ABSTRACT
There is no question as to whether or not it is necessary to monitor processes and speci c chemicals in various water treatment applications. The question normally is which parameters of the treated water should be monitored continuously, which parameters should be monitored on a regular basis, and which parameters should be monitored only occasionally. To answer this question, each customer or water treater should fully understand the treatment process and the application specifics, because sometimes the monitoring of the same parameter results in completely different conclusions. Some applications require different chemicals to address the speci c needs of the equipment and/or to achieve speci c goals. Once the treatment agent is chosen, the next big task is to establish the right protocol for its monitoring.
