Gansu softening, linking wealth through the production of soft water equipment (automatic water softener) by the exchange, self-control, renewable three systems group as a whole, form a single valve double column, automatic exchange floating bed, rotary valve selection of special programs , based on the principle of position control in the planning process, cycle rolling, accurate completion of each column to switch the liquid phase process, thereby completing the series of water production and automation. Gansu softening, softener works is due to the hardness of the water is mainly formed of calcium, magnesium, and said that it is generally used cation exchange resin (softener), the water Ca2 +, Mg2 + (the formation of scale main ingredient) displace, With the increase in the resin Ca2 +, Mg2 +, the resin to remove Ca2 +, Mg2 + decreased performance. Due to the hardness of water is mainly formed of calcium, magnesium, sodium principle exchange softening process is raw water exchange through the sodium cation resin, the hardness constituents in the water Ca2 +, Mg2 + and resin Na + exchanged, thus adsorption of Ca2 +, Mg2 +, the water is softened. The product features automatic control, a series of water production, simple operation, safe and efficient. Machine factory, the device is simple, simply connect the water line can be switched in and out of water production, energy saving effect is remarkable, compared with similar products contributed 50% saving, saving 60% clean water, good environmental protection. When the resin to absorb a certain amount of calcium and magnesium ions, it must be the regeneration process is the salt in the salt water rinse tank resin layer, the hardness of the resin ion exchange out in, with the regeneration waste water discharge tank, the resin He resumed soften exchange. Rational planning, small footprint, light weight of the equipment. Adaptability, with less resin, low salt consumption, low running costs.
