Atıksu arıtma tesisleri işletilmeye başlatıldığı tarihten bu yana hem kentsel hem de endüstriyel alanlarda çevre korunmasına katkı sağlamaktadır. Ancak konvansiyonel atıksu arıtma teknikleri modern bir sürdürülebilir kaynak yönetimi gereksinimlerini çoğunlukla sağlayamamaktadır. Bu teknolojilerinin ana özelliği nutrient ve karbon kaynağı gibi atıksu içinde bulunan değerli kaynakları ve kirleticileri ortadan kaldırılmaktır. Diğer bir deyişle konvansiyonel atıksu arıtma teknolojileri doğal kaynaklardan değerli nutrient kaynakların kaybına sebep olmaktadır. Özellikle yüksek su ve nutrient talebi olan bölgelerde, yenilikçi atıksu arıtma sistemleri ile değerli bileşiklerin kullanılmasını sağalamak gerekmektedir. Atıksu artık bir atık olarak görülmemeli, yeniden kullanılabilir ve değerli kaynakların bir karışımı olarak kabul edilmelidir. Suyun yeniden kullanımı tarımsal sulamada, çevre sulamada, endüstriyel geri dönüşümde ve yeraltı suyu geri beslemesinde umut verici bir kaynak olarak gösterilmektedir. Tüm bu uygulamalar arasında tarım en büyük bölümü temsil eder ve bu ihtiyaç gelişmekte olan ülkelerde yüksek bir ivmeyle artmaktadır. Bu projede, Türkiye'de atıksuyun yeniden kullanılabilirliğine yönelik yapılan potansiyel çalışması sonuçları ve belirli bölgelerde atıksuyun yeniden kullanılabilirliğinin teknoloji açısından değerlendirilmesi sunulmuştur. Yeni ve yenilikçi bir yaklaşım olarak, sunulan koşullar altında en iyi teknolojiyi belirlemek için modüler atıksu arıtma tesisi tasarımları gerçekleştirilmiştir. Bu bağlamda, farklı senaryolar için sistemlerin enerji tüketimi ve enerji üretimi; bunun yanı sıra yatırım ve işletme giderleri analiz edilebilir. Sonuçlar göstermektedir ki atıksuyun geri kullanımı özellikle tarımsal üretime katkı sağlamaktadır. 1.000 MWh’dan fazla enerji tasarrufu sağlanabilmekte ve tarımsal faaliyetlerde kullanılabilecek ek fosfor ve azot kaynağı oluşturulabilecektir. Sonuç olarak, eğer bir atıksu arıtma tesisi yapılacaksa veya bir tesiste değişiklikler öngörülüyorsa, modüler atıksu arıtma tesisi tasarımları kullanılarak geri kullanım açısından en uygun sistem seçilebilecektir.

Agricultural reuse of water and nutrients from wastewater treatment in İzmir Region Sarıkaya, Ebru; Demirer, Göksel Niyazi; Department of Environmental Engineering (2012) Rapid urbanization and population growth have represented a great challenge to water resources management, since wastewater generated in urban areas forms a non-conventional source, wastewater reuse is being recognized as a sustainable water management approach. This study focuses on with the potential and practibility of implementing wastewater reuse techniques in İzmir region, especially with the aim to use treated wastewater and nutrient for agriculture. To this end, qualititative and quantitative agricu...
Source Identification of Volatile Organic Compounds and Particulate Matters in an Urban and Industrial Areas of Turkey PEKEY, BEYHAN; PEKEY, HAKAN; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal; Arslanbaşı, Demet; BOZKURT, ZEHRA (2015-06-01) Elevated levels of volatile organic compounds (VOCs) and particulate matters have been observed in recent years in Kocaeli, Turkey, despite improvements in pollution prevention technology that have led to a reduction in gas and particulate emissions. Local authorities should devise alternative strategies to reduce the possible health effects of a variety of pollutants that affect air quality. The objective of this study was to identify potential sources of VOCs, fine particulate matter (PM2.5) and coarse pa...
Investigation of activated sludge bioflocculation : influence of magnesium ions Turtin, İpek; Sanin, Faika Dilek; Department of Environmental Engineering (2005) Activated sludge systems are the most widely used biological wastewater treatment processes all over the world. The main working principles of an activated sludge system are the oxidation of biologically degradable wastes by microorganisms and the subsequent separation of the newly formed biomass from the treated effluent. Separation by settling is the most troublesome stage of an activated sludge process. A decrease in the efficiency of the separation of microbial biomass from the treated effluent causes a...
Pollution haven hypothesis and the role of dirty industries in Turkey's exports Akbostancı Özkazanç, Elif; Tunç, Gül İpek (2007-04-01) The pollution haven hypothesis maintains that the industries that are highly pollution intensive, i.e. dirty industries, have been migrating from developed economies to the developing world. It is argued that the environmental concerns of the developed economies caused them to enact strict environmental regulations, which have increased the cost of production of the dirty industries at home. On the other hand, the developing countries with their low wages and lax environmental regulations have been attracti...
Silicon occurrence, uptake, transport and mechanisms of heavy metals, minerals and salinity enhanced tolerance in plants with future prospects: A review Imtiaz, Muhammad; Rizwan, Muhammad Shahid; Mushtaq, Muhammad Adnan; Ashraf, Muhammad; Shahzad, Sher Muhammad; Yousaf, Balal; Saeed, Dawood Anser; Rizwan, Muhammad; Nawaz, Muhammad Azher; Mehmood, Sajid; Tu, Shuxin (2016-12-01) Recently, heavy metals pollution due to industrialization and urbanization, use of untreated wastewater and unreasonable use of pesticides and fertilizers is increasing rapidly, resulting in major threat to the environment and contaminate soils. Silicon (Si) is the second most abundant element in the earth crust after oxygen. Although it's higher accumulation in plants, yet Si has not been listed as essential nutrient however, considered as beneficial element for growth of plants particularly in stressed en...
