Hardness of Inlet Water (mmol/L).
Exchange factor (mmol/L) 400～1000.
Down-flow regeneration, 400～750；
Up-flow regeneration, 450～1000.
If the inlet water hardness is higher,
the factor is smaller.

② Backwash time T2
It is subject to the turbidity of inlet water. Generally, it is suggested to
be set 10～15 minutes. The higher the turbidity is, the longer backwash
time can be set. However, if the turbidity is more than 5FTU, it should be
better to install a filter in front of the exchanger.
