2. Solar pond - Wikipedia

   en.wikipedia.org/wiki/Solar_pond

   Solar Evaporation Ponds in the Atacama Desert. The largest operating solar pond for electricity generation was the Beit HaArava pond built in Israel and operated up until 1988. It had an area of 210,000 m² and gave an electrical output of 5 MW. [3] India was the first Asian country to have established a solar pond in Bhuj, in Gujarat.

3. Water aeration - Wikipedia

   en.wikipedia.org/wiki/Water_aeration

   Subsurface aeration seeks to release bubbles at the bottom of the water body and allow them to rise by the force of buoyancy. Diffused aeration systems utilize bubbles to aerate as well as mix the water. Water displacement from the expulsion of bubbles will cause a mixing action to occur, and the contact between the water and the bubble will ...

4. Aerated lagoon - Wikipedia

   en.wikipedia.org/wiki/Aerated_lagoon

   A Typical Surface-Aerated Basin (using motor-driven floating aerators) Ponds or basins using floating surface aerators achieve 80 to 90% removal of BOD with retention times of 1 to 10 days. [6] The ponds or basins may range in depth from 1.5 to 5.0 meters. [6]

5. Floating solar - Wikipedia

   en.wikipedia.org/wiki/Floating_solar

   Floating photovoltaic on an irrigation pond. Floating solar or floating photovoltaics (FPV), sometimes called floatovoltaics, are solar panels mounted on a structure that floats. The structures that hold the solar panels usually consist of plastic buoys and cables. They are then placed on a body of water.

6. Solar desalination - Wikipedia

   en.wikipedia.org/wiki/Solar_desalination

   Solar-powered RO desalination is common in demonstration plants due to the modularity and scalability of both PV and RO systems. An economic analysis [40] that explored an optimisation strategy [41] of PV-powered RO reported favorable results. PV converts solar radiation into direct-current (DC) electricity, which powers the RO unit. The ...

7. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.
