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

   Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms. [1]

   Picture of a Solar Compacting Trashcan Solar-powered fountain in a bird bath under shade versus direct sunlight. The following is a list of products powered by sunlight, either directly or through electricity generated by solar panels.

5. Evaporation pond - Wikipedia

   en.wikipedia.org/wiki/Evaporation_pond

   Each pond liner is prone to leakage and requires regular maintenance. [2] The contents of the evaporation pond depend on the use, the evaporation pond will contain water and the desired contents hoping to be extracted. The desired contents range from waste to minerals, and the remaining contents are either stored or extracted. [2]

6. Aerated lagoon - Wikipedia

   en.wikipedia.org/wiki/Aerated_lagoon

   Low speed surface aerator present such high diameter. Therefore SOTE for low speed surface aerators is about 2 to 2.5 kg O 2 /kWh. This is why low speed surface aerators are mostly used in sewage or industrial treatment as WWTP [clarification needed] are bigger and sparing energy becomes very interesting.

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.
