Dark Hydrogen Fermentation From Paper Mill Effluent (PME): The influence of Substrate Concentration and Hydrolysis

Paper mill effluent (PME) was used as an organic feedstock for production of biohydrogen via dark fermentation using heat-shock pretreated anaerobic sludge under mesophilic conditions. The influence of substrate concentration (5, 10 and 15 g-COD/L) and the initial pH (5 and 7) on the efficiency of dark hydrogen fermentation from PME were investigated. The highest hydrogen yield of 55.4 mL/g-COD...

Bioconversion of wheat stalk to hydrogen by dark fermentation: effect of different mixed microflora on hydrogen yield and cellulose solubilisation.

This study determined hydrogen production, volatile fatty acids (VFAs) generation and cellulose solubilisation from anaerobic dark fermentation of wheat stalk and showed the effect of different mixed microflora. The cumulative hydrogen yields of anaerobic digested activated sludge (AS)-inoculated and anaerobic digested dairy manure (DM)-inoculated system were 23.3 and 37.0 mL/g VS at 204 h, res...

Production Of Hydrogen By Wastewater Sludge Using Anaerobic Fermentation In A Pilot Scale Reactor

The aim of this study is to investigate the production of bio-hydrogen, via dark anaerobic fermentation in a pilot scale reactor under batch conditions, using a mixed microflora. As inoculum, anaerobic digested sludge, collected from municipal wastewater treatment plant, was used after being pre-treated with HCl 1N for 24h (pH 3) in order to inhibit the methanogenic bioactivity. As a source of ...

Improvement of Anaerobic Digestion of Sewage Sludge, Using Combined Hydrogen Peroxide and Thermal Pre-Treatment

The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...
