2. Solar water disinfection - Wikipedia

   en.wikipedia.org/wiki/Solar_water_disinfection

   Solar water disinfection (SODIS) application in Indonesia using clear polyethylene terephthalate (PET) plastic beverage bottles. Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink.

3. Solar desalination - Wikipedia

   en.wikipedia.org/wiki/Solar_desalination

   In direct solar desalination, saline water absorbs solar energy and evaporates, leaving behind salt and other impurities. An example of this is solar stills, where an enclosed environment allows for the collection and condensation of pure water vapor. On the other hand, indirect solar desalination involves the use of solar collectors that ...

4. Solar-powered desalination unit - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_desalination...

   Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity-driven ...

5. Water pyramid - Wikipedia

   en.wikipedia.org/wiki/Water_Pyramid

   A Water pyramid or WaterPyramid is a village-scale solar still, designed to distill water using solar energy for remote communities without easy access to clean, fresh water. It provides a means whereby communities can produce potable drinking water from saline , brackish or polluted water sources.

6. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   A solar-powered desalination unit produces potable water from saline water by using a photovoltaic system to supply the energy. Solar power works well for water purification in settings lacking grid electricity and can reduce operating costs and greenhouse emissions .

7. Desalination - Wikipedia

   en.wikipedia.org/wiki/Desalination

   Off-grid solar-powered desalination units use solar energy to fill a buffer tank on a hill with seawater. [68] The reverse osmosis process receives its pressurized seawater feed in non-sunlight hours by gravity, resulting in sustainable drinking water production without the need for fossil fuels, an electricity grid or batteries.
