Softener

The chemical reaction between hardness and resin; Ca+2 + 2 R-Na+ -----> R2-Ca + 2 Na+ Service Mg+2 + 2 R-Na+ -----> R2-Mg + 2 Na+ Service R2-Ca + 2 Na+ -----> 2 R -Na + 2 Ca+2 Regeneration (NaCl) R2-Mg + 2 Na+ -----> 2 R -Na + 2 Mg+2 Regeneration (NaCl) Hard water causes a higher risk of lime scale deposits in water systems. Due to this lime scale build-up, pipes are blocked and the efficiency of hot boilers and tanks is reduced. This increases the cost of domestic water heating by about fifteen to twenty percent. Another negative effect of lime scale is that it has damaging effects on household machinery, such as laundry machines.
