Correct
01.
Q: Why is it important to measure the raw water, production water and brine, when the facility is switched on for the first time?
A: 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
Correct
02.
Q: Why are precise dosing pumps essential in the pre-treatment process?
A: They ensure that the exact amount of chemicals is used, keeping the cost of production to a minimum.
Correct
03.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
Correct
04.
Q: Why does the permeate water have to be further treated after the reverse osmosis process?
A: To ensure the right PH-value and to add important minerals that have been filtered away.
Correct

Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 60%
Correct

Q: How does reverse osmosis in desalination work?
A: High-pressure pumps force seawater through a membrane to separate water molecules from minerals, bacteria and other impurities.
