ABSTRACT This study aims at the presentation of dairy waste treatment methods, one of the main industries in Greece with emphasis on biogas production. The industry of dairy products constantly grows due to the increasing demand for milk and its products. Also, the milk production per animal has increased. The dairy industry is one of the largest industrial sources of waste in Europe. A plant can produce over 500 m3 of wastewater per day. First, there is a demonstration of the production processes of a dairy plant with the requirements of one industry in water and energy to understand the "source" of waste from a dairy factory, showing the significance of having biofuels in reducing environmental pollution, appropriate waste management and various options of their utilization. Then, the waste resulting analysis, of solids, liquids and gases, is studied, giving greater prominence to analysis of wastewater. The quantitative and qualitative characteristics of waste water are examined as well. The liquid wastes in a dairy not only come from production processes but also from pickling premises and mechanical equipment and from milk whey losses and discharges. In addition, analysis of the wastewater treatment methods, with greater emphasis in the anaerobic, treatment is included. Finally, an essential case study based on a real waste data for waste production of a dairy plant, is discussed in details. |
