Hardness of Inlet Water (mmol/L)
Exchange factor (mmol/L) 400 ～
1000. Down-flow regeneration, take
400 ～ 750. Up-flow regeneration,
take 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.
