Embodiment Construction
[0013] figure 1 Shown is a schematic diagram of the softened water supply system. It is mainly composed of tap water source water tank, three-stage filtration, lifting pump, ozone and ultraviolet disinfection and sterilization device, water storage tank and special pipe network for distribution to each household. The tap water is first stored in the source water tank 2, and after being pressurized by the booster pump 1, it is sequentially filtered through the automatic recoil media filter 3 that removes large particles of impurities in the water, and filters out chemical organics, heavy metals, chroma, and odors in the water. Automatic recoil activated carbon filter 4 and the automatic softening cation exchanger 5 used to reduce water hardness are also connected with a salt bucket 14 thereafter to regenerate cation exchange resin and reduce the resin replacement rate. After the three-stage filtration treatment, demineralized water with a PPM value of <45 is obtained. Deminer...
