Patent ID: 7524413

Claim:
An apparatus for treating a fluid with electromagnetic fields, said apparatus comprises: (A) a treatment zone having a non-metallic conduit through which said fluid flows: (B) a power supply; (C) a signal generator having: (i) at least one switch; (ii) a first controller, said first controller operates said switch; and (iii) a first power source fed by said power supply for supplying power to said switch; (D) at least one high frequency induction coil, said high frequency induction coil surrounds a section of said conduit and provides a high frequency electromagnetic field into said treatment zone in sufficient strength and for a sufficient exposure time to treat contaminants in said fluid; (E) a second controller, said second controller includes two diodes, each of said diodes switches an alternate half of applied supply voltage; (F) a second power source fed by said power supply, said second power source includes a transformer; and (G) at least two low frequency induction coils, said low frequency induction coils surround a section of said conduit and provide a low frequency electromagnetic field in said treatment zone in sufficient strength and for sufficient exposure time to treat contaminants in said fluid.
