Abstract

In this study, a detailed wastewater profile and treatability studies of Demirtas Organized Industrial District (OID) were undertaken on a pilot-scale. The industrial categorisation of Demirtas OID was determined, and the wastewater characterisations of each industrial sector were analysed and the flow-rates were measured. The results were used to design a wastewater treatment plant for Demirtas OID. Pilot-scale chemical and biological treatability studies were carried out. The steady-state performance of the pilot-scale treatment system in removing chemical oxygen demand (COD) and suspended solids (SS) was studied for a period of three months. The removal efficiencies obtained in this study were 42% of COD and 67% of SS in the chemical treatment, and 84% of COD and 25% of SS in the biological treatment. The overall removal efficiency of the pilot-scale system was 91% COD and 75% SS. The pilot-scale study showed that the wastewater from Demirtas OID could be treated with biological and chemical methods, and the treated wastewater met the Regulation of Discharge Standards of Turkey. The significance of this study is that it is the first such system in Turkey to be tested on a pilot scale.

Abstract

WOS: 000184092600006, The textile industry is one of the most rapidly developing industries in Turkey. It generates a large amount of wastewater, with corresponding concerns about pollution. The main sources of pollution in wastewater are the dyeing and finishing processes. The dyestuffs and polyvinyl alcohol (PVA) are the main refractory organics of concern in terms of meeting more stringent effluent standards of chemical oxygen demand (COD) and colour. In this study, wastewaters from textile dyeing factories in Bursa were characterized, and physical, chemical and biological treatability studies were carried out. In the physical and chemical studies, 60-80% COD, 80% suspended solids (SS) and 10-92% turbidity removal efficiencies were obtained. In the biological studies, 90% COD and 40% SS removal were obtained. The initial soluble inert COD of wastewater was determined by using comparison methods. The initial inert COD of wastewater and the microbial product concentration were determined as 37 mg/I and 13 mg/l, respectively.
