[ 1 ] - Comparing Fenton Oxidation with Conventional Coagulation Process for RR198 Dye Removal from Aqueous Solutions
Background and objective: The wastewater discharged from textile industries is one of the main environmental pollutants that causes many problems for the environment if it is not treated or discharged. The present study compared Fenton oxidation process with coagulation and flocculation using the natural coagulant of Sodium Alginate in order to remove Reactive Red 198 Dye. Materials and method...
[ 2 ] - Efficiency of Microalgae Scenedesmus in the Removal of Nitrogen from Municipal Wastewaters
Background: Due to the high content of nitrogen in the municipal wastewaters, this study evaluated the efficiency of Scenedesmus as an important microalgae in the removal of nitrate from wastewaters and its application as an appropriate culture medium. As algae have high resistance to temperature and pH changes, they can absorb low concentrations of nutrients and need simple low-cost technolog...
[ 3 ] - Investigation of Electro-coagulation Process for Phosphate and Nitrate Removal from Sugarcane Wastewaters
Background: Highly-concentrated phosphate and nitrate anions from sugarcane wastewater are often discharged into public waters without standardized treatments. This study assessed the effects of electrical coagulation, initial pH and reaction time in the removal of phosphate and nitrate pollutants. Methods: We used aluminum electrodes to remove the pollutants at Hakhim Farabi Agricultural and ...
[ 4 ] - Assessment Optimization of Safety and Health Risks Using Fuzzy TOPSIS Technique (Case Study: Construction Sites in the South of Iran)
Introduction: Safety and health risk assessment in industries is associated with uncertainties due to the variables affecting it. Therefore, in this research, optimizing safety and health risk assessment was investigated in construction sites by combining a multi-criteria decision-making technique (TOPSIS) and a fuzzy system. In the present study, to answer this question, a new method was used ...
