Investigating the State of Skin Layer of Asymmetric Polyethersulfone (PES) - Zeolitic Imidazole Framework-8 (ZIF-8) Mixed Matrix Gas Separation Membranes and Its Effect on Gas Separation Performance Tüzün Antepli, Burcu; Yılmaz, Levent; Kalıpçılar, Halil (2022-06-07) © 2022 Wiley-VCH GmbH.Asymmetric and dense polyethersulfone (PES) and PES/ZIF-8 (Zeolitic Imidazole Framework-8) membranes were produced by nonsolvent induced phase inversion and solvent evaporation, respectively. The skin...
Rapid prototyping of cognitive agent simulations using C-BML transformations Topcu, Okan; Yılmaz, Levent (2020-04-01) Simulating battle management is an essential technique used in planning and mission rehearsal as well as training. Simulation development costs tend to be high due to the complexity of cognitive system architectures in suc...
Sulfate removal from drinking water by commercially available nanofiltration membranes: A parametric study Karabacak, Aslı; Dilek, Filiz Bengü; Yılmaz, Levent; KİTİŞ, Mehmet; Yetiş, Ülkü (2020-01-01) © 2020 Desalination Publications. All rights reserved.The efficacy of nanofiltration (NF) in removing sulfate from a high sulfate content (370–460 mg/L) surface water was investigated. NF tests were carried out using a lab...
Preparation and characterization of supported PES membranes TOPUZ, BERNA; Yılmaz, Levent; Kalıpçılar, Halil (Journal of the Faculty of Engineering and Architecture of Gazi University, 2019-01-01) In the present study. polyethersulfone (PES) membranes on a macroporous alumina support was prepared by solvent-deposition method to separate H-2/CH4 mixture. The membrane solution viscosities were determined in order to u...
The Gas Permeation Characteristics of Ternary Component Mixed Matrix Membranes Prepared Using ZIF-8 with a Large Range of Average Particle Size Ayas, Ilhan; Yılmaz, Levent; Kalıpçılar, Halil (2018-11-28) ZIF-8 crystals with average particle sizes of 14, 23, 65, 144, and 262 nm were synthesized to prepare poly(ether sulfone) based mixed matrix membranes with 10 and 20% loading. The membranes were characterized by measuring ...
Dehydration of Industrial Byproduct Solutions for Recycling via Pervaporation-Adsorption Hybrid Process Büküşoğlu, Emre; Kalıpçılar, Halil; Yılmaz, Levent (2018-02-14) Dehydration of used solvents in the printing and packaging industry is required in order to reuse or increase the commercial value of the solvents. In this study, a pervaporation-liquid-phase adsorption hybrid process for ...
Fouling Analysis for Different UF Membranes in Reactive Dyeing Wastewater Treatment Zaf, Ruken Dilara ; Oruc, B. Kocer; Erkanlı, Mert; Yılmaz, Levent; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep (2017-5-24) In this study, different ultrafiltration (UF) membranes are analyzed by means of their fouling characteristics. The aim of the work is pointing the most suitable membrane type for reactive-dying wastewater. Five different ...
Recovery of brackish water from reactive dyeing wastewater by ultrafiltration Erkanlı, Mert; ZAF, RUKEN DİLARA; Yılmaz, Levent; Çulfaz Emecen, Pınar Zeynep; Yetiş, Ülkü (2017-02-06) In this study, brackish water recovery from a real reactive dyeing textile effluent for reuse of water and salt was investigated. With the aim of improving the overall retention of species that are partly retained in a sin...
Recovery and reuse of reactive dyeing wastewater using a sequential ultrafiltration process Erkanlı, Mert; Yılmaz, Levent; Çulfaz Emecen, Pınar Zeynep; Yetiş, Ülkü (null; 2017-02-06)
Removal of hexavalent chromium anions via polymer enhanced ultrafiltration using a fully ionized polyelectrolyte HAKTANIR, CEREN; Ozbelge, H. Onder; Bicak, Niyazi; Yılmaz, Levent (Informa UK Limited, 2017-01-01) A fully ionized polyelectrolyte was synthesized for Cr(VI) removal from aqueous solutions by continuous polymer enhanced ultrafiltration (PEUF). Effect of operating parameters such as pH, loading, polymer, and competing io...
