Biomethane production by anaerobic digestion is an efficient technology to treat organic waste and produce clean energy. A growing number of studies has attempted use carbon-based materials enhance methane performance. Granular activated carbon (GAC) commonly used due its low price high efficiency. Moreover, the conductivity GAC favors direct interspecies electron transfer (DIET) coupled with C...

Spectrophotometric measurement applied on saturated granular activated carbon (GAC) is not yet explored. A colorimetric method in the visible range has been developed in order to determine the exhaustion level of GAC used in rum production. Aqueous ammonia solution has been used as an indicative agent to determine the extraction rate of taste compounds within the rum production process and the ...

Activated carbon prepared form coconut residues (CORC), and agricultural waste byproduct obtained after oil extraction was used for the adsorption of Ni(II) form aqueous solution. The process of uptake obeys both Freundlich and Langmuir adsorption isotherms. Kinetic studies indicate that it obeys Lagergram kinetic model. Quantitative removal of Ni(II) from 100mL aqueous solution containing 10mg...

A favorable microenvironment for biofilm growth on GAC particles was shown using green fluorescent protein (GFP) as a marker for a phenol degrading bacterium, Pseudomonas putida F1. The dispersion of P. putida F1 in a biofilm covering granulated activated carbon (GAC) particles was monitored and compared to a biofilm on non-activated granular carbon particles. Laser scanning confocal microscopy...

The SIRIUS-P commercial reactor design produces 1000 MWe and is driven by 60 KrF laser beams. The chamber has an inner radius of 6.5 m and consists of a first wall fabricated from a carbon/carbon composite and a blanket made of SiC. The chamber is cooled by a flowing granular bed of solid ceramic material, TiO2 for the first wall and Li2O for the blanket. The overall tritium breeding ratio is 1...

Perfluorinated compounds (PFCs) consist by a hydrophobic perfluorinated carbon tail and a hydrophilic ionic headgroup. Because of their unique structure, PFCs have a wide variety of applications including active ingredient in fire fighting foams, impregnation for food packing and waterproof breathable fabrics and the producing of teflon. Recently, the research interest for these compounds has b...

Present study is carried out for the removal of As(lII) from water using commonly available adsorbents such as sand, from Yamuna river (Delhi ), as well as from Ganga river (Kolkata), activated carbon, Hametite ore and sand -iron scrap mixture. All these adsorbents are used as received but sand and activated carbon which do not show much adsorption for As(lII) are modified by treating with diff...

Adsorption is a fundamental process in the physicochemical treatment of municipal wastewaters, a treatment which can economically meet today's higher effluent standards and water reuse requirements. Activated carbon is the most effective adsorbent for this application. Expanded-bed contact systems permit most efficient use of granular carbon for waste treatment. The adsorption process is enhanc...
