The tele-monitoring system (TMS) refers to a system that monitors the emission state of pollutants on a 24-hour basis by online-connecting a remote water quality control center with automatic measurement devicesattached to the discharging outlets of wastewater processing facilities and wastewater-producing businesses. The core of the TMS is the reliability of data from the continuous water monitoring equipment (CWME). Thedata reliability depends upon the accuracy and uniformity of the monitoring equipment as well as the representativenessof samples. The water sampling system is a major factor affecting the measuring resultsbecause it consists of a series of continuous sample collection processes from the effluent outlet to the CWME. Experiments were performed with a specially designed sampling system. The mixing characteristics of eachsample in the designed system were investigated using three-dimensional computational analyses of fluid andtracer tests. In addition, the residence time distribution (RTD) and the dispersion number were analyzed. Theresults showed that the sampling system is applicable as a standard of performance test for sampling baths.
