Method for treating water
A composition for treating water contained in enclosures, such as swimming pools, spas, whirlpool tubs and cooling towers, which includes at least one boron compound, cyanuric acid, at least one mineral remover and at least one clarifier is provided. A composition and method for treating salt water contained in enclosures using halogen generators to generate sterilizing halogen in situ, wherein the method includes adding to the water effective amounts of a composition having at least one boron compound, cyanuric acid, at least one mineral remover and at least one clarifier, such that they are present in the water simultaneously is also provided.
1. A method for treating water contained in an enclosure which uses halogen generators including metal electrolytic plates to generate sterilizing halogen in situ, comprising the steps of:
providing a composition comprising:
at least one boron compound;
cyanuric acid;
at least one mineral remover; and
at least one clarifier;
adding to the water effective amounts of the composition such that the at least one boron compound, cyanuric acid, at least one mineral remover, and at least one clarifier are present in the water simultaneously, to inhibit bacteria, algae, and fungal growth, and wherein said boron compound protects said metal electrolytic plates from corrosion.
2. The method for treating water of claim 1 , wherein the composition comprises:
from about 56% to about 94% of at least one boron compound;
from about 5% to about 30% cyanuric acid;
from about 1% to about 3% of at least one mineral remover; and
from about 0.1% to about 0.3% of at least one clarifier.
3. The method for treating water of claim 2 , wherein the at least one boron compound comprises boric acid and sodium tetraborate pentahydrate, and wherein the ratio of boric acid to sodium tetraborate pentahydrate is about 1:1 to about 4:1.
4. The method for treating water of claim 3 , wherein the at least one mineral remover comprises 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) and the at least one clarifier comprises dimethyl diallyl ammonium chloride (DMDAAC).
5. The method for treating water of claim 1 , wherein the composition comprises:
from about 43% to about 74% boric acid;
from about 13% to about 44% sodium tetraborate, pentahydrate;
from about 5% to about 30% cyanuric acid;
from about 1% to about 3% HEDP; and
from about 0.1% to about 0.3% DMDAAC.
6. The method for treating water of claim 5 , wherein the composition comprises:
from about 65% to about 74% boric acid;
from about 13% to about 20% sodium tetraborate, pentahydrate;
from about 8% to about 12% cyanuric acid;
from about 1% to about 3% HEDP; and
from about 0.1% to about 0.3% DMDAAC.
7. The method for treating water of claim 1 , further comprising the step of treating the water to a pH of about 7.2 to about 7.6.
8. The method of treating water of claim 1 , further comprising the step of treating the water to a concentration of:
about 30 ppm to about 50 ppm boron;
about 20 ppm to about 80 ppm cyanuric acid;
about 3 ppm to about 9 ppm mineral remover; and
about 0.03 ppm to about 0.09 ppm clarifier.
9. The method of treating water of claim 8 , wherein the concentration of cyanuric acid is about 30 ppm to about 50 ppm.
