Abstract

A water treatment solution may include a metal salt and a base product fluid. The base product fluid may include a molecular compound that is a chelating compound. The molecular compound may have the formula: ((NH 4 ) 2 SO 4 ) a .(H 2 SO 4 ) b .(H 2 O) c .(NH 4 HSO 4 ) x . In the formula, a may be between 1 and 5, b may be between 1 and 5, c may be between 1 and 5, and x may be between 1 and 10. The water treatment solution may be formed by adding the metal salt to the base product fluid and water. The water treatment solution may be added to water in need of treatment. The water in need of treatment may be a static body of water.

Claims (35)

1. A water treatment solution, comprising:

chelating compound having the formula:

((NH 4 ) 2 SO 4 ) a .(H 2 SO 4 ) b .(H 2 O) c .(NH 4 HSO 4 ) x ,

wherein a is between 1 and 5, b is between 1 and 5, c is between 1 and 5, and x is between 1 and 10;

a metal salt; and

water.

2. The chelating compound of claim 1 , wherein the metal salt comprising a salt of zinc, magnesium, manganese, selenium, molybdenum, iron, boron, cobalt, copper, or combinations thereof.

3. The chelating compound of claim 1 , wherein the chelating compound chelates the metal salt.

4. The solution of claim 1 , wherein the water treatment solution has a pH below about 2.

5. The solution of claim 1 , wherein the chelating compound comprises an elemental composition of:

between about 3% and about 6% hydrogen;

between about 10% and about 15% nitrogen;

between about 25% and about 30% sulfur; and

between about 52% and about 60% oxygen.

6. The solution of claim 1 , wherein a is 1, b is 1, c is 1, and x is between 1 and 6.

7. A method for making a water treatment solution, comprising:

adding a metal salt to a base product fluid and water, wherein the base product fluid comprises:

a chelating compound having the formula:

((NH 4 ) 2 SO 4 ) a .(H 2 SO 4 ) b .(H 2 O) c .(NH 4 HSO 4 ) x ,

wherein a is between 1 and 5, b is between 1 and 5, c is between 1 and 5, and x is between 1 and 10.

8. The chelating compound of claim 7 , wherein the metal salt comprises a salt of zinc, magnesium, manganese, selenium, molybdenum, iron, boron, cobalt, copper, or combinations thereof.

9. The chelating compound of claim 7 , wherein adding the metal salt to the chelating compound generates little to no heat.

10. The chelating compound of claim 7 , wherein the water treatment solution has a pH below about 2.

11. A method of treating water, comprising:

adding a water treatment solution to water in need of treatment, the water treatment solution comprising a metal salt and a chelating compound having the formula:

((NH 4 ) 2 SO 4 ) a .(H 2 SO 4 ) b .(H 2 O) c .(NH 4 HSO 4 ) x ,

wherein a is between 1 and 5, b is between 1 and 5, c is between 1 and 5, and x is between 1 and 10.

12. The method of claim 11 , wherein the metal salt comprises a salt of zinc, magnesium, manganese, selenium, molybdenum, iron, boron, cobalt, copper, or combinations thereof.

13. The method of claim 11 , wherein the water treatment solution controls nuisance mollusks in the water in need of treatment.

14. The method of claim 11 , wherein the water treatment solution removes taste and/or odors from the water in need of treatment, the water in need of treatment being drinking water.

15. The method of claim 11 , wherein the water treatment solution kills mosquitoes the water in need of treatment.

16. The method of claim 11 , wherein the water treatment solution controls bacteria in the water in need of treatment, the water in need of treatment being a swimming pool.

17. The method of claim 11 , wherein the water treatment solution is used as an algaecide in the water in need of treatment.

18. The method of claim 11 , wherein the water treatment solution removes microbes from the water in need of treatment.

19. The method of claim 11 , wherein the water in need of treatment comprises a static body of water.
