Abstract

A method for controlling treatment of an industrial water system is disclosed. The method comprises the steps of providing an apparatus for controlling delivery of at least one treatment chemical, the apparatus comprising at least one sensor and an electronic input/output device carrying out a protocol; measuring a parameter of the industrial water system using the at least one sensor; relaying the measured parameter to the electronic device; adjusting the protocol based on the measured parameter; delivering a concentrated treatment chemical into a stream of the industrial water system according to the adjusted protocol, the concentrated treatment chemical comprising an active ingredient, the active ingredient traced as necessary, the active ingredient having a concentration; repeating the measuring, the adjusting, and the delivering; and optionally repeating the steps for n-number of parameters, n-number of active ingredients, and/or n-number of concentrated treatment chemicals.

First claim

1 - 14 . (canceled)

15 . A method of preparing an additive package having multiple active components, the method comprising:
dosing a volume of a first concentrated active ingredient comprising a first concentrated fluorophore into a solvent to form a first blend; monitoring a fluorescence response of the first concentrated fluorophore in the first blend to a first fluorometric set point sensitive to concentration changes; upon reaching the first fluorometric set point, dosing a volume of a second concentrated active ingredient into the first blend to form a second blend; and monitoring the fluorescence response of the first concentrated fluorophore in the second blend to a second fluorometric set point sensitive to concentration changes.

16 . The method of claim 15 , further comprising, upon reaching the second fluorometric set point, dosing a second volume of the first concentrated active ingredient comprising the first concentrated fluorophore into the second blend to form a third blend; and
monitoring the fluorescence response of the first concentrated fluorophore in the third blend to a third fluorometric set point sensitive to concentration changes.

17 . The method of claim 15 , further comprising, upon reaching the second fluorometric set point, dosing a third concentrated active ingredient into the second blend to form a third blend.

18 . The method of claim 17 , further comprising monitoring the fluorescence response of the first concentrated fluorophore in the third blend to a third fluorometric set point sensitive to concentration changes.

19 . The method of claim 18 , further comprising, upon reaching the third fluorometric set point, dosing a second volume of the first concentrated active ingredient comprising the first concentrated fluorophore into the third blend to form a fourth blend; and
monitoring the fluorescence response of the first concentrated fluorophore in the fourth blend to a fourth fluorometric set point sensitive to concentration changes.

20 . The method of claim 15 , wherein the first concentrated active ingredient and the first concentrated fluorophore are the same chemical.

21 . The method of claim 20 , wherein the first concentrated active ingredient and the first concentrated fluorophore are a corrosion inhibitor.

22 . The method of claim 21 , wherein the first concentrated active ingredient and the first concentrated fluorophore are poly acrylic acid tagged dispersant.

23 . The method of claim 15 , wherein the solvent comprises water.

24 . The method of claim 15 , wherein the second concentrated active ingredient comprises a second corrosion inhibitor.

25 . The method of claim 15 , wherein the first concentrated active ingredient comprises a corrosion inhibitor.

26 . The method of claim 25 , wherein the first concentrated fluorophore comprises an inert tracer.

27 . The method of claim 15 , w e second concentrated active ingredient comprises a scale inhibitor.

28 . The method of claim 15 , wherein the first concentrated active ingredient comprises a scale inhibitor.

29 . The method of claim 28 , wherein the first concentrated fluorophore comprises an inert tracer.

30 . The method of claim 19 , wherein the first concentrated active ingredient and the first concentrated fluorophore are the same chemical.

31 . The method of claim 30 , wherein the first concentrated active ingredient and the first concentrated fluorophore are a corrosion inhibitor.

32 . The method of claim 31 , wherein the first concentrated active ingredient and the first concentrated fluorophore are poly acrylic acid tagged dispersant.

33 . The method of claim 32 , wherein the second concentrated active ingredient comprises a second corrosion inhibitor.

34 . The method of claim 33 , wherein the third concentrated active ingredient comprises a scale inhibitor.
