Abstract
The present invention is a method of treating a standing water system comprising the administration to the standing water system of an admixture comprising calcium hypochlorite and borate salts. The method of treating a standing water system provides free chlorine to the system more efficiently than prior art methods, stabilizes the pH of the standing water system, and reduces the undesired side effects of the addition of calcium hypochlorite alone.
Claims
1. A method of reducing microbial growth in a standing water system comprising the administration of an admixture comprising an effective amount of calcium hypochlorite and an effective amount of a mixture comprising borate salt and boric acid.
2. The method of Claim 1 wherein the admixture is administered to the standing water system so that the final concentration of the admixture is between approximately 0.5 and 10 pounds per 10,000 gallons of water.
3. The method of Claim 2 wherein the concentration of the admixture in the standing water system is between approximately 1 and 5 pounds per 10,000 gallons of water.
4. The method of Claim 1 wherein the borate salt comprises, sodium tetraborate pentahydrate, sodium tetraborate octahydrate, sodium tetraborate decahydrate, lithium tetraborate pentahydrate, or potassium tetraborate octahydrate.
5. The method of Claim 4 wherein the borate salt is sodium tetraborate octahydrate.
6. The method of Claim 4 wherein the borate salt is a mixture of sodium pentaborate and boric acid.
7. The method of Claim 1 wherein the calcium hypochlorite in the admixture is between approximately 60% and 80% by weight.
8. A method of reducing calcification of a water filter of a standing water system, comprising the administration of an admixture comprising an effective amount of calcium hypochlorite and an effective amount of a borate salt.
9. The method of Claim 8 wherein the admixture is administered to the standing water system so that the final concentration of the admixture is between approximately 0.5 and 10 pounds per 10,000 gallons of water.
10. The method of Claim 9 wherein the concentration of the admixture in the standing water system is between approximately 1 and 5 pounds per 10,000 gallons of water.
1 1. The method of Claim 8 wherein the borate salt comprises, sodium tetraborate pentahydrate, sodium tetraborate octahydrate, sodium tetraborate decahydrate, lithium tetraborate pentahydrate, or potassium tetraborate octahydrate.
12. The method of Claim 8 wherein the borate salt is sodium tetraborate octahydrate.
13. The method of Claim 8 wherein the borate salt is sodium pentaborate and the admixture further comprises boric acid.
14. The method of Claim 8 wherein the calcium hypochlorite in the admixture is between approximately 60% and 80% by weight.
15. A method of stabilizing the pH of a standing water system, comprising the administration of an admixture comprising an effective amount of calcium hypochlorite and an effective amount of a borate salt.
16. The method of Claim 15 wherein the admixture is administered to the standing water system so that the final concentration of the admixture is between approximately 0.5 and 10 pounds per 10,000 gallons of water.
17. The method of Claim 16 wherein the concentration of the admixture in the standing water system is between approximately 1 and 5 pounds per 10,000 gallons of water.
18. The method of Claim 15 wherein the borate salt comprises, sodium tetraborate pentahydrate, sodium tetraborate octahydrate, sodium tetraborate decahydrate, lithium tetraborate pentahydrate, or potassium tetraborate octahydrate.
19. The method of Claim 15 wherein the borate salt is sodium tetraborate octahydrate.
20. The method of Claim 15 wherein the calcium hypochlorite in the admixture is between approximately 60% and 80% by weight.
