Claims
- 1. A composition for inhibiting the growth of microorganisms comprising effective amounts of peracetic acid and a non-oxidizing biocide selected from the group consisting of benzisothiazolin, carbonimidic dibromide, 1,4-Bis(bromoacetoxy)-2-butene and .beta.-bromo-.beta.-nitrostyrene.
- 2. The composition of claim 1 wherein the amount of peracetic acid ranges from about 10 to about 250 ppm and the amount of the non-oxidizing biocide ranges from about 1 to about 250 ppm.
- 3. A method for controlling the growth of microorganisms in industrial process water comprising the step of administering a sufficient amount of peracetic acid and a sufficient amount of a non-oxidizing biocide selected from the group consisting of benzisothiazolin, carbonimidic dibromide, 1,4-Bis(bromoacetoxy)-2-butene and .beta.-bromo-.beta.-nitrostyrene to the industrial process water to inhibit the growth of the microorganisms.
- 4. The method of claim 3 wherein the industrial process water is selected from the group consisting of water of a pulp and paper mill system, cooling water and mining water.
- 5. The method of claim 3 wherein the peracetic acid and the non-oxidizing biocide are added in a ratio from about 250:1 to about 1:25.
- 6. The method of claim 3 wherein the amount of peracetic acid added ranges from about 10 to about 250 ppm and the amount of the non-oxidizing biocide ranges from about 1 to about 250 ppm.
- 7. The method of claim 3 wherein the microorganisms contain bacteria.
- 8. The method of claim 3 wherein the microorganisms contain fungi.
- 9. The method of claim 3 wherein the peracetic acid is added to the industrial water prior to the addition of the non-oxidizing biocide.
