Aerobic thermophilic bacteria enhance biogas production
The enhancing effect of aerobic thermophilic (AT) bacteria on the production of biogas from anaerobically digested sewage sludge (methanogenic sludge) was investigated. Sewage sludge (5%, w/w) was incubated at 65°C with shaking for a few months to prepare the AT seed sludge. AT sludge was prepared by incubation of the AT seed sludge (5%, v/v) and sewage sludge (5%, w/w) at 65°C with shaking. The ...

Where To Find Money In Biogas
On the surface, wastewater treatment operations don’t appear to be handling precious material. But these facilities are actually processing a great deal of value every day. Sludge, a byproduct of wastewater treatment, turns out to be an entity worth cherishing. “Depending on treated sludge quality, the final product can be land applied, landfilled, incinerated, or composed,” ...

Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge
Thermal steam-explosion is the most extended hydrolysis pretreatment to enhance anaerobic digestion of sludge. Thermal hydrolysis key parameters are temperature (T) and time (t), and the generally accepted values reported from full-scale information are: 150–230 °C and 20–60 min. This study assesses the influence of different temperature–time–flash combinations (110–180 °C, 5–60 min, 1–3 ...

Novel anaerobic digestion process with sludge ozonation for economically feasible power production from biogas
A novel process scheme was developed to achieve economically feasible energy recovery from anaerobic digestion. The new process scheme employs a hybrid configuration of mesophilic and thermophilic anaerobic digestion with sludge ozonation: the ozonated sludge is first degraded in a thermophilic digester and then further degraded in a mesophilic digester. In small-scale pilot experiments of the ...

Biogas Treatment in WWTP
Wastewater treatment plants (WWTPs) are facilities that consume large amounts of energy (thermal and electrical), as a result of their operation, they produce large amounts of sludge. The anaerobic digestion of these sludges from wastewater treatment produces biogas, which, due to its concentration in methane (CH 4 ), constitutes a biofuel that can be used for energy production. The best ...

Using biogas for combined heat and power
An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs of the installation. However, the engine is integral to the plant, and is the key component in the production of renewable electricity, hence the ...
