The aim of this study is to evaluate the parameters such as pH, dissolved oxygen, temperature, conductivity, salinity, biological oxygen demand (BOD), total suspended solid, ammonia, chlorophyll-a and heavy metals affecting coliform values in seawater using Artificial Neural Network (ANN) modelling at Eastern Black Sea coast Turkey. results obtained from ANN model were compared with actual values. samples taken different points selected along deep sea discharge systems starting diffuser end...

This study focuses on adsorption of lead (II) using various inexpensive adsorbents, such as dried activated sludge, diatomite, and sepiolite, through the batch process. The data were evaluated three types isotherm models to determine design parameters. Additionally, kinetics was analyzed first- second-order kinetics. regression coefficient (R2) quantitatively evaluates correlation between experimental predicted responses. Box–Behnken factors at levels used important parameters affecting by...

In this work, the most common heavy metals such as Cu (II), Zn and Pb (II) removal from aqueous leachate of industrial waste were investigated using pure biochar rice husks. The influence parameters pH, adsorbent dose (g L–1), contact time (min) on biosorption was examined by response surface methodology (RSM) based upon Box-Behnken statistical design at a leaching solution, Ci = 32.69 g L–1 fixed input parameter. results show that both linear squared terms process variables are found...

The TR83 region in Türkiye is recognized as one of the leading industrial centers Black Sea with its efficient use resources and wide range activities. In project carried out jointly by University Central Development Agency, potential for optimizing resource sector was evaluated to demonstrate circular economy applicability. Research conducted determine current situation draw up a road map future. These surveys followed comprehensive field survey, where data processed analyzed guidance...

Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," are persistent synthetic compounds that have been widely utilized since the mid-20th century across various industries. Due to their environmental persistence potential health risks, PFAS has become a significant concern, particularly in relation water wastewater contamination. This paper investigates complex challenges associated with PFAS, focusing on existing regulatory frameworks, treatment strategies,...

This study considers green port-based strategies that improve environmental performance in the context of urban areas and promote sustainable solutions to combat climate change. As an important component city, ports have a significant impact on socioeconomic development. In fact, given Turkey operate limited spaces city centers, pollution from port operations has direct both life workers. recent years, approach become increasingly within scope change adaptation programs. Particularly Turkey,...

The main goal of the present work was to search feasibility pumice and vermiculite as adsorbents for lead (II) removal from industrial waste by using Box-Behnken method. Batch adsorption method performed evaluate feasibility. surface statistical design approach with three inlet parameters namely pH (2, 5, 8), adsorbent concentration (10, 50, 100 mg L–1), contact time (5, 30, 120 min) conformed optimising experimental conditions process. Experiments were carried out regression analysis...

Günümüze bakıldığında plastikler yarı sentetik veya bileşiklerden yapılan, kolay şekil verilebilen, üretiminin olması, suya, kimyasal maddelere ve çevresel değişimlere (ışık, sıcaklık vb.) karşı duyarlı olması sebebiyle kullanımları oldukça geniş bir yer tutmaktadır. Üretime paralel olarak artış gösteren plastik atık kirliliği de hem çevreyi fosil yakıt kaynaklarını önemli ölçüde tehdit etmektedir. Gelişen çevre bilinci ile birlikte daha dostu malzemeler olan biyoplastiklerin bu konuda...

Ecological processes that occur in a lake depend on the physico-chemical (abiotic) and biotic factors of system interrelations between them. It can be concluded current nutrient loadings from both point non-point sources are cause to increase eutrophic case over years. This study indicate sustainable utilization reservoir combination with proper wastewater treatment plant controlled use pesticides has potential reduce into Suat Uğurlu Lake. The estimated reductions could achieved management...

Constructed wetlands (CWs) are a green technology that have been used to treat several types of wastewater such as domestic, industrial, agricultural wastewaters and landfill leachate. CWs advantages included land intensive, low energy, easy operation maintenance, investment/operational costs, landscape esthetics, reuse waters, increased wildlife habitat compared conventional systems. alternative treatment technologies due these properties especially for rural settlements, industries, hotels...

Bu çalışmanın amacı biyokütlenin kopiroliz sırasında plastikler üzerindeki etkisini araştırmaktır. Kereste tozlarının (SP), polietilenin (PE) ve bunların karışımlarının pirolizi, 550 °C 600 değişen sıcaklıklarda yarı-kesikli bir reaktörde gerçekleştirildi. çalışma, endüstriyel kullanım için alternatif sıvı yakıt üretmek amacıyla, biyolojik kütle ile plastik atıkların işlemini geliştirilmesi ön çalışmadır. Bileşenlerin kopirolizi biyokütle arasında meydana gelen etkileşimleri vurgulamak için,...

Waste characterisation is shown as the first step of a successful waste management policy. Many stages such reduction at source, separation according to property, collection, temporary storage, recovery, transportation, disposal and control must be carried out regularly effectively. The studies were determine amount solid wastes generated produced in Ondokuz Mayıs University (OMU). According data, total production per week was calculated 8,597 kg/week. university, distribution rates are 51%...
