Evaluating the efficiency of phosphorus removal in aqueous solutions by Fenton Method

Background and Aim: A brief look at the history of wastewater treatment shows that wastewater treatment began in the twentieth century and with the removal of suspended and organic matters from the wastewater. However, with the passage of time and the emergence of inappropriate environmental conditions, experts decided to do to a fuller treatment of the wastewater. Phosphorus is essential for the growth of algae and other living organisms, but due to eutrophication in waters and various complications that it creates, it is known as a severe pollutant. Given the importance of the issue, this research is conducted to evaluate the efficiency of phosphorus removal from aqueous solutions by Fenton method. Materials and Methods: This study is a descriptive study that the removal of phosphorus from aqueous solutions by the Fenton was carried out by preparation of the water solutions. The studied concentrations of phosphorus were in the range of 1-5 mg/l, pH 3-9, contact times 5 to 30 min, and the Fenton ratios in the range of 1:1 and 1:5 and 1:10. The Results: The optimum obtained values of the studied parameters to maximum 80% removal, the phosphorus concentration 3 mg/l, pH = 4, Fenton ratio (H2O2: Fe) =1:5 and the contact time of 20 min. Discussion and Conclusion: According to experiments conducted in this study, it was found that this method is effective in removing phosphorus from aqueous solutions.
