The Integrated Pollution Prevention and Control (IPPC) Directive from the European Union strives to achieve a high level of environmental protection by preventing or reducing the pollution emanating from industrial installations directly at the source. The Directive implies that the emission limit values should be set in accordance with each industry’s Best Available Techniques (BAT). In the present study, water recovery and wastewater treatability alternatives developed beforehand were evaluated towards the evaluation of BATs for the management of wastewaters from a denim textile mill. For this purpose, an assessment that translates the key environmental aspects into a quantitative measure of environmental performance and also financial analysis were performed for each of the alternatives. The alternatives considered for water recovery from dyeing wastewaters were nanofiltration (NF) with coagulation and/or microfiltration (MF) pretreatment, ozonation or peroxone and Fenton oxidation. On the other hand, for the end-of-pipe treatment of the mill’s mixed wastewater; ozonation, Fenton oxidation, membrane bioreactor (MBR) and activated sludge process followed by membrane filtration technologies were evaluated. The results have indicated that membrane filtration process providing 70 % water recovery with the least environmental impacts is the BAT for water recovery. On the other side, MBR technology has appeared as the BAT for the end-of-pipe treatment of the mill’s mixed wastewater. A technical and financial comparison of these two BAT alternatives revealed that water recovery via membrane filtration from dyeing wastewaters is selected as the BAT for the water and wastewater management in the mill.

Improvements in energy and water consumption performances of a textile mill after bat applications Kocabaş, Ayşe Merve; Yetiş, Ülkü; Department of Environmental Engineering (2008) European Union’s Integrated Pollution Prevention and Control (IPPC) Directive forms a comprehensive framework for industries mentioned in the Annex 1 of the Directive concentrating on the reduction of the environmental impacts of the industrial activities which can be implemented by the BREF Documents that provide guidelines for each sector. Among those industries, textile is a water and energy intensive one. In the present study, gains in terms of energy and water consumptions were assessed in a denim prod...
Investigation of PCB pollution: method validation and case studies from Ankara Akduman, Nazan; İmamoğlu, İpek; Department of Environmental Engineering (2009) Polychlorinated biphenyls (PCBs) are persistent organic pollutants which were not produced in Turkey, however both national and international studies illustrate a measurable amount of PCB pollution in receiving environments, aquatic fauna and people. In this study, various information sources such as the national and international scientific literature, official records and reports are investigated to obtain information regarding PCB pollution in Turkey. Furthermore, various PCB pollution analysis technique...
Comparison of iscst3 and aermod air dispersion models: case study of cayirhan thermal power plant Dölek, Emre; Atımtay, Aysel; Department of Environmental Engineering (2007) In this study, emission inventory was prepared and pollutant dispersion studies were carried out for the area around Çayırhan Thermal Power Plant to determine the effects of the plant on the environment. Stack gas measurement results were used for the emissions from the power plant and emission factors were used for calculating the emissions from residential sources and coal stockpiles in the study region. Ground level concentrations of SO2, NOx and PM10 were estimated by using EPA approved dispersion model...
Investigating the CO2 emission of Turkish electricity sector and its mitigation potential Arı, İzzet; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2010) The rapid industrialization, population growth, urbanization and economic and social development cause many environmental problems, such as climate change which is the result of the increase in the emission of greenhouse gases (GHGs) especially CO2. Combustion of fossil fuels, particularly from electricity generation, has the major responsibility for CO2 emissions. Decreasing the amount of CO2 emission requires a significant shift from our present energy use pattern toward one of lesser reliance on fossil f...
Identification of waste management strategies and waste generation factors for thermal power plant sector wastes in Turkey Demir, Cansu; Yetiş, Ülkü; Ünlü, Kahraman (SAGE Publications, 2019-03-01) Thermal power plants are of great environmental importance in terms of the huge amounts of wastes that they produce. Although there are process-wise differences among these energy production systems, they all depend on the logic of burning out a fuel and obtaining thermal energy to rotate the turbines. Depending on the process modification and the type of fuel burned, the wastes produced in each step of the overall process may change. In this study, the most expected process and non-process wastes stemming ...
