Increasing phosphorus recovery from dewatering centrate in microbial electrolysis cells
BACKGROUND Microbial electrolysis cells (MECs) use bioelectrochemical reactions to remove organic contaminants at the bioanode and produce hydrogen gas at the cathode. High local pH conditions near the cathode can also be utilized to produce struvite from nutrient-rich wastewater. This beneficial aspect was investigated using lab-scale MECs fed with dewatering centrate collected at a local wast...
متن کاملHydrogen production from proteins via electrohydrogenesis in microbial electrolysis cells.
Microorganisms can produce hydrogen gas (H(2)) at high rates by fermentation of carbohydrates, but not from proteins. However, it is possible to produce H(2) at high rates and yields from proteins by electrohydrogenesis in microbial electrolysis cells (MECs). Hydrogen gas was generated using bovine serum albumin (BSA, 700 mg/L) in a single-chamber MEC at a rate of Q=0.42+/-0.07 m(3)/m(3)/day an...
متن کاملPotential Use of Microbial Electrolysis Cells in Domestic Wastewater Treatment Plants for Energy Recovery
*Correspondence: Antonio Morán, Chemical and Environmental Bioprocess Engineering Group, Natural Resources Institute (IRENA), University of León, Avda. de Portugal 41, León 24009, Spain e-mail: [email protected] Globally, large amounts of electrical energy are spent every year for domestic wastewater (dWW) treatment. In the future, energy prices are expected to rise as the demand for energy reso...
متن کاملDewatering of phosphorus extracted from liquid swine waste.
Phosphorus (P) recovery from liquid swine manure is an attractive technology when on-farm application of liquid swine manure is not an option. We developed a technology that enables separation of this P, but its high moisture content makes transportation difficult. In this work, we investigated dewatering procedures to concentrate the P product. Sludge rich in calcium phosphate (> 20% P2O5) was...
متن کاملMethanobacterium Dominates Biocathodic Archaeal Communities in Methanogenic Microbial Electrolysis Cells
Methane is the primary end product from cathodic current in microbial electrolysis cells (MECs) in the absence of methanogenic inhibitors, but little is known about the archaeal communities that develop in these systems. MECs containing cathodes made from different materials (carbon brushes, or plain graphite blocks or blocks coated with carbon black and platinum, stainless steel, nickel, ferri...
