ABSTRACT:
The invention comprises a method of determining the concentration of a water soluble polymeric treating agent added to wastewater treatment system. The method comprises several steps including dosing the body of water with a predetermined concentration of a treating agent having a fluorescent tag covalently bonded to the treating agent, removing a sample of the water containing the tagged treating agent, analyzing the emissivity of the sample to measure the concentration of the treating agent in the sample and adjusting the concentration of the treating agent accordingly to fit within a predetermined concentration range.
