Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing prevents premature corrosion and increases system reliability
01.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing keeps the usage of expensive chemicals to an absolute minimum
01.
Q: Why is it essential that the flushing procedure runs perfectly?
A: Flushing ensures reliable and efficient operation for years
02.
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.
02.
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.
02.
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.
03.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 33%
03.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 50%
03.
Q: How much of the energy needed to drive the reverse osmosis process will a pressure exchanger provide?
A: 60%
04.
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.
04.
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.
04.
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
05.
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.
05.
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.
05.
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.
06.
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.
06.
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
06.
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.
