suggested to lengthen 1~2 minutes of calculated brine refilling time to
make sure there is enough water in tank. (The condition is that the there
is a level controller installed in the brine tank)
⑤ Fast rinse time T5
T5=12×H
R
(min.)
Generally, the water for fast rinse is 3~6 times of resin volume. It is
suggested to be set 10~16 minutes, but subject to the outlet water
reaching the requirement.
⑥ Exchange factor
Exchange factor =E/ (k×1000)
In this formula, E——Resin working exchange capability (mol/m
3
), it
is related to the quality of resin. Down-flow regeneration, take 800~900.
Up-flow regeneration, take 900~1200.
K——Security factor, always take 1.2~2. it is related to the hardness
of inlet water: the higher the hardness is, the bigger the K is.
⑦ Regeneration time
The whole cycle for generation is about two hours. Please try to set
up the regeneration time when you don’t need water according to the
actual situation.
The calculation of parameters for each step is only for reference, the
actual proper time will be determined after adjusting by water exchanger
supplier. This calculation procedure of softener is only for industrial
application; it is not suitable for small softener in residential application.
