Reverse osmosis is a very useful process for the purification of seawater or brackish water.

Water treatment systems can supply freshwater to a small town or industry. There are different individual or industrial reverse osmosis units that carry out desalination to produce quality water according to your daily needs.

This pure, potable water has advantages, but it also has disadvantages.

The membranes do not work on their own, because it is necessary to install a pretreatment with chlorine, then a dechlorination and finally an elimination of boric acid.
Desalinating seawater or less salty brackish water, but unfit for consumption to obtain fresh drinking water for domestic and industrial use is an ecological solution in isolated areas.
