Desalination system and elements thereof

A membrane system comprising at least two adjacent membranes adapted to be connected to each other comprising at least one sensor adapted to measure at least one of the following:

• a) quality of a fluid passing through said membrane;
• and
• b) flow rate of a fluid passing through said membrane.

A pressure vessel adapted to receive one or more desalination membranes, said pressure vessel includes at least one sensor, said sensor adapted to measure at least one of the following:

• a) quality of a fluid passing through at least one of said membranes at the area of the coupling;
• and
• b) flow rate of a fluid passing through at least one of said membranes at the area of the coupling.

A membrane adapted to be connected to at least one sensor, said sensor adapted to measure at least one of the following:

• a) quality of a fluid passing through said membrane;
• and
• b) flow rate of a fluid passing through said membrane.

The membrane of claim 36, wherein said sensor is operated continuously, measuring parameters throughout its operation or said sensor is adapted to operate in bursts, sampling the above parameters along predetermined periods of time.

A desalination system comprising at least one row of PVs, each having a feed inlet at a first end thereof and a brine outlet at a second end thereof and containing at least one desalination membrane, said PV being adapted for passage of fluid to be desalinated between said first and said second end, wherein said feed inlet is fitted with a first sensor adapted for acquiring a first set of parameters of a test substance introduced into said fluid and passing therealong inside the PV, and said brine outlet is fitted with a second sensor adapted for acquiring a second set of parameters of the test substance.
