1: 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.
2: Why is it essential that the flushing procedure runs perfectly?
Flushing prevents premature corrosion and increases system reliability
2: Why is it essential that the flushing procedure runs perfectly?
Flushing keeps the usage of expensive chemicals to an absolute minimum

4: Why are precise dosing pumps essential in the pre-treatment process?
They ensure that the exact amount of chemicals is used, keeping the cost of production to a minimum.
4: Why are precise dosing pumps essential in the pre-treatment process?
The salt cannot be removed from the water if it is not treated with chemicals.

6: Why is it important to measure the raw water, production water and brine, when the facility is switched on for the first time?
By comparing the data with the values obtained in the design phase it is possible to calibrate and balance the system to get the best possible results
6: Why is it important to measure the raw water, production water and brine, when the facility is switched on for the first time?
Because it is important to provide the operator with the instructions and the information he needs.
