2: How does reverse osmosis in desalination work?
In reverse osmosis, the intake water is subjected to high temperatures in order to separate salt from water through evaporation.

2: How does reverse osmosis in desalination work?
High-pressure pumps force seawater through a membrane to separate water molecules from minerals, bacteria and other impurities.
3: Why is it essential that the flushing procedure runs perfectly?
Flushing prevents premature corrosion and increases system reliability
3: Why is it essential that the flushing procedure runs perfectly?
Flushing keeps the usage of expensive chemicals to an absolute minimum

4: How does a pressure exchanger bring down the costs of production?
It transfers the pressure from the expelled brine to the intake seawater using a rotor, reducing the need for high-pressure pumps.
4: How does a pressure exchanger bring down the costs of production?
The pressure exchanger generates electricity for the intake pump.

5: Why does the permeate water have to be further treated after the reverse osmosis process?
To ensure the right PH-value and to add important minerals that have been filtered away.
6: When examining the actual installation, what is the first thing to do?
Verify the characteristics of the pumped media and the operating conditions.
6: When examining the actual installation, what is the first thing to do?
Verify that air vents are present in the system, before and after the membranes.
