WebbSplitting water into oxygenand hydrogenhas the potential to fuel the global economy more sustainably, but the technology is held back by the bottleneck of oxidising water to molecular oxygen. Now, a group of researchers from Trinity College Dublin, Ireland, led by Max García-Melchor, think they have found a way to overcome this hurdle. Webbtreatment requires a great amount of electricity, consumed by compressors, for increasing the amount of dissolved oxygen (DO) in water, which is consumed by microorganisms in order to reduce BOD up to 85% and total nitrogen (N tot) up to 70 %. (Malik, 2014; Binh, 2013) The tertiary step uses advanced technologies to remove the remaining pollutants.

WebbThe basic principle of electrolysis is to split water into oxygen and hydrogen with the help of electricity. The splitting occurs in two partial reactions that take place at the two electrodes – cathode (-) and anode (+) – in the electrolysis cell. In practice, electrolysers consist of several interconnected electrolysis cells, also called ... WebbCalculation for 1 kg of water (55.55 moles): Energy for electrolysis: 237.13 kJ * 55.55 = 13.173 MJ Energy released by Hydrogen combustion: 0.002 * 55.55 * 141.86 MJ = 15.76 MJ These calculations are not taking in account efficiency and energy loses, they are purely theoretical. daks bossier city
