  • Enhancement of the efficacy of antimicrobials by the addition of anions capable of interfering with microbial electrochemical reactions
    Patent number: 4995987
    Abstract: A method of enhancing the efficacy of anti-microbial chemical compounds in an aqueous medium comprising adding an anionic chemical species to the medium. The anion acts as a competing electron receptor of the terminal cellular reduction reaction. This results in a weakening of the microorganism leaving it more vulnerable to effective action by the anti-microbial chemical.

  • Apparatus and process for feeding hypochlorite solution
    Patent number: 4818412
    Abstract: An improved apparatus and process for feeding hypochlorite solution from a source of the solution to a device for removing impurities from water in a water treatment system is disclosed. The improvement comprises a first means for continuously measuring the oxidation/reduction potential of the effluent water of the device, and a second means operatively connected to the first means and the pump means continuously controlling the feed-rate of the pump means in response to the measured oxidation/reduction potential of the effluent water, thereby maintaining a predetermined oxidation/reduction potential in the effluent water of the device.
