Automation of the technological processes of wastewater treatment: case study of the Minsk wastewater treatment plant of UE Minskvodokanal

Summary

The experience of UE Minskvodokanal in developing and establishing of automated control systems for the technological process of wastewater treatment is presented using the example of several structures of the Minsk wastewater treatment plant. The goals and tasks performed by the automated process control systems at the plant are described. The structure and operating modes of the implemented systems are presented. The stages of the wastewater treatment process are considered in detail: screening, sand removing and processing, supplying and distributing air across sections of the aeration tanks. As part of the automation of the presented treatment stages, the general design of the automated process control system is described, the operating features, the objects used and automation modes are given. Special attention is paid to the need for simple and reliable control algorithms. The ultimate goal of upgrading the automated process control system of the Minsk wastewater treatment plant is the maximum degree of automation and supervisory control covering the entire technological chain of wastewater and sludge treatment based on the simple and reliable principles.
