  2. Electrolysed water - Wikipedia

    en.wikipedia.org/wiki/Electrolysed_water

    An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.

  3. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    At an electricity cost of $0.06/kW·h, as set out in the US Department of Energy hydrogen production targets for 2015, [75] the hydrogen cost is $3/kg. Equipment cost depends on mass production. Operating cost depends on electricity cost for about half of the levelised product price. [72] [71] H 2 production cost ($-gge untaxed) at varying ...

    en.wikipedia.org/wiki/Mechanical,_electrical...

    Competent design of plumbing systems is necessary to prevent conflicts with other trades, and to avoid expensive rework or surplus supplies. The scope of standard residential plumbing usually covers mains pressure potable water, heated water (in conjunction with mechanical and/or electrical engineers), sewerage, stormwater, natural gas, and ...

  5. Salt water chlorination - Wikipedia

    en.wikipedia.org/wiki/Salt_water_chlorination

    Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

  6. High-pressure electrolysis - Wikipedia

    en.wikipedia.org/wiki/High-pressure_electrolysis

    Ultrahigh-pressure electrolysis is high-pressure electrolysis operating at 340–690 bars (5,000–10,000 psi). [8] At ultra-high pressures the water solubility and cross-permeation across the membrane of H 2 and O 2 is affecting hydrogen purity, modified PEMs are used to reduce cross-permeation in combination with catalytic H 2 /O 2 recombiners to maintain H 2 levels in O 2 and O 2 levels in ...

  7. Electro-oxidation - Wikipedia

    en.wikipedia.org/wiki/Electro-oxidation

    Simple scheme of the apparatus for electro-oxidation process. The set-up for performing an electro-oxidation treatment consists of an electrochemical cell.An external electric potential difference (aka voltage) is applied to the electrodes, resulting in the formation of reactive species, namely hydroxyl radicals, in the proximity of the electrode surface.
