How it works: Water hardness cations which are mainly: calcium (Ca2 +), magnesium (Mg2 +) ion composition. 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. Thus from the switch out of the water is to remove the softened water hardness ions, when the absorption of calcium, magnesium ions after the resin reaches a certain level, water hardness increases, this time in accordance with a predetermined program softener automatically fail resin regeneration work , the use of higher concentrations of sodium chloride solution was passed through the resin so that the failure of the resin to the sodium form resin is restored. Applications: industrial boilers, central air conditioning, heat exchangers, hotels, food, chemical, printing and dyeing laundry, health care and other industries. Main features: a high degree of fully automated, stable water conditions, long service life. Full automatic operation, only artificial regular salt. 2, high efficiency, low energy consumption, low operating costs. Since the water softener overall design is reasonable, so that the exchange capacity of the resin to be fully exploited. The device itself was significantly lower than the energy consumption index operator general softening equipment, automatic control devices do not require full-time, which gave users a lot of convenience, and produce good results. ??? Water consumption: <2% of water production. ??? Salt consumption: one liter of resin regeneration takes about 160 to 240 grams of salt, salt consumption is to be determined based on the specific user raw water quality indicators. ??? Power consumption: 3 ~ 40W, because no salt pump, and general lighting with 220V power supply, the power consumption of only 1% of normal water softener. 3, compact structure, small footprint, no special equipment based directly on a flat concrete floor can be. 4, easy to use, installation, commissioning, operation is simple, stable performance control components, can relieve the user's worries. 5, corrosion, pollution, lead-free brass control valve, lined with non-toxic PE plastic tank exchange, PE material salt boxes, which are sufficient to ensure that the equipment corrosion, anti-pollution, non-toxic, odorless, excellent sound performance. Work program:? Water: untreated water through the resin layer, the occurrence of exchange reaction, resulting in soft water. ? Backwash: Water enters from the lower part of the resin layer, loose resin, remove the crushing debris. ? Regeneration salt intake: the use of a high concentration of salt (NaCl) to flow through the resin, the resin will fail again reduced to sodium type available resins. ? Flushing: follow the flow of water when the water flushing excess salt through the resin solution and regeneration exchange down the calcium and magnesium ions. ? Water: inside the salt water, dissolve salt, used to prepare for the next regeneration. Control: 1. Time control: Suitable for daily water supply of more stable place, when it reaches the user to set the time automatically start the regeneration process of regeneration, 2. Regeneration can set their own time at low water peak according to the user's needs. The control method includes: a control is simple, cheap, easy to operate features. The system is mainly used for low hardness (4mmol / L), stable water (water fluctuations in the amount of not more than 15%), water less demanding, less water situation. 3. Flow Control: Run by the device to calculate the flow meter. When the water reaches the set value, automatically starts regeneration. Set value of water is based on the work of the exchange and the exchange of equivalent value when the water hardness value calculated. The system has high accuracy, stable and reliable water with memory function, do not need to re-set the value after a power outage.
