Reverse osmosis is a particular process of nano filtering which has the production of deionized water as a result; this water has a conductivity reduced over houndred times than the water in entrance. The rough water in boosted with pressure energy and it is sent to proper synthetic membranes. Practically the single water molecolacrosses these membranes, which hold upstream almost the totality of the salts and of the microbes. The solution that is downstream is named "permeate" and that one upstream "concentrate". the permeate is sent to the use,while the concentrate isunloaded or it is sent again to the cycle, depending on the kind of plant.

Advantages of the process

It is clear therefore that the reverse osmosis is a mechanical water treatment and so the demineralizing plants which use this technology can be defined "clean". Differing from the traditional resin systems the osmosis systems don't use the regeneration and so hurtful material such as caustic soda or hydrochloric acid which cause management and elimination problems.
