Test results
Congratulations. You have passed the test and completed the The basics of desalination
Achieved badges:
01.
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.
01.
Q: How does a pressure exchanger bring down the costs of production?
A: The pressure exchanger generates electricity for the intake pump.
01.
Q: How does a pressure exchanger bring down the costs of production?
A: The pressure exchanger drives a high-pressure pump.
02.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 33%
02.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 50%
02.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 60%
03.
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.
03.
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.
03.
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.
04.
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.
04.
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
04.
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.
05.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
05.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing keeps the usage of expensive chemicals to an absolute minimum
05.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing ensures reliable and efficient operation for years
06.
Q: Why are beach wells with submersible pumps the optimal intake method for smaller desalination plants?
A: A beach well is a very cheap solution for water intake.
06.
Q: Why are beach wells with submersible pumps the optimal intake method for smaller desalination plants?
A: A beach well intake will prevent chemical use in the desalination plant.
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
