ABSTRACT:
This invention involves a water and fuel conditioning technique using a copper based composition to treat water or fuel flowing through a device for the purpose of minimizing scale formation and reducing emissions.
BACKGROUND OF THE INVENTION
It is known in the art to use a copper based composition to treat water to minimize or eliminate scale formation and to treat fuel for one of several advantages. A different mechanism must be operating because some compositions which are effective for fuel treatment are not effective for water treatment, and vice versa.
Copper based compositions in the form of a casting are known to create catalytic changes in water and fuel flowing in contact with the casting. Disclosures of such compositions are found in U.S. Pat. Nos. 4,715,325; 4,789,031; 4,820,422; 4,959,155; 5,013,450; 5,197,446; 5,204,006; 5,470,462; and 5,814,227.
SUMMARY OF THE INVENTION
In this invention, a composition having 40-60% copper, 2-30% zinc, 10-25% nickel, 2-5% tin, all percentages being by weight, and trace amounts, if any, of iron and lead, produce exaggerated electrical changes in water passing around the composition. Water flowing around a mass of the composition of this invention produces a higher voltage response than water flowing around a mass of known similar water treating compositions which are conceded to be effective in reducing scale and providing other advantages.
Most of the literature fails to explain why the prior art compositions are effective and, at first exposure, one is skeptical they actually work. As will be shown hereinafter, objective tests show that water flowing in contact with appropriate metal compounds have different electrical properties, depending on the composition of the metal compounds. While not being bound by any theory of operation, it appears the increased electrical charges in water flowing through this invention minimizes the deposition of scale precursors in piping. It appears that typical scale, largely calcium carbonate, does not deposit well on the interior of piping until a precursor, mainly phosphates, is deposited. After the precursor deposits on the interior of piping, calcium carbonate based scale readily deposits. Potable water supplied by municipalities is normally electron deficient and not in optimum states of equilibrium. Colloids in the water are also electron deficient and are drawn, by electrostatic attraction, to metals in the plumbing system and accumulate as scale.
The device of this invention provides a source of electrons. When water is run through a device of this invention, electrons are provided to reduce or eliminate the electron deficiency. The bonds holding scale to the walls of plumbing components weakens and allows the scale to break up by adding electrons in a catalytic manner. Water treated by this invention thus prevents new scale deposits, tends to remove old scale deposits from plumbing components and provides other advantages.
The same composition is also effective as a fuel conditioner as will be shown hereinafter by tests. In addition to improved effectiveness, a major advantage is the reduction of lead in the composition thereby minimizing or eliminating releasing lead into the fuel and thereby into the environment.
It is an object of this invention to provide an improved water conditioning device comprising copper, zinc, nickel and tin and having only trace amounts, if any, of lead.
A further object of this invention is to provide a method of conditioning water by passing the water in contact with a metal mass comprising copper, zinc, nickel and tin, and having only trace amounts, if any, of lead.
Another object of this invention is to provide an improved fuel conditioning device comprising copper, zinc, nickel and tin and having only trace amounts, if any, of lead.
These and other objects and advantages of this invention will become more apparent as this description proceeds, reference being made to the accompanying drawings and appended claims.
