Capacity & salt consumption for the different salt dosage setting
* Foleo is featured with variable refill therefore the salt quantity required is calculated by the controller at each regeneration start. This
maximum amount correspond to cases where 100% of the capacity would have been exhausted or to what a standard softener without
variable refill would consume.
Note
This example is calculated for a salt dosage fop 80 g/L
resin
. Should the inlet hardness be grated the
30°F it may be required to increase the salt dosage to obtain a proper resin bed regeneration. The
same simulation with 120 g/L
resin
lead to an estimated average salt saving of 35,5%, while the same
simulation done at 160 g/L lead to an estimated salt saving of 46%.
