Purpose: To present a techno-economical study of a possible thermophylic anaerobic biological degradation unit installation in Attica, which will manage 35600ton/y of fresh substrate of the source sorted organic fraction of solid municipal waste (SS-OFSMW). Methods: The anaerobic digestion unit consists of a pre-processing step (screening with hands-cutting) and the main dry anaerobic biologica...

Stationary-phase (SP) batch cultures of Saccharomyces cerevisiae, in which growth has been arrested by carbon-source depletion, are widely applied to study chronological lifespan, quiescence and SP-associated robustness. Based on this type of experiments, typically performed under aerobic conditions, several roles of oxygen in aging have been proposed. However, SP in anaerobic yeast cultures ha...

The operation of an activated sludge process at a paper mill (AIPM) in Hedera, Israel, was often characterized by disturbances. As part of a research and development project, a study on new biological treatment was initiated. The study included the operation of three pilot units: a. anaerobic treatment by upflow anaerobic sludge blanket (UASB); b. aerobic treatment by two pilot units including ...

anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

the effect of organic loading rate (olr) provided by hydraulic retention time (hrt) and influent chemical oxygen demand (codin) on the performance of an up-flow anaerobic sludge fixed film (uasff) bioreactor treating palm oil mill effluent (pome) was studied. anaerobic digestion of pome was modeled and analyzed with two variables i.e. hrt and codin. experiments were conducted based on a general...

A continuous compact membrane bioreactor consisted of ceramic-supported graphene oxide (CSGoM) was implemented for the first time anaerobic biodecolorization monoazo Acid Orange 7 (AO7), diazo Reactive Black 5 (RB5), and triazo Direct Blue 71 (DB71) solutions, showing excellent decolorization potential. The prepared by vacuum filtration various solutions using a UF ceramic flat element. efficie...

The innovative and recently discovered n-damo process, based on anaerobic methane oxidation with nitrite, was developed in a membrane-based bioreactor evaluated terms of organic micropollutants (OMPs) removal. main singularity this study consisted the evaluation removal biological reactor. A strategy consisting progressively increasing nitrogen loading rate order to increase specific denitrific...

Experimental studies of two-phase anaerobic digestion corn steep liquor in semi-continuous automatic and semi-automatic modes operation a cascade two bioreactors with monitoring control systems were performed. Corn liquor—a waste product from the process treating grain for starch extraction—was used as substrate simultaneous hydrogen methane production. The daily yields biohydrogen bioreactor 1...

The effect of high organic liquid wastes on the overall performance of anaerobic bioreactor landfills is not known. In this study three different liquid wastes were added to mix of office paper, newspaper, cardboard and plastic in 3 different concentrations under anaerobic conditions to determine their effect on degradation of organics. The addition of buffer chemicals was found to improve degr...
