The softner /sodium ion exchnager machineexchanging device is for reducing the hardnes of hard water. Raw water goes through the exchanger from top to bottom, to be softened by the sodium iom-exchanger inside the device. The positve ions of magneaium and calcium are exchaged with that of sodium. Then the raw water becomes soft water contiaing very few ions of magnesium and calcium. The soft water can be used for feeding water of boiler and for some industral 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 shallbe filtered and settled with almost on suspended before coming into the the Lonechaging devece. After being softened in the device, the water' shardness shall be less than 0.03mg equivvalent /L.   

Widely used in pretreatment of pure water production line in boiler, thermal power station, chemical, light industry, textile, medicine, biology, electronic, atomic energy; hard water soften and deionization in industrial processing; purification of food and drugs, reuse of precious metals and chemical raw materials, waste water of electroplating, ect.
