  • Patent number: 7217346
    Abstract: There is provided a water treating method which can not only improve an effect of eliminating microorganisms in water intended for cooking and drinking or waste water but also prevent a reduction in trace amounts of nutritional elements. In the method, at least a pair of carbon fibers capable of collecting at least microorganisms are immersed in for-treatment water, potentials of opposite polarities are applied to the carbon fibers, and the polarities of the potentials are switched at a predetermined time interval so as to adsorb the microorganisms on the carbon fibers. After the microorganisms are adsorbed, a positive potential is applied to one of the carbon fibers, and a negative potential is applied to the other so as to cause electrolysis. Then, an alternating voltage is applied to the carbon fibers so as to heat the for-treatment water and the carbon fibers.

  • Patent number: 7135099
    Abstract: In a circulation system of treatment-object water (waste water), a water treating apparatus and a pH adjuster are provided. A carbon fiber that can collect at least microorganisms is disposed in the water treating apparatus. The carbon fiber is immersed in the treatment-object water, and potential is applied to the carbon fiber. Further, pH of the treatment-object water is adjusted by the pH adjuster in a direction in which adsorption of microorganisms in the treatment-object water to the carbon fiber is facilitated. As a result, the microorganisms are strongly attracted and adsorbed to the carbon fiber.
