Which is mainly composed of water hardness cations: Calcium (Ca2 +), magnesium (Mg2 +) ions constituted. As with the hardness of raw water through the exchanger resin layer, water calcium and magnesium ions adsorbed to the resin, while the release of sodium ions in the water flowing out of this exchange is to remove the softened water hardness ions, when the resin adsorption of calcium, After the magnesium ions reach a certain saturation, the water hardness is increased, then the softener will be in accordance with a predetermined program automatically fail resin regeneration work, the use of higher concentrations of sodium chloride solution (saline) through the resin, so that the failure of resin restored to sodium type resins. Softening principle resin separation softener technology is through water sodium ion exchange softening, is the raw water through the sodium ion exchangers, water, Ca2 +, mg2 + is exchanged agent Na + replaced, make change easy scaling of calcium and magnesium compounds are not scale-forming water soluble sodium compound leaving softened. Automatic sodium ion exchange is mainly composed of multiple control valves, controllers, resin tank (water inside cloth), salt box composition, multiple control valve valves in the same valve body multiple paths, the controller according to the set The program instructions to the occurrence of multiple valves, multiple valves automates several valve switching. Enabling operation, backwash, regeneration, replacement, regular washing program without setting saline pump. Simple equipment, can be widely used in the preparation of industrial and civil use of softening, such as steam boiler feed water, heating and air conditioning, pools and other water systems. Nano technology, which TemplateAsistedCrystallization (module auxiliary crystals), the use of high energy nanocrystals produced, the water free of calcium, magnesium, bicarbonate ions packed into nano-crystals, thereby preventing the free ions to build scale. Work program 1, water: untreated water through the resin layer, the occurrence of exchange reaction, resulting in soft water. 2. Backwash: water from the lower portion of the resin layer, loose resin, to remove the crushing debris. 3, into the brine regeneration: the use of a high concentration of salt (Nacl) flows through the resin, the resin will fail again revert to the sodium available resins. 4. Rinse: according to the flow of water when the water through the resin flush out excess calcium salt solution and regeneration exchange down, magnesium ions. 5, water: water inside the salt to dissolve salt, used to prepare for the next regeneration. Removing the water softening process calcium: CaCO3 + 2Na-R = Ca-R + Na2CO3 Ca (HCO3) 2 + 2Na-R = Ca-R + 2NaHCO3 magnesium removal: MgCO3 + 2Na-R = Mg-R + Na2CO3 Mg ( HCO3) 2 + 2Na-R = Mg-R + 2NaHCO3 softened resin strong acid cation exchange resin discoloration, mainly used in water softening, water preparation, household drinking fountains, water purifiers. It can be observed using the intuitive operation of the resin through the resin color change. The product is a green spherical particles, after the failure to purple spherical particles, can be repeated use of renewable.
