| الوصف: | Effective wastewater treatment is a key aspect in safeguarding a healthy aqueous environment, however many treatment technologies have limitations of either cost or generation of additional waste, which ends up further polluting the environment. Hence, this work focuses on the deployment of iron mediated processes, such as photo-Fenton oxidation, for wastewater treatment and seeks to provide environmentally sustainable solutions to technical challenges associated with these processes. Challenges in the application of photo-Fenton process include the (a) high energy consumption and generation of environmental impacts attributed to the use of artificial UV irradiation during treatment, (b) reduction of the efficiency of the process due to the formation of fouling on quartz sleeves, and (c) depletion of natural resources because of the need to add iron in the wastewater to initiate the Fenton reaction. To address these challenges the following solutions were explored. First, a solar photo-Fenton process based on a circular economy concept was developed as to minimise the use of energy and chemicals addition in the wastewater. For this purpose, acid mine drainage (AMD), which is very acidic pH˂3 and rich in iron, was used to deliver iron catalyst in the Fenton/photo-Fenton treatment process for the treatment of municipal wastewater. At the best conditions assayed, it was observed that COD removal reached 99% after 90 min of photo-Fenton treatment under simulated solar light in the presence of 30 mg/L Fe. The removal efficiency of the treatment system indicated that this circular economy concept can be very promising and should be considered for wastewater treatment on large-scale. Secondly, lab-scale experiments were performed to further understand the effect of basic operating parameters on the formation of quartz fouling during the photo-Fenton treatment of municipal wastewater. It was observed that fouling formation was higher in phosphorous-rich followed by iron-rich wastewater. At the same time 30% and 59% COD ... |
