  2. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.

  3. Dealkalization of water - Wikipedia

    en.wikipedia.org/wiki/Dealkalization_of_water

    Dealkalizers are most often used as pre-treatment to a boiler and are usually preceded by a water softener. Alkalinity is a factor that most often dictates the amount of boiler blowdown. High alkalinity promotes boiler foaming and carryover and causes high amounts of boiler blowoff.

  4. Water capacitor - Wikipedia

    en.wikipedia.org/wiki/Water_capacitor

    Unlike many large, industrial, high voltage capacitors, water capacitors do not require oil. Oil found in many older designs of capacitors can be toxic to both animals and humans. If a capacitor breaks open and its oil is released, the oil often finds its way into the water table, which can cause health problems over time. [13]

    en.wikipedia.org/wiki/Capacitor_plague

    Failed aluminium electrolytic capacitors with open vents in the top of the can, and visible dried electrolyte residue (reddish-brown color) The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, [1] [2] due to faulty electrolyte composition that ...

  6. Electrolytic capacitor - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_capacitor

    A capacitor can also act as an AC resistor. aluminium electrolytic capacitors in particular are often used as decoupling capacitors to filter or bypass undesired AC frequencies to ground or for capacitive coupling of audio AC signals. Then the dielectric is used only for blocking DC.

  7. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.

  8. Metal ions in aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Metal_ions_in_aqueous_solution

    A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+. The solvation number , n , determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table .

    where R is the gas constant (8.314 J mol −1 K −1), T the temperature (K), Φ v,fresh, the flow rate of the fresh water outflow (m 3 /s), C feed the concentration of ions in the feed water (mol/m 3) and C fresh the ion concentration in the fresh water outflow (mol/m 3) of the CDI cell.
