Monitoring and controlling of process parameters in the biological phase of wastewater treatment

This article presents the methodology for monitoring and controlling the process parameters of the biological stage of wastewater treatment, through the monitoring, control, and data acquisition program SCADA. The introduction of the SCADA software in the field of wastewater treatment has appeared with the evolution of treatment technologies and increasing legal requirements for the quality of emissions. The implementation of this program brings significant benefits to wastewater treatment plants and facilitates the control and monitoring of the technological process in the wastewater treatment plant. By using this software, the cost of energy consumption can be reduced, the operating time of a treatment plant equipment can be tracked, time faults of the installations can be detected in the treatment plant, can be drawn up working graphs and tables with data from technological process etc. The present study highlights the kinetics of the treatment process in the biological treatment stage of the Iași City Wastewater Treatment Plant and the usefulness of the research performed.
