Electrocoagulation is an electrochemical method of treating polluted water whereby sacrificial anodes corrode to release active coagulant precursors (usually aluminium or iron cations) into solution. Accompanying electrolytic reactions evolve gas (usually as hydrogen bubbles) at the cathode. Electrocoagulation has a long history as a water treatment technology having been employed to remove a w...

Pyroprocessing was originally developed for the recycling of the metal fuel from a fast reactor. It was noted that pyroprocessing can be modified by an oxide reduction process enabling treatment of spent nuclear fuels from a commercial light water reactor (LWR) which is in an oxide form. Pyroprocessing treatment can reduce the volume, radioactivity, and heat load of the LWR spent fuels [1]. In ...

Introduction Effluents from the textile industry are not only colored but also contain large amounts of color, COD, BOD and dissolved solids. Textile industry is the one producing huge amount of wastewater. Due to stringent environmental regulations, treatment is mandatory before discharge the effluent. Conventional treatment methods include activated carbon adsorption, solvent extraction, chem...

The electrosynthesis of hydrogen peroxide using the oxygen reduction reaction has been studied in the absence and presence of power ultrasound in a non-optimized sono-electrochemical flow reactor (20 cm cathodic compartment length with 6.5 cm inner diameter) with reticulated vitreous glassy carbon electrode (30 x 40 x 10 mm, 10 ppi, 7 cm(2)cm(-3)) as the cathode. The effect of several electroch...

New sustainable methods are needed to produce renewable energy carriers that can be stored and used for transportation, heating, or chemical production. Here we demonstrate that methane can directly be produced using a biocathode containing methanogens in electrochemical systems (abiotic anode) or microbial electrolysis cells (MECs; biotic anode) by a process called electromethanogenesis. At a ...
