However, sustainable management of the concentrate (ROC) is challenging, due to the need for treatment and\/or disposal. The objective of this research was to investigate the efficiency of homogeneous and heterogeneous Fenton-like oxidation processes in removing propoxur (PR), a micro-pollutant compound, from synthetic ROC solution in a submerged ceramic membrane reactor operated in a continuous mode. A freshly prepared amorphous heterogeneous catalyst was synthesized and characterized, revealing a layered porous structure of 5\u201316 nm nanoparticles that formed aggregates (33\u201349 \u03bcm) known as ferrihydrite (Fh). The membrane exhibited a rejection of &amp;gt;99.6% for Fh. The homogeneous catalysis (Fe3+) exhibited better catalytic activity than the Fh in terms of PR removal efficiencies. However, by increasing the H2O2 and Fh concentrations at a constant molar ratio, the PR oxidation efficiencies were equal to those catalyzed by the Fe3+. The ionic composition of the ROC solution had an inhibitory effect on the PR oxidation, whereas increased residence time improved it up to 87% at a residence time of 88 min. Overall, the study highlights the potential of heterogeneous Fenton-like processes catalyzed by Fh in a continuous mode of operation.<\/jats:p>","DOI":"10.2166\/wst.2023.160","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T13:14:22Z","timestamp":1684502062000},"page":"2890-2904","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":4,"title":["Competitive
