ABSTRACT:
In an apparatus for treating liquid with electromagnetic flux, one or more coils surrounding a liquid conducting pipe are excited by a switching circuit including a triode switch turned on and off in response to the voltage applied to the coil or coils in such a way that during each operative half cycle of the supply voltage a current is conducted through the coils during an initial portion of the half cycle and then at a substantial time before the end of the half cycle, the switch is turned to an open condition causing the current built up in the coils to be taken up by a series resonant circuit, formed by the inductance of the coil or coils an associated given capacitance and the power supply, to produce a ringing current in and a ringing voltage across each coil and consequent ringing electromagnetic flux in the liquid passing through the pipe. The apparatus may have either a half wave or full wave mode of operation. When two or more coils are used, preferably the fluxes produced by at least two of the coils move in opposite directions through the liquid.
