PROJECT SUMMARY Bacteria capable of exocellular transfer of electrons to solid surfaces, called exoelectrogens, make it possible to obtain electricity from the breakdown of organic matter in microbial fuel cells (MFCs). We obtained several new exoelectrogenic bacteria during this project. We isolated Rhodopseudomonas palustris DX-1, and demonstrated for the first time that a pure culture could ...

Reactor staging is widely used in wastewater treatment where treatment norms are achieved by connecting two or more reactors in series. The first reactor operates at high carbon source loads and the last reactor performs the final polishing. Microbial Fuel Cells (MFCs) are bioelectrochemical devices designed for direct electricity production from organic matter. Periodic connection of the MFC e...

Air-exposed microbial fuel cells and screening techniques" (2010). Introduction: Internal resistance (R int) of microbial fuel cells (MFC) has been identified as a significant variable associated to cell power output and low values are desirable (Du et al., 2007). Therefore , the aim of this research was to evaluate the effect of inoculum type and architectural features of MFC (separation of el...

In this paper we present EvoBot, a RepRap open-source 3D-printer modified to operate like a robot for culturing and maintaining Microbial Fuel Cells (MFCs). EvoBot is a modular liquid handling robot that has been adapted to host MFCs in its experimental layer, gather data from the MFCs and react on the set thresholds based on a feedback loop. This type of robot-MFC interaction, based on the fee...

Microbial Fuel Cells (MFCs) represent a still relatively new technology for liquid organic waste treatment and simultaneous recovery of energy and resources. Although the technology is quite appealing due its potential benefits, its practical application is still hampered by several drawbacks, such as systems instability (especially when attempting to scale-up reactors from laboratory prototype...

This paper presents a predictive controller for handling plug-and-play (P&P) charging requests of flexible loads in a distribution system. We define two types of flexible loads: (i) deferrable loads that have a fixed power profile but can be deferred in time and (ii) shapeable loads that have flexible power profiles but fixed energy requests, such as Plug-in Electric Vehicles (PEVs). The propos...

Abstract The transformer vibration and noise under the action of voltage current is a serious problem to equipment itself environment. In this paper, newly designed manufactured flexible DC considered. To reduce through proper installation on foundation, characteristics oil tank with different foundation designs are analysed. numerical simulation model two kinds established based FEA. convergen...
