Introduction: Production and processing of raisin different areas are different based on weather conditions and their technological devices. Thus, generated wastewaters in each area are very different from another one in terms of quality and quantity. The objective of this study was to investigate the efficiency of the electrochemical process, which is an environmentally benign and simple techn...

The aim of this study was to characterize landfill leachate of Çorlu that was heavily industrialized, and to examine the application of coagulation-flocculation and adsorption for the treatment of this leachate. This deposited area is non-regulated and municipal and industrial wastes are deposited uncontrollably. The experiments were conducted to investigate the combined process of coagulation-...

Background and purpose: Textile dye effluents have some potential risks which require effective treatment before discharging into the environment. Advanced oxidation processes can remove pollutants faster than other processes due to active hydroxyl radical production; therefore, increase the efficiency of dye removal. This study was aimed at investigating dye removal process using UVA/ZnO and U...

Introduction: Color is one of the indices of water pollution. Discharge of colored effluent can damage to receiving water resources. One of the proposed methods for treating dyeing wastewater is electrocoagulation process. In this study, decolorization of the real textile effluent by electrocoagulation process using monopolar iron electrodes was studied. Methods: This study was run experiment...
