CONTROL SYSTEM FOR THE PROCESS OF ELECTROEROSION WATER PURIFICATION

Abstract

Purification of natural and industrial wastewater from harmful impurities is an urgent task. Classical methods of water purification have a number of disadvantages: high consumption of reagents; the need for periodic replacement of membranes; high cost of membranes and reagents; large areas are required to accommodate equipment; the inability to effectively purify water sources from toxic substances and dissolved salts. Recently, the use of electric energy for water purification, including electroerosive water purification, has been of particular interest. Management systems are being developed to manage and improve the efficiency of the cleaning process. The control system developed in the article is based on a nonlinear model of the process of electroerosive water purification. The linearization of the model made it possible to create a control system with PID regulation.
