Correct
01.
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
02.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
Correct
03.
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
04.
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
05.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 60%
Correct
06.
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
