In this study, the method which could provide the proper operation condition for abnormal conditions at sewage treatment plant was suggested. For this analysis, the operating data of one year of 2011 has been collected from a sewage treatment plant for the media process. The abnormal condition was set up the winter season and the rainy periods. The multiple regression analysis was divided with 4 CASE according to the removal of outliers and the log transformation of variables. The criteria for operation conditions was set to 60% of water quality standards in CODMn, T-N considering the safety factor. As a result of this study, the proper operation condition for abnormal conditions at sewage treatment plant could be provided by multiple regression analysis. The sewage treatment plant that is collected operation data for this study was being operated within the proper operation range that is provided by multiple regression analysis. KCI Citation Count: 0
