چکیده

The supplementation of trace elements (TE’s) is a common practice in biogas production and especially in the mono-fermentation of energy crops and agro-processing wastes. The objective of this work is to give an overview on TE’s in the anaerobic digestion process, to show TE deficiencies in different substrates, and to demonstrate the effects of trace element addition on the increase of the Organic Loading Rate (OLR).

The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors.

The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process inter...

Optimization of Thermophilic Anaerobic Digestion of Winery Bio-waste by Micro-nutrients Augmentation

Thermophilic anaerobic digestion is a suitable technology to treat agricultural waste because of its higher biogas production, hygienisation effect and solids removal efficiency. Although these benefits, poor effluent quality and instability are encountered in some cases. The anaerobic co-digestion of winery waste and waste activated sludge at 55°C, operating at 23 days HRT and with an organic ...

Utilization of Co-digestion of Local Brewery Wastes and Cattle Dung as a Potential Source of Biogas and Organic Fertilizer

Biogas production from co-digestion of local brewery waste (BW) and cow dung (CD) was study for value added to this solid waste. The objective of this research was to fine the optimum condition for maximum biogas production and also examined the effectiveness of the biogas residue (liquor from anaerobic digestion process) as a nitrogen source for the production of okro. The experiments were per...
