Water is one of the most abundant worldwide and is part of the most polluted or cloudy, located in rivers, seas, oceans and this is the last thing you can find the 97.25 water that exists throughout hydrosphere.
The seas and oceans contain salt water, this may be subjected to purification treatments thanks to the universality of its membership, giving patterns that contains element types and how they can extract or exploit them for use in various systems .

Part of a type of water treatment is called "osmosis", which consists in finding a certain balance of substances; here told two fluids enter and blend until unify the amount of dissolved substances containing separately. If this process is made containing a permeable membrane that separates and is in the midst of both fluids, the fluid that moves through the barrier will be less concentration of dissolved solids to the conclusion that has more of them. So eventually one side stay with more water, and this difference in level between the two fluids is called the osmotic pressure.

In this there are 3 water treatment processes or stages that form part of the same main goal is to get more pure water and remove those elements that obscure their performance:
The first process that is subjected to water is the one described above as "Osmosis", through which strikes a balance between dissolved solids and thus passed the third and last one is called "reverse osmosis". The latter uses a higher osmotic pressure, causing the opposite effect that the osmosis, pushing the fluids through the membrane and leaving behind solids that are dissolved in liquid whole unpurified. If using a pressure above the osmotic pressure, it produces the opposite effect. Fluids are pressed through the membrane while dissolved solids stay behind.

It is necessary to conduct the reverse osmosis process for purification of water, since through the membranes is accomplished by passing the water that the stream determined as brine, into a stream with a lower concentration of salt as outcome will be a greater concentration of the brine.
