ABSTRACT

The model of the electrocoagulator, which describes the processes taking place in the electrolyzer,The model of the electrocoagulator, which describes the processes taking place in the electrolyzer,was developed. The solution of the corresponding model problem was found. The effect ofcurrent strength on the concentration of divalent iron, water temperature was investigated. The algorithmof the two-circuit regulation of pollution concentration in sewage with feedback bonds ofcurrent between the plates of the coagulator and the concentration of pollution in water arriving inthe automated system of purification is developed. A functional scheme of automation with 5contours of regulation and a selected set of technical means of automation of leading manufacturersof companies was constructed. An automated control system of wastewater treatment was developedwith the implementation of a coagulant prediction algorithm in relation to the input pollutionconcentration. It was implemented to control the current strength in the electrolyzer withminimal electricity consumption. Assumed management system with the ability to change the entireperformance settings in real time using SCADA - system WinCC Flexible.
