2. 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 other ...

3. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances (principally bacteria), and is used in ...

4. 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 ...

5. 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.

6. Nanotechnology for water purification - Wikipedia

   en.wikipedia.org/wiki/Nanotechnology_for_water...

   Nanotechnology is useful in regards to remediation, desalination, filtration, purification and water treatment. The main features that make nanoparticles effective for water treatment are. More surface area. Small volume. The higher the surface area and volume, the particles become stronger, more stable and durable.
