Correct
01.
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
02.
Q: When examining the actual installation, what is the first thing to do?
A: Verify the characteristics of the pumped media and the operating conditions.
Correct
03.
Q: How does a pressure exchanger bring down the costs of production?
A: It transfers the pressure from the expelled brine to the intake seawater using a rotor, reducing the need for high-pressure pumps.
Correct
04.
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.
Correct
05.
Q: Why are beach wells with submersible pumps the optimal intake method for smaller desalination plants?
A: The water passes through sand, which acts as a natural filter and eliminates the need for prefiltration in the plant
Correct
06.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
