Patent ID: 7981288

Claim:
An apparatus for treating a fluid with electromagnetic fields, said apparatus comprises: (A) a treatment zone having a conduit through which said fluid flows: (B) an AC 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 AC power supply for supplying power to said switch; (D) at least one high frequency induction coil energized at a frequency of between 10,000 and 100,000 Hz, 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 AC power supply, said second power source includes a transformer; and (G) at least two lower frequency induction coils energized at a frequency generated by said AC power supply, said lower frequency induction coils surround a section of said conduit and provide a lower frequency electromagnetic field in said treatment zone in sufficient strength and for sufficient exposure time to treat contaminants in said fluid.
