ABSTRACT:
The invention provides a process and apparatus for treating water, which can be stably operated with high efficiency over a long period of time. The apparatus has a grounding electrode and a pair of applying electrodes connected to a DC voltage source through a register and first and second high-frequency switches which are controlled by a high-frequency switching commander circuit, to convert DC voltage from the DC voltage source to AC voltage to be fed to the applying electrodes. The high-frequency switching commander circuit is connected to a first high-frequency oscillation circuit connected to a control circuit which is controlled by a second high-frequency oscillation circuit, to provide a signal changing randomly in frequency as output signal from the first high-frequency oscillation circuit. The second high-frequency oscillation circuit also controls a flip-flop circuit connected to the first high-frequency oscillation circuit, to add acutely and momentary frequency fluctuating portions in randomly frequency changing signal from the first oscillation circuit.
