Generalised modelling approach for anaerobic co-digestion of fermentable substrates
Bioresource Technology, 2013A general methodology to implement fermentable soluble substrates in the IWA Anaerobic Digestion Model No. 1 (ADM1) that extends its application to anaerobic co-digestion of multiple substrates is presented. The approach considers the fermentation of new soluble substrates, not originally described in ADM1, as channelled through mass- and electron ...

Thermophilic anaerobic co-digestion of poultry litter and thin stillage
Bioresource Technology, 2013The purpose of this study was to test whether the performance of a thermophilic CSTR digester that has been stabilized on poultry litter will be enhanced or diminished by the addition of thin stillage as co-substrate. Replicate laboratory digesters, derived from a stable pilot-scale digester, were operated with increasing ratios (w/w) of thin stillage ...

Anaerobic co-digestion of different wastes in a UASB reactor
Waste Management, 2018Anaerobic co-digestion has made a greater impact on the biogas production from mixing different type of waste. In this research, sewage sludge (SS) and cow manure (CM), was used as a primary waste along with kitchen waste (KW), yard waste (YW), floral waste (FW) and dairy wastewater (DWW) as co-substrate for anaerobic digestion.

The anaerobic co-digestion of food waste and cattle manure
Bioresource Technology, 2013This study assessed the anaerobic co-digestion of food waste and cattle manure, in order to identify the key parameters that determine the biogas and methane yield. Results of both batch and semi-continuous tests indicated that the total methane production is enhanced in co-digestion, with an optimum food waste (FM) to cattle manure (CM) ratio of 2. At

Anaerobic batch co-digestion of sisal pulp and fish wastes
Bioresource Technology, 2004Co-digestion of various wastes has been shown to improve the digestibility of the materials and biogas yield. Batchwise digestion of sisal pulp and fish waste was studied both with the wastes separately and with mixtures in various proportions. While the highest methane yields from sisal pulp and fish waste alone were 0.32 and 0.39 m3 CH4/kg volatile ...

Anaerobic co-digestion of dairy cattle manure and pear waste
Bioresource Technology, 2014Anaerobic co-digestion of pre-treated dairy cattle manure (LCM) with pear waste after a storage period (PLF) was tested at four inclusion levels: 0%, 25%, 75% and 100%. Inclusion levels consisted in the replacement of the volatile solids (VS) from the LCM with the VS from PLF keeping the organic loading rate around 1.1 ± 0.4 g SVL(-1)d(-1).

Evaluation of parameters for monitoring an anaerobic co-digestion process
Applied Microbiology and Biotechnology, 2000The system investigated in this study is an anaerobic digester at a municipal wastewater treatment plant operating on sludge from the wastewater treatment, co-digested with carbohydrate-rich food-processing waste. The digester is run below maximum capacity to prevent overload.

[Anaerobic co-digestion of corn stalk and vermicompost].
Huan jing ke xue= Huanjing kexue, 2011The characteristics of corn stalk digested alone at different total solid (TS) loading rates and co-digestion of various proportions of corn stalk and vermicompost were investigated by batch model at 35 degrees C +/- 1 degrees C. The organic loading rates (OLRs) studied were in the range of 1.2%-6.0% TS and increasing proportions of vermicompost from ...

Microalgae Growth Using High‐Strength Wastewater Followed by Anaerobic Co‐Digestion
Water Environment Research, 2010Integration of algal biofuel production to wastewater anaerobic digestion infrastructure has the potential to increase biogas production, decrease high and variable internal nitrogen loads, and improve sludge digestibility and dewaterability. In this research, two species of microalgae, Spirulina platensis and Chlorella sp., were grown on sludge ...

Anaerobic co-digestion of septage and landfill leachate
Bioresource Technology, 1999Abstract This paper examines the operating parameters and treatment efficiency in digestion of septage with landfill leachate. Four lab-scale CSTR digesters were operated at 35 ± 1°C. Septage and leachate were mixed at the ratio of 1:0, 1:1, 2:1 and 3:1 on the basis of chemical oxygen demand (COD).
