The purpose of creating an automatic reverse osmosis unit is to treat water, concentrate juices and separate solutes from the solvent. This controlled system based on a programmable automaton displays the input and output variables on the supervision screen to be able to understand the operation and modify the input parameters according to user needs.

Firstly, this device created at the national level makes it possible to avoid importation so it will therefore be widely available with a reasonable price, therefore we will contribute to the development of the country's economy.

Second, since this system is flexible; it facilitates the tasks to the users and thus to have fast and very precise service.

Finaly, the drought threatened several countries including ours (Algeria). To be able to utter it we have recourse to the desalination of the water of the seas and the oceans like fundamental apparatus to satisfy the water needs.

It is possible to maintain system parts one by one and get a new reverse osmosis unit.

the water needs either for the populations or the industries never ends therefore the demand for this device never ends

- process; based on a programmable logic controller -a continuous improvement approach: improve the system and have remote control and remote software part maintenance - security tools: - the alarm -the supervision screen
