Abstract
Abstract This invention describes a novel scale and corrosion prevention and removal method and means for water systems, wherein alternating current fields are applied to the water at predetermined prime number frequencies to condition the water electrically which results in the breakup of ionic components in the water, usually responsive for corrosion and scale formation, thereby preventing the development of scale or corrosion in the water system plumbing and, in effect, dissolving scale and corrosion which may already be present.

Claim 1
Independent Claim
235 words
A water conditioning system comprising: a polarity-reversing pulse generator having output poles providing a polarity-reversing electric current having a predetermined prime number frequency; a water-conditioning cell; a central electrode in said cell capacitively coupled to a terminal therein, said terminal being connected by conductive means to one polar output of said polarity-reversing pulse generator; a filter electrode concentric with said central electrode insulated from and spaced apart from said central electrode, said filter electrode being connected by conductive means to the other pole of the output of said pulse generator; and a housing concentrically enclosing said filter electrode and spaced apart and insulated therefrom, said housing being closed at one end and having an inlet communicating with the space between said central electrode and said filter electrode, and an outlet communicating with said space between said filter electrode and said housing, whereby water entering said water-conditioning cell through said inlet is passed between said central electrode and said filter electrode and there is subjected to the field of said polarityreversing electric current wherein the water molecules are polarized and any ionizable substances therein are ionized, said water passing through said filter electrode into said space between said filter electrode and said housing and through said outlet to a user medium, the water being conditioned in its passage through the water-conditioning cell by the ionization of all ionizable molecules therein so that they remain in solution.
