Abstract
A method and apparatus for controlling the production of a haloamine biocide based on direct, in-process, measurement of the oxidant content to produce a desired haloamine biocide for the control of growth of microorganisms in aqueous systems, particularly in industrial water systems, is provided.
Claims20
A method of producing a haloamine biocide having predetermined actives comprising:
- a) providing a source of water, an oxidant and an amine;
- b) measuring the oxidant concentration prior to combining the oxidant with the amine;
- wherein the measured oxidant concentration is input or otherwise entered into a programmable logic controller along with the concentration of amine and the predetermined or desired actives of the produced haloamine biocide;
- and wherein based on the measured oxidant concentration and amine concentration the programmable logic controller calculates the amount of water, oxidant and amine required to produce the haloamine biocide having the predetermined actives;
- c) contacting the water, oxidant and amine in amounts calculated by the programmable logic controller to produce the haloamine biocide having the predetermined actives.
An apparatus for the direct in-line preparation of a haloamine biocide having predetermined actives comprising:
- a) a probe for the direct measurement of the oxidant concentration,
- b) a programmable logic controller, wherein a measured oxidant concentration, amine reagent concentration, and predetermined actives of desired haloamine biocide are entered into the programmable logic controller;
- c) a pump P1, capable of delivering a controlled amount of water;
- d) a pump P2, capable of delivering a controlled amount of an oxidant;
- and
- e) a pump P3, capable of delivering a controlled amount of an amine reagent;
- wherein the water, oxidant and amine are combined to produce the haloamine biocide having the predetermined actives.
A method for controlling the growth of microorganisms in aqueous systems using a haloamine biocide comprising:
- a. providing a source of water, an oxidant and an amine;
- b. measuring the oxidant concentration prior to combining the oxidant with the amine;
- wherein the measured oxidant concentration is input or otherwise entered into a programmable logic controller along with the concentration of the amine and a predetermined or desired actives of the produced haloamine biocide;
- and wherein based on the measured oxidant concentration and amine concentration, the programmable logic controller calculates the amount of water, oxidant and amine required to produce a haloamine biocide having the predetermined actives;
- c. contacting the water, oxidant and amine in amounts calculated by the programmable logic controller to produce the haloamine biocide having the predetermined actives;
- and
- d. adding the produced haloamine biocide to the aqueous system.
