  2. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Bringing water to its boiling point (about 100 °C or 212 F at sea level), is the oldest and most effective way since it eliminates most microbes causing intestinal disease, [19] but it cannot remove chemical toxins or impurities. [20]

  3. Purified water - Wikipedia

    en.wikipedia.org/wiki/Purified_water

    Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization , reverse osmosis , carbon filtering ...

  4. Boiler water - Wikipedia

    en.wikipedia.org/wiki/Boiler_water

    Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.

  5. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    A boiling water distiller. Boiling tank on top and holding tank on the bottom. Low-volume humidifiers such as cigar humidors can use distilled water to avoid mineral deposits. [5] Certain biological applications require controlled impurities, especially in experiments. For example, distilling water to be added to an aquarium would remove known ...

  6. Chemical impurity - Wikipedia

    en.wikipedia.org/wiki/Chemical_impurity

    A mixture of water and salt can be separated by distillation, with water as the distillate and salt as the solid residue. This is done by heating the water so it boils and leaves behind the salt. The water is cooled and the gas turns back to a pure liquid. [3] Impurities are usually physically removed from liquids and gases.

  8. Boiling - Wikipedia

    en.wikipedia.org/wiki/Boiling

    The boiling point of water is 100 °C (212 °F) at sea level and at normal barometric pressure. [9] In places having a proper water purification system, it is recommended only as an emergency treatment method or for obtaining potable water in the wilderness or in rural areas, as it cannot remove chemical toxins or impurities. [10] [11]

  9. Boiling point - Wikipedia

    en.wikipedia.org/wiki/Boiling_point

    Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
