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
Generally, it is suggested to set 10～15 minutes. The higher the
turbidity is, the longer backwash time shall be set. However, if the
turbidity is more than 5FTU, it is better to install a filter in front of the
exchanger.
