METHOD FOR PRODUCING A STABLE OXIDIZING BIOCIDE
The invention relates to a production method for producing stable chloramine. The method allows for the production of stable chloramine with the use of concentrated chlorine source and concentrated amine source and agitation during production. The method produces a chloramine that has a pH of at least 5 with a most preferred pH of at least 7 or greater.
1 . A method for producing a stable chloramine in a continuous flow wherein a concentrated chlorine source is combined at ambient temperature with a concentrated amine source at ambient temperature and is agitated to produce a stable chloramine with a pH of 7 to 10.5.
2 . The method of claim 1 wherein the chlorine source contains an alkali earth metal hydroxide.
3 . The method of claim 1 wherein the amine source is ammonium sulfate.
4 . The method of claim 1 wherein the amine source is ammonium hydroxide.
5 . The method of claim 1 molar ratio of chlorine source to amine source is 1:0.755 to 1:6 and more preferably 1:0.755 to 1:2.
6 . The method of claim 1 molar ratio of chlorine source to amine source is 1:0.755 to 1:2.
7 . The method of claim 6 wherein the reaction medium is a liquid.
8 . The method of claim 6 wherein hydroxide levels are increased.
9 . The method of claim 1 wherein the stable chloramine has a pH of 8 to 10.
10 . The method of claim 2 wherein the chlorine source is sodium hypochlorite or calcium hypochlorite.
11 . A method for producing a stable chloramine wherein a concentrated chlorine source is combined with a concentrated amine source with a reaction medium and is agitated to produce a stable chloramine with a pH of 7 to 10.5.
12 . The method of claim 11 wherein the chlorine source contains an alkali earth metal hydroxide.
13 . The method of claim 12 wherein the chlorine source is sodium hypochlorite or calcium hypochlorite.
14 . The method of claim 11 wherein the amine source is ammonium sulfate.
15 . The method of claim 11 wherein the amine source is ammonium hydroxide.
16 . The method of claim 11 wherein the reaction medium is a liquid.
17 . The method of claim 16 wherein the reaction medium is water.
