A method, device, and system for treating water solutions is disclosed for the purpose of preventing the formation of deposits on the inner surface of pipelines, boilers and other equipment. The method is based on the use of radio waves which are sent in batches of four pulses, either of equal amplitude or with larger amplitude of the first pulse and smaller the last. Different hatches have different interval between pulses. The water treatment system disclosed which is based on the method; it significantly improves a water solution's properties without extensive usage of chemicals.

A method and system for utilizing electromagnetic energy of a frequency, and/or multiple frequencies, and higher harmonics of those frequencies to disrupt the normal bonding of the fluid molecules and that of mineral structures within the body of the fluid is disclosed. Electromagnetic signals at a frequency, frequencies, and higher harmonics related to the energy absorption/emission profile of the fluid being treated are directed into the fluid through direct or indirect injection and/or induced coupling. The frequency, frequencies, and higher harmonics of the treatment signal, preferably between 0.1 KHz and 1000 MHz, may be changed if the absorption/emission profile of the fluid changes during treatment.
