Bioremediation in Water Environment: Controlled

Microbial Fuel Cell is a BES which generates electricity, and Microbial Electrolysis Cell (MEC) is a BES requiring a power supply to drive non-spontaneous reactions. Many of the recent advances in the electron transfer between microbes and electrodes have arisen from the study of MFCs, devices initially designed for harvesting electricity from OM degradation [14] [79] [80] .

The Green Latrine: Development of a Large Scale

microbial electrolysis cell (MEC) of 910 L (liquid volume) to produce hydrogen gas from treating winery wastewater in Oakville, CA. After an intensive start-up period that explored pH and temperature effects on power, it produced a maximum current density of 7.43

Bioelectrochemical Denitrification for the Treatment of

Because the latter process may use microorganisms to catalyze nitrate reduction at the biofilm–electrode interface, the process can be referred to as bioelectrochemical denitrification. (14) In a typical bioelectrochemical system (BES) performing denitrification, electrons can be generated abiotically by electrolysis of water at the anode with simultaneous production of oxygen gas.

2021/4/30Co-culture of algae and activated sludge increased NH 3-N removal up to 43.89% A decrease up to 79.60% of fouling precursors was found in the MBR with algae • Electric field application to MBR with algae increased PO 4 3-P removal by 65.60% Algae-bacteria

Sustainability

Emerging pollutants in the form of pharmaceuticals have drawn international attention during the past few decades. Ciprofloxacin (CIP) is a common drug widely found in effluents from hospitals, industrial and different wastewater treatment plants, as well as rivers. In this work, the lab-scale 3D-BER system was established, and more than 90% of the antibiotic CIP was removed from Low C/N

Frontiers

In such a system, denitrification can still occur at a higher dissolved oxygen level than that of a conventional SND process. The main explanation for this finding was the formation of a micro-environment on the porous surface of graphite granule where denitrifying bacteria could grow ( Virdis et

Applied voltage optimization for denitrification process

Microbial Electrolysis Cell (MEC) is a type of bioelectrochemical system (BES) that is connected to external power source to aid the reactions. This research investigates the effect of applied voltage value on denitrification by nitrate removal efficiency of two model denitrifying species from the genus Pseudomonas in single-chambered MEC.

2017/5/31The end products of denitrification are nitrogen gas, new cell biomass, and hydroxyl ion, as well as an increase in pH, which is not a concern in the denitrification process (Lew et al. 2012). The electrons required for reducing nitrate are provided by specific organic and inorganic electron donors in both heterotrophs and autotrophs (Matějů et al. 1992 ; Ashok and Hait 2015 ).

In the process of opening the main circuit of the equipment, the over-voltage phenomenon of the transformer occurs, which leads to the phenomenon of electric spark explosion. Through the accident analysis, a series of rectification measures are obtained, which will play a reference role for the subsequent maintenance and operation of wind turbines.
