In this embodiment, Zener diodes are applied for the protection of circuit. The current flows suddenly when the voltage reversed to PN-junction is applied to diodes. Zener effect is to occur tunneling effect of quantum mechanics that electrons in p-type semiconductor pass through small holes of insulated regions as reverse voltage gets higher. The higher reverse voltage is applied, the wider tunnel will be. Therefore, the current increases, but the voltage remains unchanged. In summary, The Zener diode is a device to make constant voltage using the phenomenon that the voltage remains unchanged mentioned above.
The condenser of the voltage multiplying rectifier circuit unit 37 has characteristics that electrical charges are charged when DC current is applied, and the electrical charges are discharged when it connected with circuit having reversed voltage to that charged voltage. As these steps are repeated rapidly, AC current caused by the charging and discharging flows at both ends of the condenser.

For instance, an experiment shows a result that the efficiency is highest when the quantum field of 22KV, 1.64 MHz is scanned to wastewater including lots of non-biodegradable compounds of textile wastewater (Soluble Chemical Oxygen Demand increases 1.14 times and non-degradable materials are dualized). The another experiment shows a result that the efficiency is highest when the quantum field of 24KV, 1.64 MHz is scanned to wastewater including lots of non-biodegradable organic compounds of domestic wastewater(Soluble Chemical Oxygen Demand increases 2.25 times and non-degradable materials, which are difficult to degrade biologically, are dualized).

The reactor 200 comprises a diffuser for air bubbling 210 and an earth electrode 220. The high-frequency discharge electrode 51 comprises a protective cap 53.
When the apparatus for generating high frequency electromagnetic field 100 scans the extra high-frequency electromagnetic field which is suitable for contaminants and having range of 1 KHz to 400 MHz and the diffuser 210 bubbles airs in wastewater including various kinds of non-biodegradable compounds, anions and cations are dissociated, maintaining an eletro-equilibrium.
Therefore, hydrated organic compounds and complex ions of heavy metals are separated from hydration layer, and gas like reaction occurs in the water by these compounds and ions. In this condition, dissociation and ionization of contaminants are accelerated when polar organic molecules are escaped from the hydration layer by aeration using external underwater fan. It is because organic matters, complex ions, anions and cations are activated to higher energy level as V.O.C is oxidized and decomposed in the air in an instant.
Furthermore, the organic combined insoluble Phosphorus which is difficult to be decomposed is mineralized into ortho form and transforming soluble sludge, it makes easier to treat. Moreover, the water purification system nitrifies by converting Nitrogen to Proteins, and emits in the form of gas.
This present invention activates dissociation and ionization of contaminants by varying frequency and voltage to be suitable for contaminants to adjust quantum field intensity.

Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
