Industries use reclaimed water for their makeup water requirements of cooling towers to decrease their water footprints. Makeup water quality depends on the type of cooling tower design; however, total suspended solids (TSS), biological oxygen demand (BOD5), fecal coliform, pH, total dissolved solids (TDS), some ions (sulphate, chloride, ammonium)...
This study aimed to examine the digestibility of anaerobic co-digestion of thermally pre-treated waste activated sludge (WAS) and dairy industry wastewater (DW). To identify the optimal pre-treatment conditions, the biomethane potential (BMP) test will be performed for thermally pre-treated WAS samples at three different temperatures (60°C, 90°C, a...
This study investigates the impact of inoculum sources on the anaerobic digestibility of dairy industry wastewater (DW), a significant byproduct of one of the largest food sectors. Using a Biochemical Methane Potential (BMP) assay, two different inoculums—one from a municipal wastewater treatment plant and another from a dairy wastewater treatment...
The challenges associated with textile wastewater treatment and the need for advanced technologies are to address the increasing water stress caused by population growth, industrialization, and agricultural activities. Textile wastewater contains high concentrations of dyestuffs and chemicals, making it difficult to meet stricter discharge limits....
"Bilindiği üzere iklim değişikliği temelde sanayi devrimi sonrasındaki endüstrileşme ve buna bağlı olarak karbon kaynaklı enerji kaynaklarının sınırsızca tüketilmesine dayanan ve etkilerini daha çok son yarım yüzyılda atmosferik olaylar ile hissedebildiğimiz bir olgu haline dönüşmüştür. Yağış rejimlerinin değişimi ve sıcaklık artışı sonucunda daha...
Recently, palladium is widely used in electronics, catalysis, electroplating, and fuel cells. The recovery of precious metals has become very important due to their scarcity and high price. The adsorption method which is generally used in polymer inclusion membranes is both effective and simple because, for that reason, the retention and mechanism...
In this study, cellulose acetate (CA)-based nanofiltration membranes, modified with zeolitic imidazole framework-8 (ZIF-8) particles, were prepared with various ZIF-8 contents (0, 0.1, 0.25, 0.5, 1 and 2 wt%), to obtain membranes with improved flux and filtration performance by combining advantages of CA polymer and ZIF-8 metal-organic frameworks....
The performance of ultrafiltration (UF) is heavily influenced by the specifications of membrane modules and operational modes. Pore size, configuration, and material of the UF membrane influence both treatment and filtration performances. The study compares the performance of outside-in and inside-out UF membrane configuration in a pilot-scale syst...
In this study, impact of different inoculum on the performance of membrane bioreactors (MBRs) was investigated for municipal wastewater treatment. Waste sludges from a conventional activated sludge (CAS) system and a high-rate activated sludge (HRAS) system were used as inoculums at Stage-1 and Stage-2, respectively. A commercial ultrafiltration (U...
Pre-concentration and separation processes of Rare Earth Elements (REEs) were investigated in terms of several factors. Nitric acid leachate of e-waste was first pre-treated by increasing pH and filtering through microfiltration. For pre-concentration, pre-treated leachate was concentrated by nanofiltration. While a 70% permeate recovery ratio was...
Vacuum-assisted air gap membrane distillation was used to remove boron from different waters in this study. Four different vacuum pressures (0.02 bar, 0.04 bar, 0.06 bar, and 0.08 bar) were applied and air gap membrane distillation (AGMD) configuration was also used to compare the effect of vacuum pressures on the process. Six commercial hydrophobi...
Limited natural resources and a continuous increase in the demand for modern technological products, is creating a demand and supply gap for rare earth elements (REEs) and Sc. There is therefore a need to adopt the sustainable approach of the circular economy system (CE). In this review, we defined six steps required to close the loop and recover R...
E-waste (EW) from discarded electrical and electronic devices is a potential source of rare earth elements (REEs) that might be recovered from urban and industrial wastes. REEs are essential raw materials for emerging and high technologies. China currently dominates global REE production with a proportion of 97%. To increase the independence of REE...
It is now inevitable to reuse the wastewater in urban areas in terms of climate change and circular economy. The aim of this study is to evaluate the reuse of secondary treatment as irrigation water and/or industrial process water by pilot-scale ultrafiltration (UF) and reverse osmosis (RO) units. The conductivity, pH, organic matter, heavy metals,...
Rare earth elements or REEs are a vital and irreplaceable part of our modern technological and digital industries. Among the REEs that are the most critical to be recovered are Ce, La, and particularly, Nd, and Y, due to high demand and at a potential future supply risk. Innovative techniques must be considered to recover REEs from secondary resour...
The removal performance of boron from real wastewater was conducted to determine the effect of different parameters on permeate water flux and boron removal efficiency by air gap membrane distillation (AGMD) system in this study. These parameters include boron concentration, membrane pore size, and membrane material. Before real wastewater tests, t...
REEs are essential materials for modern technology due to their unmatched physical and chemical properties. This paper reviews the potential and types of rare earth elements (REE) in 32 different secondary sources that contain water, wastewater, and slime/solid wastes originating from Turkey. Secondary sources were classified into five different ca...
Membrane bioreactors (MBR) with osmotic pressure driven membranes have significant
advantages over bioreactors operated with pressure driven membranes. Since no pressure is applied to
the membrane, except the concentrate circulation, osmotic membranes are less prone to fouling.
Membrane fouling is an important limiting factor in MBRs, resulting in...
In the present study, three different real wastewaters (containing high boron concentration between 2500–6200 mg/lt) were treated using the vacuum assisted air gap membrane distillation (VA-AGMD) system through the use of polypropylene with a pore size of 0.20 μm (PP 0.20), polypropylene with a pore size of 0.45 μm (PP 0.45), polytetrafluoroethylen...
In this study, a novel osmotic membrane was developed by polyamide (PA) coating on the tubular electrospun nanofiber (TuEN) support membrane. Water and reverse salt flux properties of the obtained membrane were investigated by applying pressure in addition to the osmotic forces. Surface characterization of the membrane was carried out by Fourier-tr...
