ABSTRACT:
A water purification system including a constant current electrical control system for providing a constant electric current between an anode and cathode in contaminated variable resistance water flowing between the anode and cathode, and a filtering system to remove the clustered particles after the water passes between the cathode and anode. The anode is encircled by a cathode screen with a fluid flow pattern between the anode and cathode to aid the function of the constant current system. In the preferred embodiment, the constant electric current between the anode and cathode is provided by an electrical circuit having an adjustable voltage regulator with the output of the regulator connected to the drain of a Field Effect Transistor, F.E.T., and with the control terminal of the voltage regulator connected to the source of the F.E.T. In addition, the source of the F.E.T. is connected to the anode of the device and the gate of the F.E.T. is electrically biased by a resistor bridge between the drain and the source of the F.E.T. so that the F.E.T. is "on" in a saturated mode.
