Pyrolyzing biosolids can decrease volume and increase value of solids while anaerobic digestion gas liquids from the process could overall methane production. Prediction behavior biogas yield through simulation is valuable when considering new substrates for digestion. In this study, pyrolysis were implemented in Anaerobic Digestion Model No 1 (ADM1) together with a stream thermally hydrolyzed ...

This paper investigates the catalytic hydrogenolysis of solid digestate from anaerobic digestion to extract biofuel.

A Mathematical Model of Anaerobic Digestion with Syntrophic Relationship, Substrate Inhibition, and Distinct Removal Rates

Olive mill solid waste (OMSW) is a pollutant waste coming from olive oil elaboration by the two-phase centrifugation system. OMSW has a high organic matter content and unbalanced carbon to nitrogen (C/N) ratio, 31/1, which avoids obtaining high methane yields in the anaerobic digestion of this waste. In the present study a microalgae, Dunaliella salina, was employed as co-substrate for the OMSW...

Anaerobic digestion is an attractive method for waste stabilization with the potential generation of biogas and stabilized waste residue. Development of a treatment process at short digestion period with maximum process efficiency is the objective of this research. This paper presents the optimization performance between the combined anaerobic digestion and sequential staging concept in thermop...

Anaerobic digestion is a widely employed technique that converts waste into biogas, which can be as renewable energy. To improve its efficiency, but also to treat recalcitrant waste, mixes involving several types of feedstock with different biodegradability rates are fed the process. Finding proper mix difficult and involves extensive, long-lasting experimental work. This paper presents an appr...

Anaerobic degradation of wild halophytes (Kalidium caspicum, Salicornia europaea and Climacoptera lanata) from solonchaks of Kyzylkum desert in comparison with conventional glycophyte Panicum coloratum was studied. Lab-scale reactors were fed with dried and milled plant biomass. Tests were operated under batch and continuous mode at mesophilic (M) and thermophilic (T) temperatures. High concent...

Anaerobic digestion of animal manure in biogas digesters has shown promise as a technology in reducing the microbial load to safe and recommended levels. We sought to treat dairy manure obtained from the Fort Hare Dairy Farm by investigating the survival rates of bacterial pathogens, through a total viable plate count method, before, during and after mesophilic anaerobic digestion. Different mi...

The biological stabilisation of the organic fraction of municipal solid waste (OFMSW) into a form stable enough for land application can be achieved via aerobic or anaerobic treatments. To investigate the rates of degradation (e.g. via electron equivalents removed, or via carbon emitted) of aerobic and anaerobic treatment, OFMSW samples were exposed to computer controlled laboratory-scale aerob...
