Abstract BACKGROUND Groundwater quality is threatened by nitrate accumulation in several regions around the world. Nitrate must be removed from contaminated groundwater to use it as drinking water. Microbial fuel cells ( MFCs ) can used for autotrophic denitrification. Thus, of a potential alternative using traditional methods treating nitrate‐polluted . RESULTS The objective this study was evaluate MFC technology treat (28.32 ± 6.15 mgN‐NO 3 − L −1 ). bioanode fed with an acetate solution...
The coexistence of different pollutants in groundwater is a common threat. Sustainable and resilient technologies are required for their treatment. present study aims to evaluate microbial electrochemical (METs) treating contaminated with nitrate (NO3−) while containing arsenic (in form arsenite (As(III)) as co-contaminant. treatment was based on the combination reduction dinitrogen gas oxidation arsenate (exhibiting less toxicity, solubility, mobility), which can be removed more easily...
The potential of nitrate electro-bioremediation has been fully demonstrated at the laboratory scale, although it not yet implemented due to challenges associated with scaling-up bioelectrochemical reactors and their on-site operation. This study describes initial start-up subsequent stable operation an pilot plant for treatment nitrate-contaminated groundwater (Navata site, Spain). was operated under continuous flow mode 3 months, producing effluent suitable drinking water in terms nitrates...
It has been recently suggested that Alcaligenes use a previously unknown pathway to convert ammonium into dinitrogen gas (Dirammox) via hydroxylamine (NH2OH). This fact alone already implies significant decrease in the aeration requirements for process, but process would still be dependent on external aeration. work studied potential of polarised electrode as an electron acceptor oxidation using described strain HO-1 model heterotrophic nitrifier. Results indicated requires metabolism,...
Elucidating the structure–function relationship of a denitrifying biocathodes.
This paper evaluates the influence of HRT and nitrate content on denitrifying BES.
Nitrate-contaminated groundwater is a pressing issue in rural areas, where up to 40 % of the population lacks access safely managed drinking water services. The high costs and complexity centralised treatment these regions exacerbate this problem. To address challenge, present study proposes electro-bioremediation as more accessible decentralised alternative. Specifically, main focus developing evaluating compact reactor designed accomplish simultaneous nitrate removal disinfection....
Hydrogen-oxidizing bacteria (HOBs) are prime candidates for the sustainable production of microbial protein because their high nutritional value and simple metabolic requirements, which could allow a resource recycling NH4+ CO2 into valuable product. The modality hydrogen production/supply to HOBs represents challenge. In this work, bioelectrochemical oxygen productions were coupled with cultivation in same reactor. Using approach, content was 59 ± 8% Hydrogenophaga Xanthobacter as most...
Electro bioremediation is gaining interest as a sustainable treatment for contaminated groundwater. Nevertheless, the investigation still at laboratory level, and before their implementation necessary to overcome important drawbacks. A prevalent issue high groundwater hardness that generates scale deposition on electrodes irreversibly affects effectiveness lifetime. For this reason, present study evaluated novel approach combining electrochemical water softening preliminary step electro of...
