Dairy Wastewater Characterization and Process Simulation for Producing Ethanol from Cheese Whey
Session
Food Science and Technology
Description
The dairy industrial plants usually run in continuous operation procedure and they produce except main products: different content of fat milk, pasteurized products of it, butter, cheese and a great amount of wastewaters is continuously discharged into streams, rivers, and seas. There wastes not only contaminate the environment, but they have some ingredients usable to produce some profitable materials such as Ethanol. Our experimental works of this work has been focused in finding the proper way to simply characterize these dairy wastewater and trying to perform a suitable process simulation for transforming the cheese whey into ethanol content. Our main purpose of this work has been to determine the nutrient contents in the waste whey deriving from the cheese production, and later we have tried to follow a tentative a little complex process to profit 95% pure of Ethanol. Except the experimental works for characterization of the dairy wastewater, we have performed a process modeling and simulation using Super Pro Designer computer software. From this calculation practice, we have found the ethanol producing yield from spent whey, and which is the most important, we have made a plant design and performing almost all material and energy balances, relevant component composition, cost analysis and economic evaluation, environmental impact and emissions related to this producing activity. Of course, during alcoholic fermentation it can be observed a release of carbon dioxide, and there is an environmental load which can be monitored through such parameters as: COD, TOC, BOD5, TSS etc. We have been focused on bio-ethanol production as a promising alternative fuel. From the results of these calculations it can be shows that applying simulation procedure can be reached in a positive situation for reasonable recommendations in the industrial production practice.
