  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. Portable water purification - Wikipedia

    en.wikipedia.org/wiki/Portable_water_purification

    Portable water purification unit used by International Red Cross and Red Crescent. Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) for drinking purposes. Their main function is to eliminate pathogens, and often also of suspended ...

  4. Solar water disinfection - Wikipedia

    en.wikipedia.org/wiki/Solar_water_disinfection

    Solar thermal water disinfection uses heat from the sun to heat water to 70–100 °C for a short period of time. A number of approaches exist. Solar heat collectors can have lenses in front of them, or use reflectors. They may also use varying levels of insulation or glazing. In addition, some solar thermal water disinfection processes are ...

  5. 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 ...

  6. Organisms involved in water purification - Wikipedia

    en.wikipedia.org/wiki/Organisms_involved_in...

    Bacteria. Bacteria are probably the most significant group of organisms involved in water purification and are ubiquitous in all biological purification environments. Some such as Sphaerotilus natans are typically associated with grossly polluted waters, but even in such environments the bacteria are degrading the organic material present.

  7. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    Solar is still affordable, eco-friendly, and considered an effective method amongst other conventional distillation techniques. Solar still is very effective, especially for supplying fresh water for islanders. This makes them ideal for use in rural areas or developing countries where access to clean water is limited.
