Özet:

 This study aims to conduct a comparative analysis of the performance and cost efficiency of conventional and alternative dewatering technologies for the disposal of hazardous sludge generated from bilge water treatment in port waste reception facilities. In this context, three scenarios were evaluated through pilot-scale experiments: the conventional filter press system Scenario 1, filter press supported by ultrasound US Scenario 2, and filter press supported by US and coagulants Scenario 3. Experiments were performed using real bilge sludge samples with a volume of 5000 mL. US applications were conducted within a power range of 5002000 W for durations of 1060 minutes, while the coagulation phase tested different chemical groups, including polyaluminum chloride, ferric chloride, and demulsifiers. According to the results, US- and US  coagulant-assisted systems reduced sludge volume by approximately 10 and 15, respectively. However, despite the physical improvements, the increases in energy and chemical inputs resulted in higher total annual operating costs. Compared to the conventional method, Scenario 2 exhibited a 69.6 cost increase, while Scenario 3 showed a 65.2 increase. Furthermore, significant changes were observed in parameters such as total organic carbon TOC, loss on ignition LOI, and moisture content across all three scenarios. These findings suggest that while ultrasonic pretreatment positively influences sludge characteristics, under current economic conditions, such systems alone are not sufficient to reduce disposal costs effectively. Therefore, for full-scale applications, it is recommended that system efficiency, energy pricing, and potential environmental incentives be taken into account. Additionally, investigating hybrid technologies or advanced dewatering techniques that could further reduce sludge volume is critical for ensuring the long-term sustainability of disposal strategies.

 Bu çalışma, liman atık kabul tesislerinde sintine suyu arıtımı sonucunda oluşan tehlikeli nitelikteki çamurların bertaraf maliyetlerinin azaltılmasına yönelik olarak mevcut ve alternatif susuzlaştırma teknolojilerinin performans ve maliyet açısından karşılaştırmalı analizini amaçlamaktadır. Bu kapsamda, mevcut filtre pres sistemi Senaryo 1, ultrason US destekli filtre pres Senaryo 2 ve US  koagülan destekli filtre pres Senaryo 3 olmak üzere üç farklı senaryo pilot ölçekli deneyler ile değerlendirilmiştir. Deneylerde, gerçek sintine çamuru kullanılarak 5000 mL hacminde örneklerle çalışılmış; US uygulamaları 5002000 W aralığında ve 1060 dakika süreyle gerçekleştirilmiş, koagülasyon aşamasında ise polialüminyum klorür, demir III klorür ve demülsifier gibi farklı kimyasal gruplar test edilmiştir. Elde edilen sonuçlara göre, US ve US  koagülan destekli sistemler çamur hacmini sırasıyla 10 ve 15 oranında azaltmıştır. Ancak bu fiziksel iyileşmeye rağmen, enerji ve kimyasal girdilerdeki artış nedeniyle toplam yıllık işletme maliyetleri artış göstermiştir. Senaryo 2de yıllık maliyet, mevcut yönteme göre 69,6 oranında artarken; Senaryo 3te bu oran 65,2 olarak hesaplanmıştır. Ayrıca, her üç senaryoda da çamur içerisindeki toplam organik karbon TOC, kızdırma kaybı LOI ve su içeriği gibi parametrelerde önemli değişiklikler gözlenmiştir. Bu sonuçlar, ultrason tabanlı ön işlemlerin çamur karakteristiği üzerinde pozitif etkiler yarattığını, ancak mevcut ekonomik koşullarda bu sistemlerin tek başına bertaraf maliyetini azaltmak açısından yeterli olmadığını ortaya koymaktadır. Bu nedenle, tam ölçekli uygulamalarda sistem verimliliği, enerji maliyetleri ve olası çevresel teşvikler göz önünde bulundurularak yeniden değerlendirme yapılması önerilmektedir. Ayrıca, çamur hacmini daha da azaltabilecek hibrit teknolojilerin veya ileri susuzlaştırma tekniklerinin araştırılması, bertaraf stratejilerinin uzun vadeli sürdürülebilirliği açısından önem taşımaktadır.
