Sorry. You did not pass the 28 - The basics of desalination test this time

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.
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.
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
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
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
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.
