Hard water refers to water with more calcium and magnesium ions, while soft water refers to water with fewer calcium and magnesium ions. The way to tell hard water from soft water is to use soapy water or heat. If the water hardness is relatively high, a large amount of scale will be produced. If there is too much scale, the boiler risks exploding, which is quite dangerous. So the answer is: if the water hardness is relatively high, a large amount of scale will be produced. Too much scale will cause the boiler to explode, which is more dangerous. Therefore, hard water cannot be used in the boiler.

Is the water after ion exchange in the boiler pure water?
Raw water hardness: 3-10 mg-N/L (1 mg-N/L = 2.8 German degrees = 50 mg/LCaCO3 hardness), if the water hardness raw is greater than 10 mg-N/L, increase size when selecting A model may use secondary softening.

< p >Ion exchange resin is a polymer with corresponding functional gene groups. Generally, conventional sodium ion exchange resins contain a large amount of sodium ions.When the content of calcium and magnesium ions in water is high, the ion exchange resin can release sodium ions, and the functional gene groups combine with calcium and magnesium ions, so as the calcium content and magnesium ions in the water decrease and the hardness of the water decreases. Hard water becomes soft water, which is the process of foperation of water softening equipment.
When a large number of functional gene groups on the resin are combined with calcium and magnesium ions, the softening ability of the resin decreases. A sodium chloride solution can be used to circulate through the resin. the content of sodium ions in the solution is high, and the functional genes The group will release calcium and magnesium ions and combine with sodium ions, so that the resin restores its exchange capacity. This process is called "regeneration."
Using ion-exchanged water, as you said, only removes calcium and magnesium ions, while other substances (it There are generally more than 20 industry standards for groundwater inspection and more than 50 food standards) are still retained in water. called “softened water” and is in no way “pure water” or “distilled water”. So where are they going?he sodium ions in NaCl treated with salt? There are two types of ion exchange resin, one is called sodium type, which is 007*7, and its regenerant uses sodium chloride. In fact, after the raw water passes through the ion exchanger, the calcium and magnesium ions are not precipitated, but are adsorbed on the resin particles by the resin. When the resin particles are saturated with calcium and magnesium ions, we use table salt for. exchange them, and calcium and magnesium exchanged. The ions are then flushed out with water, a process called “regeneration.” Then perform a “positive wash,” which also involves rinsing and then removing the remaining sodium chloride.
