The crucial role of manganese(III) species in the oxidative and catalytic reactivity manganese oxides have been widely reported. However, direct activation radical precursors by Mn(III) is still a matter discussion. In this work, ability Mn(III)-bearing oxide (Mn2O3) for peroxydisulfate (PS) peroxymonosulfate (PMS) was evaluated compared using caffeine (CAF) as model pollutant. Complete CAF rem...

Abstract Treatment of the filter cake layer after drilling is essential for better cement integrity and to retain original reservoir permeability. Compared water-based cake, oil-based mud removal more sophisticated as oil encloses cake’s particles. Therefore, clean-up requires wettability alteration additives (mutual solvents and/or surfactants) permitting acid/filter reaction. With an appropri...

Biofiltration for drinking water treatment has several quality benefits but questions remain about biofilter start-up in temperate climates where temperature and changes can impact performance. A year-long full-scale demonstration was performed with biofilters operated parallel to chlorinated filters (O1) monitor the development of microbiota across acclimation period respect removal Mn total o...

The activated carbon loaded with manganese (GAC-Mn) was prepared and optimized for the treatment of acid red wastewater. Scanning electron microscope-energy dispersive spectrometer (SEM-EDS), Brunner-Emmett-Teller surface area (Sbet) analysis results revealed that successfully on larger specific obtained. kinetics study indicated removal GAC-Mn followed pseudo-second-order model.
