| Abstract | ||||
| Wastewater treatment is one of the most critical environmental challenges because of the interactions that occur between sewage, soil, water, and human health. If wastewater is disposed of in banks and groundwater reservoirs without proper treatment, there is a serious risk to public health. The interplay of sewage, soil, water, and human health in the environment necessitates the development of efficient wastewater management techniques in order to prevent harmful consequences. Using Fenton technology for wastewater treatment is a great step toward achieving high organic substances, and as a result, the use of sustainable alternatives to treat that wastewater is an innovation in the field of wastewater treatment that will lead to increasing the standards of the water resulting from the treatment process. This study optimized the operating parameters necessary to obtain a greater COD elimination by the establishment of a laboratory experiment based on Fenton technology. The optimal pH value and quantities of peroxide of hydrogen (H2O2) and ferric salt (Fe2+) were calculated using a laboratory model. Fenton technique operates best at the following conditions: PH=4.2, Fe+2= 21.9 mM per liter, H2O2= 335 mM per liter. This allows for COD removal effectiveness of up to 71%, according to a numerical design carried out using Box-Behnken Design. To remove organic debris as efficiently as possible so that it may be used for irrigation, a second experimental model was created by putting a tank of aeration and filter unit next to the Fenton tank. As of right now, the final concentrations of COD, BOD, TSS, TN, and TP were 32.4, 14.9, 27, 12.1, and 1.12 ppm, each. The overall effluent concentrations were less than those allowed by the Egyptian regulation for irrigation reuse. Furthermore, the water may be recycled to irrigate green spaces in newly constructed cities, reducing the need for fresh water, which is becoming increasingly scarce and one of the greatest problems confronting mankind in the twenty-first century. | ||||
