Fouling Analysis for Different UF Membranes in Reactive Dyeing Wastewater Treatment ZAF, RUKEN DİLARA; Oruc, B. Kocer; Erkanlı, Mert; Yılmaz, Levent; Yetiş, Ülkü; Culfaz-Emecen, Z. (2017-05-24) 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 UF membranes (5 kDa PES (polyethersulfone), 5 kDa and 1 kDa RC (regenerated cellulose), 2 kDa TFC (thin film composite) and 3,5 kDa polypiperazine-amide) were compared based on color (as absorbance at wavelengths of 436, 525 and 620 nm) and TOC treatment efficiency, permeate flux and fouli...
Fouling analysis for different ultrafiltration membranes in reactive dyeing wastewater treatment Zaf, Ruken Dilara; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Department of Environmental Engineering (2017) Textile industry produces wastewater that is often very rich in salt and color, containing residues of dyes and other chemicals. Treating this wastewater to exceptionally high quality standards, typically for reuse purposes, necessitates advanced treatment methods among which membrane technology is a leading one. However, membrane fouling which can be caused by dissolved and particulate solids appears as the major limitation with the use of membranes in wastewater reclamation that leads to reduced efficienc...
Fouling behavior of microstructured hollow fiber membranes in dead-end filtrations: Critical flux determination and NMR imaging of particle deposition Çulfaz Emecen, Pınar Zeynep; Utiu, Lavinia; Kueppers, Markus; Bluemich, Bernhard; Melin, Thomas; Wessling, Matthias; Lammertink, Rob G. H. (2011-03-01) The fouling behavior of microstructured hollow fibers was investigated in constant flux filtrations of colloidal silica and sodium alginate. It was observed that the fouling resistance increases faster with structured fibers than with round fibers. Reversibility of structured fibers' fouling was similar during silica filtrations and better in sodium alginate filtrations when compared with round fibers. The deposition of two different silica sols on the membranes was observed by NMR imaging. The sols had dif...
Fouling behavior of microstructured hollow fibers in cross-flow filtrations: Critical flux determination and direct visual observation of particle deposition Çulfaz Emecen, Pınar Zeynep; Wessling, M.; Lammertink, R.G.H. (Elsevier BV, 2011-04-15) The fouling behavior of microstructured hollow fiber membranes was investigated in cross-flow filtrations of colloidal silica and yeast. In addition to the as-fabricated microstructured fibers, twisted fibers made by twisting the microstructured fibers around their own axes were tested and compared to round fibers. In silica filtrations, the three different fibers showed similar behavior and increasing Reynolds number increased the critical fluxes significantly. In yeast filtrations, the twisted fiber perfo...
Fouling behavior of microstructured hollow fiber membranes in submerged and aerated filtrations Çulfaz Emecen, Pınar Zeynep; Lammertink, R.G.H. (2011-02-01) The performance of microstructured hollow fiber membranes in submerged and aerated systems was investigated using colloidal silica as a model foulant. The microstructured fibers were compared to round fibers and to twisted microstructured fibers in flux-stepping experiments. The fouling resistances in the structured fibers were found to be higher than those of round fibers. This was attributed to stagnant zones in the grooves of the structured fibers. As the bubble sizes were larger than the size of the gro...
