  2. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Brine draw: Water is directed through a jet pump, which pulls salt water from the brine tank, before the water and brine pass through the resin bed in the normal direction, if co-current, or in the reverse direction, if counter-current. [12] The output of this typically thirty-minute process is discarded through the drain hose.

  3. Dealkalization of water - Wikipedia

    en.wikipedia.org/wiki/Dealkalization_of_water

    Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...

  4. Potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate

    It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution. Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent , and also as a medication for dermatitis , for cleaning wounds , and general disinfection .

  5. Softener - Wikipedia

    en.wikipedia.org/wiki/Softener

    Softener may refer to: Fabric softener , a conditioner that is typically applied to laundry during the rinse cycle in a washing machine. Stool softener , anionic surfactants that enable additional water and fats to be incorporated in the stool, making it easier for them to move through the gastrointestinal tract.

  6. Bromotrifluoromethane - Wikipedia

    en.wikipedia.org/wiki/Bromotrifluoromethane

    It does not produce the characteristic white cloud like CO 2 and is difficult to direct when fighting large fires. Halon 1301 is ideal for armored vehicles and spacecraft, because it produces fewer toxic by-products than does Halon 1211 , which is critical for combat or space conditions where a compartment may not be able to be ventilated ...

  7. Propane, butane, and LPG container valve connections

    en.wikipedia.org/wiki/Propane,_butane,_and_LPG...

    The EN 417 norm specifies container construction, but does however not specify any connectors. IS-8737 [11] Indian standard for LPG connectors for use with cylinders of more than 5 liter water capacity. [12] KHK S0126 Japanese standard for LPG container valve design and manufacturing. [13] SAEF American standard specified by U.S. based SAE ...

  8. Dow process (bromine) - Wikipedia

    en.wikipedia.org/wiki/Dow_process_(bromine)

    In the original invention, bromide-containing brines are treated with sulfuric acid and bleaching powder to oxidize bromide to bromine, which remains dissolved in the water. The aqueous solution is dripped onto burlap, and air is blown through causing bromine to volatilize. Bromine is trapped with iron turnings to give a solution of ferric bromide.

  9. Water treatment - Wikipedia

    en.wikipedia.org/wiki/Water_treatment

    In California, more than 4% of the state's electricity consumption goes towards transporting moderate quality water over long distances, treating that water to a high standard. [34] In areas with high quality water sources which flow by gravity to the point of consumption, costs will be much lower. Much of the energy requirements are in pumping.
