2. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions. RO can remove dissolved or suspended chemical species as well as biological substances (principally bacteria), and is used in ...

3. Solar-powered desalination unit - Wikipedia

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

   The "reverse-osmosis solar installation" (ROSI) uses membrane filtration to provide a reliable and clean drinking water stream from sources such as brackish groundwater. Solar energy overcomes the usually high-energy operating costs as well as greenhouse emissions of conventional reverse osmosis systems.

4. Reverse osmosis plant - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis_plant

   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 ...

6. Purified water - Wikipedia

   en.wikipedia.org/wiki/Purified_water

   Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering ...

7. Ultrafiltration - Wikipedia

   en.wikipedia.org/wiki/Ultrafiltration

   Ultrafiltration. Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the ...
