Hızla artan nüfus ve azalan tatlı su kaynakları nedeniyle, atık suların uygun yöntemlerle arıtılarak çeşitli alanlardaki yeniden kullanımının sağlanması, günümüzün öncelikli çevresel konularından biri olarak kabul edilmektedir. Su kısıtının yarattığı global ölçekteki endişeler, arıtılmış atıksuların faydalı bir şekilde yeniden kullanılmasına yönelik çeşitli çalışmalara ve yaklaşımlara ön ayak olmuştur. Bu kapsamda, arıtılmış atıksuların bilhassa sulama suyu olarak yeniden kullanımının sağlanması, yaygın şekilde bir çözüm alternatifi olarak değerlendirilmektedir. Bu çalışmada, kablo üreten bir endüstriyel tesisin evsel nitelikli atıksularının paket arıtma ile arıtıldıktan sonraki özelliklerinin belirlenmesi ve paket atıksu arıtma tesisinden çıkan suların, sulama suyu olarak kullanımının yasal mevzuat çerçevesinde değerlendirilmesi hedeflenmiştir. Bu amaçla sulama suyu kalitesinin değerlendirilmesinde anahtar parametrelerden olan pH, elektriksel iletkenlik, toplam çözünmüş madde, sodyum adsorpsiyon oranı (SAR), nisbi sodyum iyonu yüzdesi (%Na), sodyum karbonat kalıntısı (RSC), sodyum, klorür, amonyum ve nitrat iyonları gibi parametreler standart yöntemlerle belirlenmiştir. Arıtılmış atıksu özelliğinde meydana gelebilecek zamana bağlı değişimleri izlemek üzere yılın farklı zamanlarında alınan atıksu örnekleri analizlenerek sonuçlar yorumlanmış ve Atıksu Arıtma Tesisleri Teknik Usuller Tebliği (AATTUT) ile literatürdeki çalışmalar baz alınarak, arıtılmış atıksuyun sulama suyu olarak kullanılabilirliği değerlendirilmiştir. Çalışma kapsamında elde edilen sonuçlar, incelenen evsel nitelikli arıtılmış ve dezenfekte edilmiş atıksuyun sulama suyu olarak kullanım potansiyeline sahip olduğunu göstermektedir. Kimyasal kalite kriterleri çerçevesinde bir değerlendirme yapıldığında, arıtılmış atıksu numunesinin, incelenen parametreler itibarıyla 2. sınıf sulama suyu olarak kategorize edilebileceği görülmüştür. Diğer bir ifadeyle, bu suyun kullanımıyla oluşacak zarar derecesi az-orta olarak sınıflandırılmıştır. Ayrıca elektriksel iletkenlik (EC) ve sodyum adsorpsiyon oranı (SAR) değerlerini baz alan ABD tuzluluk laboratuvarı sistemine göre yapılan sınıflandırmaya göre su numunesinin C3S1 sınıfına girdiği ve fazla tuzlu olmasından dolayı dikkatle kullanılması gerektiği tespit edilmiştir. Çalışma kapsamında yapılan ölçümler, evsel nitelikli atıksuların paket arıtma ile arıtıldığı tesiste, çıkış suyu kalitesinin zamana bağlı olarak küçük salınımlar gösterdiğini ancak sulama suyu sınıfını etkileyecek büyük bir değişimin meydana gelmediğini göstermiştir.
Due to the rapidly growing population and the decrease of freshwater resources, ensuring the reuse of wastewater in various areas by cleaning in appropriate methods is considered one of the priority environmental issues of today. The global concerns arising from water restrictions have led to a variety of studies and approaches to re-use of recycled waste in a beneficial way. In this context, the provision of reuse of recycled waste, in particular, as hydration water, is widely considered an alternative to the solution. In this study, the aim was to determine the properties of the home-quality waste of a cable-producing industrial facility after package treatment and to evaluate the use of the water out of the package waste treatment facility as hydration water in the framework of the legal legislation. For this purpose, the key parameters in the assessment of the water quality are pH, electrical conductivity, total soluble substance, sodium adsorption rate (SAR), relative sodium ion percentage (%Na), sodium carbonate residues (RSC), sodium, chloride, ammonium and nitrate ions are determined by standard methods. The results were interpreted by analysing the sample of waste taken at different times of the year to monitor the time-related changes that may occur in the refined waste characteristics and based on the studies in the literature, the availability of the refined waste as wheat water was evaluated. The results obtained in the study indicate that the examined home-quality refined and disinfected waste has the potential to be used as hydration water. When an assessment was carried out in the framework of chemical quality criteria, it was found that the processed waste sample could be categorized as the 2nd-class waters according to the parameters studied. In other words, the degree of damage that occurs by the use of this water is classified as low-mediate. According to the U.S. Salt Laboratory system based on the electrical conductivity (EC) and sodium adsorption rate (SAR) values, the water sample is classified as C3S1 and should be used carefully because it is too salt. Measures conducted in the framework of the study showed that in the facility where household quality waste was processed by packaging, the output water quality showed small emissions depending on time but there was no major change that would affect the water class.
Due to the rapidly increasing population and a reduction in freshwater supplies, evaluation of the reuse of appropriately treated wastewater in various areas are recently considered to be one of the prior environmental issues. Global concerns caused by the water constraint lead to a variety of studies and approaches to the beneficial reuse of treated wastewater. In this context, ensuring the reuse of treated wastewater especially as irrigation water is widely considered as a solution alternative. In this study, it is aimed to determine the characteristics of domestic wastewater of a cable producing facility after package treatment and to evaluate the reuse of the package wastewater treatment plant effluent as irrigation water within the framework of legal legislation. Accordingly, pH, electrical conductivity, total dissolved matter, sodium adsorption ratio (SAR), percentage of sodium ion (% Na), residual sodium carbonate (RSC), sodium, chloride, ammonium and nitrate ions which are among the key parameters for the evaluation of irrigation water quality were determined by standart methods. In order to monitor the time-dependent variation in the characteristics of treated wastewater, samples taken at different times of the year were analyzed, results were interpreted and the use of this treated wastewater as an irrigation water was evaluated according to Communiqué on Technical Procedures for Wastewater Treatment Plants and the related literature. The results obtained within the scope of the study indicate that the treated and disinfected domestic wastewater has the potential to be used as irrigation water. When an evaluation was made within the framework of chemical quality criteria, it was seen that the treated wastewater sample could be categorized as second class irrigation water according to the parameters examined. In other words, the degree of damage caused by the use of this water is classified as low to medium. In addition, according to the classification made according to the US salinity laboratory system based on the electrical conductivity (EC) and sodium adsorption ratio (SAR) values, the water sample is classified as C3S1 and should be used with caution because it is considered to be too salty. The measurements showed that the quality of the effluent water in the treatment plant where the domestic wastewater is treated by package treatment, shows only small variations depending on time but no major change that will affect the irrigation water class has occurred.
