SERIE SMOULD-CLUB FILTER |
WATER-NTEEING APPARATUS |
SOODIUM ION-EXCHANGING DEVICE |
|
The exchanging device is for reducing the hardness of
hard water . Raw water goes through the exchanger from top to bottom , to be softened by the sodium ion-exchanger inside the device . The positve ions of magnesium and calcuium are exchanged with that of sodium . Then the raw water becomes soft water contiaing very few ions of magnesium . The soft water can be used for boiler and for some industral uses . Due to its high dissolcing ability in water , sodium ions will not from hard sediment in the boiler and can be easily removed . Raw water shallbe filtered and settled with almost on suspended before coming into the Lonechanging device . After being softened on the device , the water's hardness shall be less than 0.03mg equivvalent/L . |
