Test results
Congratulations. You have passed the test and completed the The basics of desalination
Achieved badges:
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.
01.
Q: When examining the actual installation, what is the first thing to do?
A: Verify that air vents are present in the system, before and after the membranes.
01.
Q: When examining the actual installation, what is the first thing to do?
A: Make sure that power supply and power cables are in accordance with the nameplates.
02.
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: The measuring will ensure that the water is properly treated before it reaches the reverse osmosis membranes.
02.
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
02.
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: Because it is important to provide the operator with the instructions and the information he needs.
03.
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.
03.
Q: Why are precise dosing pumps essential in the pre-treatment process?
A: The salt cannot be removed from the water if it is not treated with chemicals.
03.
Q: Why are precise dosing pumps essential in the pre-treatment process?
A: It always looks good if a premium brand of dosing pumps is installed.
04.
Q: Why does the permeate water have to be further treated after the reverse osmosis process?
A: To ensure consumers that the water is safe to use and drink.
04.
Q: Why does the permeate water have to be further treated after the reverse osmosis process?
A: To change the colour of the water before it reaches the consumer.
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.
05.
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.
05.
Q: How does a pressure exchanger bring down the costs of production?
A: The pressure exchanger generates electricity for the intake pump.
05.
Q: How does a pressure exchanger bring down the costs of production?
A: The pressure exchanger drives a high-pressure pump.
06.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
06.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing keeps the usage of expensive chemicals to an absolute minimum
06.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing ensures reliable and efficient operation for years
