The removal of trace organics by a membrane bioreactor-granular activated carbon (MBR-GAC) integrated system were investigated. The results confirmed that MBR treatment can be effective for the removal of hydrophobic (log D>3.2) and readily biodegradable trace organics. The data also highlighted the limitation of MBR in removing hydrophilic and persistent compounds (e.g. carbamazepine, diclofen...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

Abstract Biobarrier combines the adsorption and biodegradation processes which are carried out simultaneously. This method can increase rate of contaminant reduction, reduce toxicity extend life activated carbon. study aims to evaluate characteristics benzene toluene on granular carbon (GAC). The ratio in expanded bed fixed determines operating conditions process experiment. results showed that...

A number of studies have achieved the consensus that microwave thermal technology can regenerate the granular activated carbon (GAC) more efficiently and energy-conservatively than other technologies. In particular, in the microwave heating industry, permittivity is a crucial parameter. This paper developed two equivalent models to establish the relationship between effective complex permittivi...

Free ammonium in industries wastewater could be one of the worst toxic contaminants of aquatic life if diluted in water. Biological nitrogen removal (BNR) is the most common method for removing ammonium and nitrate from wastewater. Attached growth and suspended growth are the main BNR systems. The aim of the present work was to study the treatment of petrochemical wastewater (ammonium and nitra...

Thermal treatment is routinely used to reactivate the spent granular activated carbon (GAC) from water purification facilities. It also an integral part of sewage sludge and municipal solid waste management. This study presents a detailed investigation fate per- polyfluoroalkyl substances (PFAS) one PFAS alternative (GenX) in thermal processes, focusing on effect GAC. We demonstrate that thermo...

The present work deals with the removal of Metribuzin from aqueous solutions in a batch and continuous mode using electrosorption technique. This technique is based on the combination of two processes: the adsorption of Metribuzin into activated granular carbon (GAC) column and the application of the electrochemical potential. The effects of various experimental parameters (electrochemical pote...

The purpose of this study was to collect experimental data and develop a mathematical model describing the equilibrium phase distribution of a common organic chemical, trichloroethylene (TCE), among cyclodextrin (CD), water, and granular-activated carbon (GAC). Batch tests and a modified linear regression model were applied to assess the partitioning behavior in this multiphase (CD pseudophase–...

Little is known about the effect of carbon-based conductive material (CM) addition on anaerobic co-digestion fat, oil and grease (FOG) waste activated sludge (WAS). In this study, three types CMs (nano-graphite (NG), granular carbon (GAC), cloth (CC)) nine dosages were evaluated for their influences performance. The best dosage was achieved at 0.2 g/L NG, 10 GAC, 1 cm × 5 CC with 13–22% increme...
