Abstract
To find out the major cause of scale formation in digestion facility, a componential analysis of scale and a digestion experiment for food wastewater were conducted. The analysis indicated that grease in food wastewater was closely connected to the organic component of scale. It is also indicated that grease-removed food wastewater showed 58.9% level compared to unprocessed one in crystal generation quantity in this study. The experiment provided insight that grease is one of the important causes of scale formation. Additionally, pre-removal of grease from food wastewater did not show negative effect on digestion gas production, as 68.7 L-gas/kg-COD for grease-removed food wastewater and 67.7 L-gas/kg-COD for unprocessed one.
