ABSTRACT:
An electrolysis water purification system employs a fixed magnitude ionization current source the output of which is effectively pulse-width modulated, by controlled switching of the connection of the current source to the ionizing electrodes. As a consequence, ion production can be controlled as a percentage of water flow time (the period during which the filtration pump is operating) and is evenly distributed throughout the water to be purified. The output of a DC power supply is coupled through a controlled switching circuit to the ionizing electrodes. The controlled switching circuit includes a presettable timer-controlled switch that operates under the control of clock generator and establishes the duty cycle of the supply of ionizing current to the electrodes. The output of the presettable timer-controlled switch is coupled through a timer-controlled polarity reversing circuit to the ionizing electrodes. The polarity reversing circuit serves to periodically reverse the current flow through the ionizing electrodes to ensure uniform wear of the electrodes and automatic cleaning of the deposits off the electrodes.
