The coupling of constructed wetlands (CW) to microbial fuel cells (MFC) has become a promising hybrid technology due its high compatibility generate electricity and remove pollutants from wastewater. In the present study, bioelectricity production generated wetlands-microbial (CW-MFCs) was evaluated using four species shade macrophytes: Aglaonema commutatum, Epipremnum aureum, Dranacaena braunni, Philodendron cordatum. CW-MFCs were operated in continuous upflow mode with hydraulic retention...
Two different air-cathode stacked microbial fuel cell (MFC) configurations were evaluated under continuous flow during the treatment of municipal wastewater and electricity production at a hydraulic retention time (HRT) 3, 1, 0.5 d. Stacked MFC 1 was formed by 20 individual units. The second (stacked 2) consisted 40 units placed in shared reactor. maximum voltages produced closed circuit (1,000 Ω) 170 mV for 94 2. Different power densities each unit obtained due to potential drop phenomenon...
Constructed wetlands-microbial fuel cells (CW-MFC) are an innovative technology used for simultaneous bioelectricity generation and wastewater treatment. This is possible due to the installation of macrophytes in electrode configuration, which electroactive microorganisms use organic substrates as biofuel. One way improve electrochemical performance CW-MFCs through impregnation cathodic electrocatalysts. Therefore, this study production capacity was evaluated from oxygen reduction reaction...
The effect of different concentrations tylosin on methane production was investigated: first methanogenesis in a biomass without contact with the antibiotic, and later ability sludge to adapt increasing tylosin. Results showed that, for that had no presence inhibits generation even at as small 0.01 mg L−1, samples above 0.5 L−1 produced practically methane, whereas, digesters acclimated concentration 0.065 is not inhibited antibiotic improved. This behaviour suggests microorganisms have...
The biological degradation of estrone (E1), estradiol (E2) and ethinylestradiol (EE2) was studied in batch experiments at typical concentration levels using nitrifying activated sludge from a membrane bioreactor (MBR). Since first-order, pseudo first-order Monod-type kinetics were observed. Pseudo first order kinetic reformulated only the soluble concentrations S assuming adsorption coefficient KD estrogens. For coefficients determination, MBR spiked with respective target compounds stirred....
Mezcal is a drink made in Mexico, the production of which generates vinasses with high content organic matter (OM) that not utilized. However, these residues have potential to be drawn upon dark fermentation (DF) processes obtain biogas rich biohydrogen, biomethane, and volatile fatty acids (VFAs) become biofuels. In present work, effect reaction time (RT) load (OL) was assessed based on efficiency removing OM, VFAs, generation composition process DF fed mezcal vinasses. The results show...
An integrated fluidized bed reactor (FBR) has been employed as the treatment for petrochemical industry wastewaters with high organic matter and aromatic compounds, under anaerobic aerobic conditions. The system was operated at hydraulic residence time (HRT) of 2.7 2.2 h in reactor, respectively. degree fluidization beds 30%. This showed a performance on removal compounds. At different loading rates (OLR), chemical oxygen demand (COD) close to 85% removals COD up 94% were obtained reactor....
Based on a literature review, set of inhibition indicators is presented for each stage anaerobic digestion according to the behavior certain parameters: reduction total COD/soluble COD ratio; low volatile fatty acids (VFA) production; accumulation VFA and acetate methane production. Moreover, we present several preventive recovery strategies considering detected indicator. Some are acclimation microorganisms degrade organic-matter in presence inhibitors, enrichment inoculum with various...
The purpose of this paper is to report the study fate and distribution three endocrine disrupting compounds (estrogens); Estrone (E1), 17β-estradiol (E2), 17α-ethinylestradiol (EE2) in a laboratory scale submerged membrane bioreactor (SMBR). For matter, both aqueous solids phases were analyzed for presence E1, E2 EE2. outcome was that SMBRs showed enhanced elimination estrogens different operational conditions; estrogen removal close 100% SMBR. Additionally, EE2 detected SMBR sludge at...
The purpose of this study was to evaluate the simultaneous production bio‐electricity and bio‐hydrogen using a novel continuous flow single chamber hydrogen‐producing microbial electrochemical reactor (sMER‐H 2 ). inocula tested were: raw municipal wastewater (I 1), sporulated Gram‐positive bacteria 2), mixture anaerobic granular sludge with sediments thermally pretreated 3). best performance for bioelectrochemical hydrogen occurred when inoculum I 3 tested. maximum voltage generated an...
Constructed wetland-microbial fuel cells (CW-MFCs) systems are a sustainable technology capable of producing bioelectricity and treating wastewater simultaneously. It is also possible to obtain from the photosynthetic substrates obtained by rhizodeposition macrophytes, where electroactive microorganisms present in rhizosphere use these compounds as biofuel. In study, production capacity Juncus effusus Philodendron cordatum species was evaluated CW-MFC without an external carbon source. The...
This study determined a tylosin concentration in swine wastewater located Mexican pig farm, during different stages of the pigs' growth. The detection antibiotics is complex due to its high solids. Analytical method was developed for and slurry. Average recoveries liquid solid phase were greater than 51 44%, respectively, with total recovery 95%. results indicated presence slurry at concentrations ones reported literature.
