  2. Purified water - Wikipedia

    en.wikipedia.org/wiki/Purified_water

    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 ...

  3. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    Distilled water. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water .

  4. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. Most water is purified and disinfected for human consumption ( drinking water ), but water purification may also be carried out for a variety of ...

  5. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Distillation. Laboratory model of a still. 1: The heat source to boil the mixture. 2: round-bottom flask containing the mixture to be boiled. 3: the head of the still. 4: mixture boiling-point thermometre. 5: the condenser of the still. 6: the cooling-water inlet of the condenser. 7: the cooling-water outlet of the condenser.

  6. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    There are several type of distillation: simple distillation, steam distillation etc. Water purificationcombines a number of methods to produce potable or drinking water. Downstream processingrefers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentationor synthesized by plant and animal tissues, for example ...

  7. Vacuum distillation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_distillation

    Vacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water, in order to produce fresh water. This is known as desalination . The ocean water is placed under a vacuum to lower its boiling point and has a heat source applied, allowing the fresh water to boil off and be condensed.

  8. Steam distillation - Wikipedia

    en.wikipedia.org/wiki/Steam_distillation

    Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container ...

  9. Molecular distillation - Wikipedia

    en.wikipedia.org/wiki/Molecular_distillation

    Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. [ 1] It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and ...
