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 ...
