Removal of dyes and pigments from wastewaters of dying and printing industries is a major environmental issue. Sorption rate and equilibrium parameters of Methylene Blue on granular and powdered activated carbons were investigated in a batch adsorber. Due to the significance of pore diffusion resistance and partial closure of pore mouths by dissociatively chemisorbed dyes, both sorption rate and sorption capacity values evaluated for granular Carbon were lower than the corresponding values for powdered activated carbon. Concentration independent effective pore diffusivity values in the order of magnitude of 10(-9) cm(2)/s were obtained by the moment analysis of a proposed diffusion model (Model I).

Adsorption of reactive yellow 145 onto chitosan coated magnetite nanoparticles Kalkan, Nuzhet Ayca; AKSOY, SERPİL; Aksoy, Eda Ayse; Hasırcı, Nesrin (2012-04-05) Removal of dyes from the industrial discharge water is an important issue for safety of the environment. In this study, magnetic (magnetite, Fe3O4) nanoparticles were coated with chitosan (CS) and the efficiency of these chitosan coated magnetic nanoparticles (Fe3O4-CS) for the adsorption of a reactive textile dye (Reactive Yellow 145, RY145) was examined first time in literature. TEM, XRD, and EPR results revealed that the thickness of the coat was about 25 nm, no phase change in the spinel structure of ma...
Comparison of non-catalytic and catalytic ozonation processes of three different aqueous single dye solutions with respect to powder copper sulfide catalyst Pirgalioglu, Saltuk; Ozbelge, Tuelay A. (2009-07-01) Treatment of textile wastewaters containing dyes has not been very successful by conventional methods such as biological treatment. In order to overcome this problem, ozonation based on the oxidation of organic pollutants has been studied by researchers. Catalytic ozonation and advanced oxidation processes (ACPs) are used in order to increase the efficiency of sole ozonation further. In this work, catalytic ozonation in the presence of copper sulfide (CuS) powder as a catalyst was investigated in the treatm...
Laboratory investigation of the treatment of chromium contaminated groundwater with iron-based permeable reactive barriers Uyuşur, Burcu; Ünlü, Kahraman; Department of Environmental Engineering (2006) Chromium is a common groundwater pollutant originating from industrial processes such as metal plating, leather tanning and pigment manufacturing. Permeable reactive barriers (PRBs) have proven to be viable and cost-effective systems for remediation of chromium contaminated groundwater at many sites. The purpose of this research presented in this thesis is to focus on two parameters that affect the performance of PRB on chromium removal, namely the concentration of reactive media and groundwater flux by ana...
LIFE CYCLE ASSESSMENT OF ACTIVATED CARBON ADSORPTION AND OZONATION TO REMOVE MICROPOLLUTANTS FROM TEXTILE WASTEWATER Akdeniz, Ayşe Sena; Yetiş, Ülkü; Department of Environmental Engineering (2022-8-29) To avoid potential adverse effects by micropollutants in secondary textile wastewater, it is necessary to apply an advanced treatment process, among which activated carbon adsorption and ozone oxidation are the most attractive alternatives. There is still a lack of studies evaluating the environmental impacts of these processes for the tertiary treatment of textile wastewater. Using the life cycle assessment (LCA) methodology, this study assesses and compares the environmental impacts of ozone oxidation and...
Numerical investigation of the viscoelastic fluids Yapıcı, Kerim; Uludağ, Yusuf; Department of Chemical Engineering (2008) Most materials used in many industries such as plastic, food, pharmaceuticals, electronics, dye, etc. exhibit viscoelastic properties under their processing or flow conditions. Due to the elasticity of such materials, deformation-stress in addition to their hydrodynamic behavior differ from simple Newtonian fluids in many important respects. Rod climbing, siphoning, secondary flows are all common examples to how a viscoelastic fluid can exhibit quite distinctive flow behavior than a Newtonian fluid would do...
