Claims18
A method for treating water using an electromagnetic field, the method comprising:
- subjecting the water to the electromagnetic field generated utilising an inductor coil;
- and
- varying a frequency of a driving signal for the inductor coil such that the generated electromagnetic field has a varying frequency, wherein the frequency is varied over a range between about 100 kHz and about 500 kHz.
A system for treating water using an electromagnetic field, the system comprising:
- an inductor coil for subjecting the water to the electromagnetic field;
- a driver unit coupled to the inductor coil;
- and
- a controller unit coupled to the driver unit for varying a frequency of a driving signal generated by the driver unit such that the generated electromagnetic field has a varying frequency, wherein the frequency is between about 100 kHz and about 500 kHz.
