Test results
Congratulations. You have passed the test and completed the 28 - The basics of desalination
Achieved badges:
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.
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.
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.
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.
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.
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: How does reverse osmosis in desalination work?
A: In reverse osmosis, the intake water is subjected to high temperatures in order to separate salt from water through evaporation.
Q: How does reverse osmosis in desalination work?
A: Reverse osmosis is a normal filtration process in which water passes through a filter.
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: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 33%
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 50%
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 60%
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 a pressure exchanger bring down the costs of production?
A: The pressure exchanger generates electricity for the intake pump.
Q: How does a pressure exchanger bring down the costs of production?
A: The pressure exchanger drives a high-pressure pump.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing keeps the usage of expensive chemicals to an absolute minimum
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing ensures reliable and efficient operation for years
