Anaerobic co-digestion has been widely investigated, but there is limited analysis of interaction between substrates. The objective of this work was to assess the role of carbohydrates, protein and lipids in co-digestion behaviour separately, and together. Two sets of batch tests were done, each set consisting of the mono-digestion of three substrates, and the co-digestion of seven mixtures. Th...

In this study duckweed (Lemna gibba) and waste activated sludge (WAS) were co-digested in different proportions with acclimatized anaerobic granular sludge (AAGS) in mesophilic conditions. The aim was to evaluate if the co-digestion could lead to an increased efficiency of methane production compared to digestion of waste activated sludge alone. Results indicate that co-digestion with both duck...

Cow dung is generally used as the feedstock material for anaerobic digestion to produce biogas. A selection of alternate biomass needed reduce consumption or eliminate use cow dung. Recently, cottonseed hull has been considered primary substrate In this paper, effect biogas production on co-digestion CD with pre-treated CSH using sulfuric acid, hydrochloric hydrogen per oxide, and acetic acid i...

this study investigated the effect of loading and temperature on anaerobic co-digestion of poultry manure with straw in mesophilic conditions. the study was made at lab-scale using 70l reactor with a hrt of 15 days. during the first phase, different loads of 1.0, 2.0, 2.5, 3.0, 3.5 and 4.0 kg vs/m3.d were studied in order to produce biogas. at load of 3.0 kg vs/ m3.d, vs removal and gas product...

The processes of anaerobic digestion and co-digestion are complicated and the development of computational models that are capable of simulation and prediction of anaerobic digester performances can assist in the operation of the anaerobic digestion processes and the optimization for methane production. The artificial neural network approach is considered to be an appropriate and uncomplicated ...

The potential improvement in methane recovery and reaction kinetics from different mixes of potato peel (PP) pig manure (PM) a single stage anaerobic co-digestion/mono-digestion process was investigated laboratory study. highest yield 231 mL/g TCOD added observed the 50:50 mix manure. Compared to mono-digested substrates, co-digestion PP PM at 75:25, 50:50, 25:75 synergistically improved by 17%...

The effects of ultrasonic and thermo-chemical pre-treatments on the methane production potential of anaerobic co-digestion with synthetic kitchen waste (KW) or fat, oil and grease (FOG) were investigated. Non-linear regressions were fitted to accurately assess and compare the methane production from co-digestion under the various pre-treatment conditions and to achieve representative simulation...

Anaerobic co-digestion of residues from the cold pressing and trans-esterification of oilseed rape (OSR) with other farm wastes was considered as a means of enhancing the sustainability of on-farm biodiesel production. The study verified the process energy yields using biochemical methane potential (BMP) tests and semi-continuous digestion trials. The results indicated that high proportions of ...

A search for alternatives economically viable and environmentally sound to the world energy demand, stimulated research in field of anaerobic digestion, as a form renewable co-digestion is an alternative use different types residues, including food wastes. Therefore, this article presents analysis scientific advances realized period 2015 2018 terms co-digestion, with emphasis on especially frui...
