This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for treatment of spiked clopyralid. To do this, remediation tests at lab (3.45 L), bench (175 L) and pilot (1400 scales have been carried out. The PRB selected was made merged particles zero valent iron (ZVI) granular activated carbon (GAC). Results show tha...

Due to its high oil content, the discharge of bilge water from ships is one most important pollutants in marine ecosystem. In this research, we investigated treatment for Haydarpasa Waste Collection Plant by Fenton oxidation followed granular activated carbon (GAC) adsorption. We applied following optimum operational conditions oxidation: [Fe2+]: 6 mM; [H2O2]: 30 and ratio [Fe2+]/[H2O2]: 1/5. A...

The aim of present study was to treat municipal wastewater in two-stage anaerobic fluidized membrane bioreactor (AFMBR) (anaerobic fluidized bed reactor (AFBR) followed by AFMBR) using granular activated carbon (GAC) as carrier medium in both stages. Approximately 95% COD removal efficiency could be obtained when the two-stage AFMBR was operated at total HRT of 5h (2h for AFBR and 3h for AFMBR)...

The present work deals with the study of the adsorption of Trichloroethylene (TCE) onto a commercial granular activated carbon (GAC). Thermodynamic (batch) and dynamic (fixed-bed column) tests were carried out, under a wide range of operating conditions. In particular, adsorption isotherms were preliminary determined to support the investigation on a fixed-bed column at lab-scale. The main flui...

In this paper, components of an industrial wastewater that cause operational problems during biological treatment were oxidized by UV light and hydrogen peroxide (UV/H202). Preoxidation of wastewater was shown to remove polyvinylpyrrolidone (PVP) and ethoxylate surfactant and increase overall biodegradability. Several UV intensities and hydrogen peroxide concentrations were tested to find optim...

Drinking water and groundwater treatment of perfluoroalkyl acids (PFAAs) heavily relies on adsorption-based approaches using carbonaceous materials, such as granular activated carbon (GAC). Application GAC is restricted by its inefficiency to remove short-chain PFAAs that have prevalently emerged substitutes and/or metabolites long-chain polyfluoroalkyl substances (PFAS). Here, we synthesized r...

Pharmaceutically active compounds (PhACs) widely present in urban wastewater effluents pose a threat to ecosystems the receiving aquatic environment. In this work, efficiency of granular activated carbon (GAC) - based catalytic processes, namely wet peroxide oxidation (CWPO), peroxymonosulfate (PMS/GAC) and peroxydisulfate (PDS/GAC) at ambient temperature pressure were studied for removal 22 Ph...

Point-of-use filters containing granular activated carbon (GAC) are an effective method for removing certain chemicals from water, but their ability to remove bacteria and viruses has been relatively untested. Collision efficiencies (alpha) were determined using clean-bed filtration theory for two bacteria (Raoutella terrigena 33257 and Escherichia coli 25922), a bacteriophage (MS2), and latex ...

This study consists of a review on the removal efficiencies wide spectrum micropollutants (MPs) in biological treatment (mainly membrane bioreactor) coupled with activated carbon (AC) (AC added bioreactor or followed by an AC unit, acting as post treatment). It focuses how presence may promote MPs and effects dissolved organic matter (DOM) wastewater. Removal data collected are analysed versus ...
