INVESTIGATION OF COLIFORM BACTERIA REMOVAL EFFICIENCY IN THE URBAN WASTEWATER TREATMENT PLANT OF THE CITY OF SAKARYA

Abstract

In this study; SASKI Urban Wastewater Treatment Plant has been researched. Wastewater samples were taken periodically from the raw wastewater influent, physical treatment wastewater effluent, and plant wastewater discharge points of Urban Wastewater Treatment Plant. BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), SS (Suspended Solids), pH physical and chemical parameters and coliform and fecal coliform (FC) analyses were conducted on the wastewater. Also, eukaryotic microorganisms in the active sludge were determined. Effects of physical and biological treatment processes on removal of coliform and fecal coliform (FC) bacteria were investigated with regression model.
