35°C and fixed FM ratio of 0.5 (i.e., 2 g COD/l for...
متن کاملAnaerobic Treatment of Distillery Wastewater
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 genera...
متن کاملTwo-stage anaerobic process treating high concentration methanol wastewater and
In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...
متن کاملModeling the Two-stage Anaerobic Digestion of Domestic Wastewater with the Development of a Monitoring Application
The IWA Anaerobic Digestion Model No. 1 (ADM1) was chosen to simulate a two-stage anaerobic digestion lab-scale plant treating domestic wastewater. Initially, the model was preliminary tested using synthetic wastewater. The simulation results were satisfactorily compared to NH4 and chemical oxygen demand (COD) data for the first and second stages, respectively. A transformation method was then ...
متن کاملInterfacing the Iwa Anaerobic Digestion Model No.1 (adm1) with Manure and Solid Waste Characteristics
An interface to ADM1 was developed to estimate the solid waste composition from its practical characteristics. The interface was based on COD, elemental, charge and covalent bond balances to conceal any error in collected characteristics from different sources. The interface was validated by reported characteristics of manure and food wastes and determined with relevant accuracy the wastes’ com...
