Exchange capacity
9. Exchange capacity.
The unit of exchange capacity is dependant on the unit chosen in step 8.
It gives the amount of softened water in m
3
as indicated in the chosen
unit of hardness.
The amount of water which can be softened by each unit is automatically
calculated as follows:
Example 1:
36000mg
CaCO
3
x 1000
=100 m
3
360mg (/l CaCO
3
}
or
Example 2:
2020 °F m
3
= 50 ,5m
3
40 °F
The exchange capacity can be entered as a numeric value in the range of 10 and 655,350.
IMPORTANT
Regardless of whether the installation is a simplex or duplex plant only enter the
capacity of one exchange column.
