The effective performance of electrocoagulation (EC) technique in the treatment of olive mill wastewater (OMW) was investigated using Al and Fe electrodes. Current densities (CD), electrode materials (Al and Fe), electrolyte amounts, time and initial pH value were selected as parameters. In these parameters, the removal percentage of chemical oxygen demand (COD), color, phenol and lignin from OMW were experimentally investigated. OMW was used directly without pH adjustment and pretreatment. The experiment results show that the removal efficiency depends on time, types of electrodes, applied current and electrolyte amounts and pH value. Optimum working pH was found to be in the range from 3 to 7.

Treatment of olive mill wastewater by different physicochemical methods and utilization of their liquid effluents for biological hydrogen production Eroglu, Ela; Erolu, Inci; Gündüz, Ufuk; Yucel, Meral (2009-04-01) in this study various two-stage processes were investigated for biological hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001. Two-stage processes consist of physicochemical pretreatment of OMW followed by photofermentation for hydrogen production. Explored pretreatment methods were chemical oxidation with ozone and Fenton's reagent, photodegradation by UV radiation, and adsorption with clay or zeolite. Among these different two-stage processes, strong chemical oxidants ...
Removal of cobalt from zinc sulfate solution by cementation prior to zinc electrowinning Kayın, Pınar Burcu; Topkaya, Yavuz Ali; Department of Metallurgical and Materials Engineering (2003) The aim of this study was to investigate the removal of cobalt from zinc sulfate solution by cementation with the help of conventional and new type of additives that were 4% Sn-zinc alloy powder and 10% Sn-zinc alloy powder, respectively. Synthetic leach solutions containing 150 g/l Zn and 75 mg/l Co were prepared and used in all of the experiments. The parameters researched with the conventional method were the amount of arsenic trioxide and the effect of copper sulfate on cementation of cobalt. While usin...
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 ion concentrations were examined. Highest Cr(VI) retention was obtained at a loading of 0.01 at pH 4. Increasing both polymer and chromate concentrations at a fixed loading of 0.01 decreased the retention which demonstrated the effect of crowding. In the presence of competing anions such as ...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019) The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
Effect of iron and molybdenum addition on photofermentative hydrogen production from olive mill wastewater Eroglu, Ela; Gündüz, Ufuk; Yucel, Meral; Eroglu, Inci (2011-05-01) Photofermentative hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001 was assessed under iron and molybdenum supplementation. Control cultures were only grown with 2% OMW containing media. The analysis included measurements of biomass accumulation, hydrogen production, pH variations of the medium, and changes in the chemical oxygen demand (COD) of the wastewater. Growth under control and Mo-supplemented experiments yielded about the same amount of biomass (similar to 0.4 ...
