  • Patent number: 6818417
    Abstract: A method for locating hidden microorganism contaminated surfaces in industrial water systems is described and claimed. The method works by applying a solution or dispersion of a fluorogenic reagent in water to the hidden water contact surfaces of said industrial water system and allowing said fluorogenic reagent to react with any hidden microorganisms present, wherein said fluorogenic reagent is selected from the group of fluorogenic reagents that are known to react with microorganisms such that a fluorescent signal of said fluorogenic reagent is detectable in such a way as to make the detection of the fluorescent signal indicate that there are hidden microorganisms present on the water contact surfaces of the equipment and piping.

  • Patent number: 6685840
    Abstract: A method of making a solid water treatment product with an optimal rate of dissolution is described and claimed. A fluorescent tracer is used to determine the rate of dissolution of the solid water treatment product and the composition and method of manufacturing the solid water treatment product are adjusted as needed to make the rate of dissolution optimal. The solid water treatment product can be used in many industrial water treatment systems. When the solid water treatment product is used, the amount of solid water treatment product present in the water of the industrial water system can be determined, and adjusted, by using a fluorometer to measure the fluorescent signal of the fluorescent tracer present in the product and relating that measurement to the amount of product in the water itself.
