ABSTRACT:
The invention provides a process and apparatus for improving the quality of water in an easy manner and with reasonable cost and high efficiency. The process provides a grounding electrode and a pair of applying electrodes in water to be treated. First and second high-frequency switches are connected respectively to a DC voltages source through a variable resistor. A switching commander circuit, which is a flip-flop circuit, is connected to the first and second switches through a resistor. An oscillator is connected to the switching commander circuit. The switching commander circuit alternately outputs a switching command to the first and second switches, in response to a signal from the oscillator, so that the first and second switches are periodically turned ON and OFF resulting in voltage being alternately applied to the pair of applying electrodes which causes an ORP value of the water to decrease.
