  • Ion exchange resin tower and detection method of lifetime of resin therein
    Patent number: 7713420
    Abstract: An ion exchange resin tower including a tank, a supply line, an output line, and a plurality of sampling tubes is provided. The supply line guides a liquid into the tank, such that an ion exchange occurs between the liquid and the ion exchange resin in the tank. The processed liquid is guided out of the tank via the output line. The sampling tubes are disposed on a sidewall of the tank to sample the liquid flowing through the resin.
