This sodium ion exchanging device is used for reducing the hardness of hard water. When raw water goes through the exchanger from top to bottom, it will be softened by the sodium ion exchanger inside the device. The positive ions of magnesium and calcium are exchanged with that of sodium. Then the raw water becomes soft water containing very few ions of magnesium and calcium which can be used as feeding water of boiler and for some other industrial uses.
Due to its high dissolving ability in water, sodium ions will not form hard sediment in the boiler and can be easily removed. Raw water shall be filtered and settled with the suspended before coming into the ion-exchanging device. After being softened in the device, the water's hardness shall be less than 0.03mg equivalent/L.
