this paper presents the adsorption of phenol on granular activated carbon (gac) from nutrient medium suitable for roorganisms’ growth and also the subsequent biodegradation. two parameter langmuir and freundlich adsorption isotherm models were studied using large range of phenol concentration (50-1000 mg/l). in low range of phenol concentration (50-300 mg/l), correlation coefficient, normaliz...

The use of granule activated carbon (GAC) and rubber particles as the bio-fouling reducer in a membrane bioreactor (MBR) was evaluated this study. addition GAC tends to temporarily reduce Transmembrane Pressure (TMP). Then, after initial reduction, TMP gradually increased back up 0.7 bar, indicating significant fouling on membrane. Low values were observed adding 0.5% (V/V) same MBR. organic co...

Multiple anodes can significantly enhance the treatment potential of constructed wetlands coupled with a microbial fuel cell (CW-MFC) system, which has not yet been explored. Thus, present study evaluates multi-anodes and single cathode-based CW-MFC at higher organic loading rates for performance bioelectricity generation. For this purpose, two identical but different materials, i.e., graphite ...

In this study, a low-cost granular activated carbon doped with Fe2O3 nanoparticles (Fe–GAC) was prepared via modified sol-gel technique and utilized for the elimination of lead (Pb(II)) chromium (Cr(T)) ions from synthetic actual brackish water. The effect adsorption parameters on removal Pb(II) Cr(T) water evaluated in batch tests. characterization results validated distribution well-defined o...

Granular activated carbon (GAC) was synthesized from Silver berry (Elaeagnus Angustifolia L.) seeds using zinc chloride as the activation agent. To optimize operating parameters, effects of time and temperature carbonization, impregnation ratio, heating rate on iodine number yield were studied. Optimized parameters ratio 1:1, carbonization 500 °C, 1 hour, 5 °C/min. The GAC under optimized condi...

The biofilm community structure in a granular activated carbon (GAC) filter was investigated by ribosomal intergenic spacer region analysis (RISA). The results showed that microbial diversity diminished and stabilized with time of filter operation. One bacterium (Hydrogenophaga palleronii) was identified according to its 16S-rRNA sequence. However, this bacterium did not degrade any of the HAAs...

Abstract Novel cost-effective catalyst granular activated carbon (GAC)-based zinc ferro nanocomposites for the heterogeneous Fenton's oxidation of dye were synthesized using bioleached laterite iron (BLFe) as a precursor and Psidium gujava leaf extract. Synthesized characterized SEM, EDS, XRD BET surface area analysis. The degradation Rhodamine was carried out with adsorption–Fenton's process. ...

Traces of active pharmaceutical ingredients (APIs) and other chemicals are demonstrated in effluents from sewage treatment plants (STPs) and they may affect quality of surface water and eventually drinking water. Treatment of effluents with granular activated carbon (GAC) or ozone to improve removal of APIs and other contaminants was evaluated at two Swedish STPs, Käppala and Uppsala (88 and 10...

A microbial fluidized electrode electrolysis cell (MFEEC) was used to enhance hydrogen gas production from dissolved organic matter. Flowable granular activated carbon (GAC) particles were used to provide additional surface area for growth of exoelectrogenic bacteria. The use of this exoelectrogenic biofilm on the GAC particles with fluidization produced higher current densities and hydrogen ga...
