2. Tile drainage - Wikipedia

   en.wikipedia.org/wiki/Tile_drainage

   Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops.

3. Water filter - Wikipedia

   en.wikipedia.org/wiki/Water_filter

   A new and advanced water purification system using reverse osmosis (RO) technology ensures 99.9% sterilization, effectively removing bacteria, viruses, dissolved salts, and heavy metals. The RO process provides high precision filtration , typically down to 0.0001 microns, ensuring the removal of harmful contaminants while preserving the purity ...

4. Solar still - Wikipedia

   en.wikipedia.org/wiki/Solar_still

   A reverse still uses the temperature difference between solar-heated ambient air and the device to condense ambient water vapour. One such device produces water without external power. It features an inverted cone on top to deflect ambient heat in the air, and to keep sunlight off the upper surface of the box.

5. Agricultural wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Agricultural_wastewater...

   Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...

6. Solar-powered desalination unit - Wikipedia

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

   In Reverse osmosis desalination systems, seawater pressure is raised above the natural osmotic pressure, forcing pure water through membrane pores to the fresh water side. Reverse osmosis (RO) is the most common desalination process in terms of installed capacity due to its superior energy efficiency compared to thermal desalination systems ...

7. Reverse osmosis plant - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis_plant

   A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment ...
