Abstract
The invention comprises an apparatus for optimizing the dosage of a chemical waste water treatment agent using a fluorescent tracer by processing a sample of the waste water stream and allowing continuous on-stream monitoring of the performance of the chemical waste water treatment agent. The apparatus is comprised of a series of components that sample the waste stream, process the sample for analysis, analyze the sample, record the data in a historical database and, based upon the analysis as compared to historical data, adjust the chemical feed system to optimize the chemical waste water treatment agent according to the programmed optimization logic.
