Istanbul Water and Sewerage Administration (ISKI) has embarked on a programme to build twelve sanitary wastewater treatment plants as well as regulating industrial effluent discharges to sewerage system and imposing a pretreatment program An industrial waste sludge management study was performed as a part of the sludge management efforts for the City of Istanbul In this study, over 1,500 industries with a wide variety of activities in the project planning area have been identified and categorized considering their proximities to the Publicly Owned Treatment Works (POTWs) Since there was little data on industrial sludge, productions were calculated through a three step process which consisted of wastewater characterization, sludge production identification process typically employed to meet pretreatment standards and development of sludge production formulas An important part of the study was the classification of industrial sludges as hazardous or non-hazardous. Identifications were made in accordance with the US Code of Federal Regulations and wastewater characteristics and treatment processes were evaluated Economic and noneconomic analysis were conducted in order to evaluate the possibility of joint treatment of nonhazardous compatible iiudge with the sanitary sludge. Unit costs for joint treatment at each POTW were calculated and it is found that administrative burdens and liability would be the prime concern as opposed to the economic factors
