Water softener is a common piece of pre-treatment equipment for boiler feed water. Water that is too hard quickly scales up the internal components of a boiler making heat-exchange far less efficient and eventually destroying it. It also significantly reduce or completely eliminate the hassle and cost of chemical treatments to keep boilers clean.
Choosing it just can't be done properly without knowing the chemistry of the water being treated. Raw water needs to be tested for total hardness and pH, and for rural water supplies the iron and manganese levels should also be tested.
Resin is the heart and soul of every properly functioning softener. It should be replaced when any of the following occur:
high pressure loss through the softener
softening of the resin beads
allowing resin to escape the softener
It no longer fully softens the water
Resin is usually defined by the individual bead size (mesh) and the hardness (cross-link percentage). Harder one is more desirable in most applications as they allow for more softening capacity and better fouling resistance.
