Enhanced syntrophic propionate degradation and methane production by granular activated carbon in AnSBR

Experimental and Theoretical Study on the CH4 Adsorption by Granular and Microporous Activated Carbon

Adsorbed natural gas (ANG) by Granular Activated Carbon (GAC) has been widely investigated as an alternative to CNG and LNG technologies for storage and transportation of natural gas. In the present work, a theoretical and experimental study was conducted to accurately determine the amount of adsorption of CH4 by GAC. To carry out the experiments, the volumetric method was used up to 4 MPa at c...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Separation Efficiency of Glucose and Maltose from Industrial Effluent by Granular Activated Carbon

This paper describes the performance of Granular Activated Carbon (GAC) to adsorb and separate glucose and maltose solutes from the industrial effluents by adsorption process. In this study, the capability of Granular Activated Carbon (GAC) to adsorb glucose and maltose were experimentally examined. Commercial GAC (mesh 12-20), supplied by Sigma Aldrich company in...

Response of methane production via propionate oxidation to carboxylated multiwalled carbon nanotubes in paddy soil enrichments

Carboxylated multiwalled carbon nanotubes (MWCNTs-COOH) have become a growing concern in terms of their fate and toxicity in aqueous environments. Methane (CH4) is a major product of organic matter degradation in waterlogged environments. In this study, we determined the effect of MWCNTs-COOH on the production of CH4 from propionate oxidation in paddy soil enrichments. The results showed that t...

Syntrophic propionate degradation response to temperature decrease and microbial community shift in an UASB reactor.

Propionate is an important intermediate product during the methane fermentation of organic matter, and its degradation is crucial for maintaining the performance of an anaerobic digester. In order to understand the effect of temperature on propionate degradation, an upflow anaerobic sludge blanket (UASB) reactor with synthetic wastewater containing propionate as a sole carbon source was introdu...
