Abstract

Source water is treated by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers, and mixtures thereof, a second component from the group comprising chlorite salt and chlorate salt is admixed to the mixture of the water and the first component, and water. The water and the first and second components are present in amounts sufficient to form a stable liquid composition in which there is substantially no conversion of the second component to chlorine dioxide.

Claims

1. A disinfecting/mineral treating composition formed by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers, and mixtures thereof, a second component from the group comprising chlorite salt and chlorate salt and water;

wherein the water and the first and second components are present in amounts sufficient to form a stable liquid composition in which there is substantially no conversion of the second component to chlorine dioxide.

2. The composition of claim 1, having a pH of 7.0 or higher.

3. The composition of claim 1, in which the first component is neutralized to a pH of at least about 7.0 before mixing second component to the first component.

4. The composition of claim 1, wherein the second component is sodium chlorite.

5. The composition of claim 4, wherein the second component is an about 1% to about 25% solution of sodium chlorite.

6. A composition formed by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus and anti-scalent polymer, and mixtures thereof, water, a second component from the group comprising chlorite salt and chlorate salt, water and;

wherein the pH of the first component is adjusted to be substantially about 8.5 before the second component is admixed with the first component.

7. A composition formed by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, anti-scalent polymers, and mixtures thereof, second component from the group comprising chlorite salt and chlorate salt, and water;

wherein the first component is neutralized to a pH of substantially 7.0 before the second component is admixed with the first component.

8. A method of forming distorted mineral deposits on a surface, comprising:

mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers and mixtures thereof, a second component from the group comprising chlorite salt and chlorate salt, and water;

wherein the first and second components are present in amounts sufficient to form a stable composition in which there is substantially no conversion of the second component to chlorine dioxide;

and applying the disinfecting composition to the surface and cause mineral deposits to become amorphous.

9. The method of claim 8, further comprising washing the amorphous mineral deposits from the surface.

10. A method of disinfecting a surface, comprising:

mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers and mixtures thereof, and a second component from the group comprising chlorite salt and chlorate salt, and water;

wherein the first and second components are present in amounts sufficient to form a stable composition in which there is substantially no conversion of the second component to chlorine dioxide; and

applying the composition to a surface to remove microorganisms from the surface.

11. The method of claim 10, wherein the second component is an about 1% to about 25% sodium chlorite.
