Automated monitoring system for quality of treated wastewater from a power plant by incorporating flow injection analysis

摘要

An automated monitoring system for quality of treated wastewater from a power plant by incorporating flow injection analysis (FIA) has been developed. Measurements for pH, conductivity, dissolved oxygen, and water level are made by using sensors/probes. The FIA procedures are for sulfate, phosphate, and iron. The online monitoring system accommodated in a hut, at the sampling site, 10 km from the control station, is automatically operated by making use of process logic control. The central control station links to the monitoring instruments via a mobile radio set for control of the instrument operation and data acquisition and evaluation. © 2000 John Wiley & Sons, Inc.
