2. Solar water disinfection - Wikipedia

   en.wikipedia.org/wiki/Solar_water_disinfection

   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. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.

3. Solar desalination - Wikipedia

   en.wikipedia.org/wiki/Solar_desalination

   RO is the most common desalination process due to its efficiency compared to thermal desalination systems, despite the need for water pre-treatment. [39] Economic and reliability considerations are the main challenges to improving PV powered RO desalination systems. However, plummeting PV panel costs make solar-powered desalination more feasible.

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 ...

6. 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.

7. 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 .
