[ 1 ] - Efficiency of Electrocoagulation, Sedimentation and Filtration Hybrid Process in Removing Chemical Oxygen Demand and Turbidity from Carwash Industrial Wastewater: Optimization by Response Surface Methodology

Background and purpose: Nowadays, rapid growth of car wash industries has led to a demand for wastewater reclamation. In this study, the hybrid process including electrocoagulation/flotation, sedimentation, and filtration were used in treatment of real carwash wastewater. Materials and methods: In this research, the sample was first entered into the ECF reactor, then entered the retention tank...

[ 2 ] - Chromium removal and water recycling from electroplating wastewater through direct osmosis: Modeling and optimization by response surface methodology

Background: Considering the carcinogenic effects of heavy metals, such as chromium, it is essential to remove these elements from water and wastewater. Direct osmosis is a new membrane technology, which can be a proper alternative to conventional chromium removal processes. Methods: The wastewater samples were collected from an electroplating unit, located in Alborz industrial city, Qazvin, Ir...
