Stimulation of methanogenesis in a laboratory scale UASB reactor treating domestic sewage by Fe(0) application.
The effects of application of zero valence Fe (Fe(0)) on the anaerobic digestion of sewage was investigated using two laboratory scale UASB reactors. One reactor had Fe(0) addition in a container found midway along the recycling loop. The other one was a control reactor. In a test run period of 76 days, the Fe(0) application significantly increased the CH, yield by 8.7% and decreased the efflue...
متن کاملThe effect of sludge recirculation rate on a UASB-digester treating domestic sewage at 15 °C.
The anaerobic treatment of low strength domestic sewage at low temperature is an attractive and important topic at present. The upflow anaerobic sludge bed (UASB)-digester system is one of the anaerobic systems to challenge low temperature and concentrations. The effect of sludge recirculation rate on a UASB-digester system treating domestic sewage at 15 °C was studied in this research. A sludg...
متن کاملDynamic Performance of UASB Reactor Treating Municipal Wastewater
The simultaneous dynamic equations for substrate and biomass mass were used to assess the UASB reactor performance of municipal wastewater. The dynamic model equations were solved by using a m.file in MATLAB2011a command window and dynamic equations for substrate and biomass. The objectives of this paper are (1) To develop a simple CSTR model for simulation of UASB reactors performance assuming...
متن کاملThe Emerging Politics of DHS Fusion Centers
This article explores public concerns about the US Department of Homeland Security’s data ‘fusion centers’. These centers, which are proliferating across all US states, coordinate data-sharing among state and local police, intelligence agencies, and private companies. The primary goal of fusion centers is to engage in intelligence-sharing for counter-terrorism purposes. However, they have been ...
متن کاملSyntrophic propionate degradation response to temperature decrease and microbial community shift in an UASB reactor.
Propionate is an important intermediate product during the methane fermentation of organic matter, and its degradation is crucial for maintaining the performance of an anaerobic digester. In order to understand the effect of temperature on propionate degradation, an upflow anaerobic sludge blanket (UASB) reactor with synthetic wastewater containing propionate as a sole carbon source was introdu...
