1.3 Product function
Product features:
Softening:
The SFT series softener bears many characteristics, for instance high water yield, good
water softening effect, stable operation, etc.The SFT series softener is equipped with intelligent
operations such as automatic cleaning and automatic regeneration.This product bring to you and
your family a cleaner and smoother water experience with its high water quality for your everyday
life - the ideal choice for great bathing experience, daily washing and protection for hot water appliances.
.
- Built-in 24 hours time control system. Automatic cleaning can be achieved as per the setting of
regeneration interval and time (factory preset time is 2am);
- Intelligent control system can set the most economical and effective water softening program,
automatic cleaning and regeneration program according your water condition and consumption.
- Standard cleaning and regeneration process are as follows:
After source water flow through the softener under certain pressure and flow rate, sodium ions in the
ion-exchange resin will go on an exchange with the cations (calcium ion and magnesium ion) in the
water thus reducing the consistency of those ions in water and softening.
Backwashing:
The saturated ion exchange resin needs to be backwash before regenerating. One of the reasons
for doing that is to wash off broken resin and suspended impurity that have remained on the surface of
resin. The other reason is to loosen the firm resin bed so that the resin will have a better contact with the
brine solution, providing a more favorable regeneration condition for the ion-exchange resin.
Brine washing and regeneration:
Brine solution of certain concentration and flow rate flows through the ion-exchange resin,
regenerating the saturated resin so as to restore the original softening exchange capability.
Flushing:
Flash out any residual brine solution in the resin, until the standard qualified water is achieved;
compressing the resin so as to optimize the softening effect.
Brine tank replenishment:
Replenishing brine solution for future usage during regeneration.
