Patent number: 10139385Abstract: The invention provides methods and compositions for utilizing encapsulated tracer dyes in difficult liquids such as wastewater or with highly reactive treatment chemicals such as aluminum-based coagulants. In difficult liquids or highly reactive treatment chemicals even so-called “inert” tracers end up reacting and their fluorescence changes. As a result they are inconsistent and cannot be used to measure the amount of treatment chemical present.
