Textile finishing industry wastewaters contain micropollutants such as endocrine-disrupting chemicals in addition to the conventional pollutants since advanced manufacturing activities provide additional features to the textiles to make them shrink-proof, water-proof, wrinkle-proof, rot-proof, distasteful to moths, and mildew, flame-resistant, etc. Endocrine-disrupting chemicals can interfere with the endocrine system, exert endocrine-modulating behavior, and cause adverse health effects, even when exposed to low doses. Therefore, treatment of endocrine- disrupting chemicals is a major concern for textile finishing wastewaters since they cannot be completely removed by widely applied conventional treatment technologies; but rather by using membrane filtration, advanced oxidation, and adsorption technologies. This study aims to investigate the performance of nanofiltration membranes in the post-treatment of endocrine-disrupting chemicals in textile finishing wastewaters. A total of 299 chemicals that were identified as endocrine-disrupting chemicals present and/or likely to be present in surface waters of Turkey were monitored in a textile finishing wastewater, and their removal by nanofiltration was investigated. The experimental results showed that 10 of the 17 compounds determined in textile industry treatment plant effluent, including benzo (g,h,i) perylene, fluorene, phenanthrene, mono-2-ethylhexylphthalate, dicyclohexylphthalate, diethyl-phthalate, di-n-butylphthalate, octamethylcyclotetrasiloxane, mirex (perchloropentacyclodecane) and saccharin were treated below their limit of detection values with nanofiltration. On the other hand, it was determined that nanofiltration was not efficient for compounds such as naphthalene, mono-n-butylphthalate, and di-sec-octylphthalate.

Preparation of antimicrobial films from agricultural biomass Seber, Ayşe Gizem; Bakır, Ufuk; Department of Biotechnology (2010) Mainly used food packaging materials are petro-chemical based polymers which present environmental problems since they are not biodegradable and ecologically sustainable. In this study, biodegradable biofilms are produced from xylan, extracted from cotton stalk which is an agricultural biowaste without nutritional value. Antimicrobial property was given to the biofilms with either titanium dioxide sol-gel coatings or titanium dioxide powder addition into the biofilm forming solutions. The antimicrobial acti...
Characterization of local flow behaviour in conical spouted beds Yeniçeri, Ali; Külah, Görkem; Department of Chemical Engineering (2019) Conical spouted beds are used in various physical and chemical applications such as drying, coating, and pyrolysis of waste plastic and biomass owing to their effective feature of gas-solid contact. To design and operate these units in high efficiency, a complete understanding of the phenomena and detailed investigation of local flow structure are of paramount importance. In this study, the effects of bed design parameters (unit size, conical angle, spouting gas-inlet diameter) and operational conditions (p...
Separation of silkworm proteins in cocoon cooking wastewaters via nanofiltration: Effect of solution pH on enrichment of sericin ÇAPAR, GÖKŞEN (2012-02-01) Cocoon cooking wastewater contains waste silkworm proteins including sericin, which is a valuable raw material for many industries including cosmetics and pharmaceuticals. Sericin can be recovered via nanofiltration (NF) with high efficiency; however the process conditions need to be optimized to maximize separation. In this study, the effect of solution pH on NF performance was investigated for separation of silkworm proteins towards sericin enrichment. Solution pH (3.5-9.0) slightly influenced sericin rej...
Preparation and characterization of biodegradable composite systems as hard tissue supports: bone fillers, bone regeneration membranes and scaffolds Sezer, Ümran Aydemir; Hasırcı, Nesrin; Department of Biomedical Engineering (2012) In tissue engineering applications, use of biodegradable and biocompatible materials are essential. As the tissue regenerate itself on the material surface, the material degrades with enzymatic or hydrolytic reactions. After a certain time, natural tissue takes the place of the artificial support. Poly(ε-caprolactone) (PCL) is one of the preferable polymers used in the restoration of the bone defects due to its desirable mechanical properties and biocompatibility. Addition of inorganic calcium phosphate par...
Recovery of caustic from mercerizing wastewaters of a denim textile mill Varol, Cihangir; UZAL, NİĞMET; Dilek, Filiz Bengü; KİTİŞ, Mehmet; Yetiş, Ülkü (2015-03-20) The objective of this study was to evaluate caustic recovery from mercerizing wastewater originating from a denim textile producing plant using membrane technology. For this purpose, ultrafiltration (UF) and nanofiltration (NF) processes were considered. In the first stage, in an attempt to control the possible membrane fouling, pretreatment alternatives of flocculation, centrifugation, and microfiltration were evaluated. These pretreatment application alternatives were unsuccessful as they did not provide ...
