Adsorption-Enhanced Ceramic Membrane Filtration Using Fenton Oxidation for Advanced Treatment of Refinery Wastewater: Treatment Efficiency and Membrane-Fouling Control

With the development of refining industry, treatment refinery wastewater has become an urgent problem. In this study, a ceramic membrane (CM) was combined with Fenton-activated carbon (AC) adsorption to dispose wastewater. The effect process analyzed using excitation–emission matrix (EEM), ultraviolet-visible (UV-vis) and Fourier transform infrared spectroscopies (FTIR). Compared direct filtration, could significantly improve removal organic pollution, where rate COD TOC be 70% turbidity above 97%. It found that effluent meet local standards. fouling for impact pretreatment on direction. results showed Fenton-AC absorption effectively alleviate fouling. optimal critical flux increased from 60 82 L/(m2·h) compared filtration. After running about 20 d, remained at 55 membrane-fouling resistance only 1.2 × 1012 m−1. Hermia model revealed cake filtration present in early stages process. These great use improving efficiency operation cycle
