A general mathematical model that predicts the flow fields in a mixed-flow anaerobic digester was developed. In this model, the liquid manure was assumed to be a non-Newtonian fluid, and the flow governed by the continuity, momentum, and k-epsilon standard turbulence equations, and non-Newtonian power law model. The commercial computational fluid dynamics (CFD) software, Fluent, was applied to ...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
An enzyme-linked immunosorbent assay was developed for the detection of whole cells of methanogens in samples from anaerobic continuously stirred tank digesters treating slurries of solid waste. The assay was found to allow for quantitative analysis of the most important groups of methanogens in samples from anaerobic digesters in a reproducible manner. Polyclonal antisera against eight strains...
The wastewater generated from pharmaceutical industry generally contain high organic load and the treatment is primarily carried out using two major types of biological methods; aerobic and anaerobic. However, due to high strength, it is infeasible to treat some pharmaceutical wastewater using aerobic biological processes. As an alternative, an anaerobic process is preferred to remove high stre...
Bioelectrochemical systems (BESs) can be integrated in situ into anaerobic digesters for increasing methane (CH 4 ) content of biogas. Using BES ex improving biogas quality has recently been gaining attention. However, information on the process under thermophilic conditions is very limited. In this study, we placed a cathode in-line at exit gas from digester to convert carbon dioxide (CO 2 CH ...
Background & Objectives: Listeria bacterium resists to the sludge digestion conditions and Listeria monocytogenes is the most important of them. Sludge produced in the north Isfahan wastewater treatment plant is stabilized by anaerobic digesters and is used for fertilizing agricultural lands after drying in the sludge drying beds. Based on the importance of the subject, the objective of this st...
Background: PCE is a chlorinated aliphatic hydrocarbon which has been used in some industries. Industrial wastewaters polluted with PCE must be treated because of its possible carcinogenic effects. The aim of this study was to determine the PCE biodegradation potential in high concentration using Anaerobic Migrating Blanket Reactor (AMBR) that thus far has not been used for biodegradation of th...
the images of muslims in media, literature and politics have been mostly black and white portrayals of a people alien to modernity, civilization, rationality and pluralism. since the end of the cold war and the onset of deadly terrorist attacks in different areas of the world, especially in the united states, these representations show a palpable difference: muslims are represented not only as ...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
