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.
