  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

    In contrast to PEM electrolysis, AEM electrolysis allows for the conduction of hydroxide ions. A noteworthy benefit of AEM-based water electrolysis is the elimination of the need for expensive noble metal catalysts, as cost-effective transition metal catalysts can be utilized in their place.

  4. Anion exchange membrane electrolysis - Wikipedia

    en.wikipedia.org/wiki/Anion_exchange_membrane...

    Anion exchange membrane (AEM) electrolysis is the electrolysis of water that utilises a semipermeable membrane that conducts hydroxide ions (OH −) called an anion exchange membrane. Like a proton-exchange membrane (PEM), the membrane separates the products, provides electrical insulation between electrodes, and conducts ions.

  5. Erosion corrosion of copper water tubes - Wikipedia

    en.wikipedia.org/wiki/Erosion_corrosion_of...

    Erosion corrosion, also known as impingement damage, is the combined effect of corrosion and erosion caused by rapid flowing turbulent water.It is probably the second most common cause of copper tube failures behind Type 1 pitting which is also known as Cold Water Pitting of Copper Tube.

  6. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    A low voltage DC current is applied, electrolysis happens producing sodium hypochlorite and hydrogen gas (H 2). The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and sodium chloride are used. The simplified chemical reaction is: NaCl + H 2 O + energy → NaOCl + H 2 [citation needed]

  7. Galvanic corrosion - Wikipedia

    en.wikipedia.org/wiki/Galvanic_corrosion

    In most HVAC systems, the use of sacrificial anodes and cathodes is not an option, as they would need to be applied within the plumbing of the system and, over time, would corrode and release particles that could cause potential mechanical damage to circulating pumps, heat exchangers, etc. [5]
