Hydrogen production with effluent from an anaerobic baffled reactor (ABR) using a single-chamber microbial electrolysis cell (MEC)

Performance, process kinetics and functional microbial community of biocatalyzed electrolysis-assisted anaerobic baffled reactor treating carbohydrate-containing wastewater

“…The anode lm was made of carbon cloth (WOS1009, CeTech, Taiwan) with an area of 54.00 cm 2 , whereas the cathode lm was made of stainless-steel mesh catalyzed by Ni nanoparticles, according to our previous studies. 26,27 The system consisted of gas measuring units (LML-1, Changchun Automobile Filter, China), a temperature control device, inlets and outlets. A water seal was used to ensure the airtightness of the reactor and to collect the biogas (Fig.…”

“…The common anaerobic treatment methods include the use of anaerobic baffled reactor (ABR), upflow anaerobic sludge blanket (UASB), microbial fuel cell (MFC), etc. A study from Wu et al (2013) was designed regarding orthogonal experiments to operate the four-compartment ABR with a hydraulic retention time (HRT) ¼ 24 h, influent COD $ 4,600 mg/L, and temperature ¼ 35 AE 1 C and discovered the optimal parameters with pH ¼ 7, C/N ¼ 44, and 2-bromoethanesulfonate (BES) concentration ¼ 20 mmol/L to achieve the high acetic acid accumulation of effluent. Dias et al (2014) presented a broad evaluation of one particular system (UASB reactor, three shallow ponds, and a coarse rock filter in series) in Brazil treating sewage from 250 inhabitants over a period of 10 years.…”

“…Reproduced by permission of Elsevier controlled release of fertilizers, an ideal system would be capable of controlling their delivery to coincide with the desired amount of the plant(Wu 2013) to avoid considerable losses due to leaching, evaporation, and other aspects of the weather. The formulations used in these technologies were obtained by the physical mixing or chemical binding of the active agent to the matrix (Kenawy and Sakran 2001).…”

Microbial electrolysis cell as an emerging versatile technology: a review on its potential application, advance and challenge

“…Electrogenic bacteria produce electrons, protons, and carbon dioxide (CO 2 ) through the biological oxidation of organic substance . Diverse organic products such as cellulose, glucose, glycerol, acetic acid, sewage sludge and complex wastewater can be transformed to an energy resource in an MEC . Electrons and protons are generated by the microorganisms on the anode and reach the cathode via an external circuit and the reactor solution respectively.…”
