The aim of the study is to develop a technology for the treatment of industrial wastewater by means of a pressure flotation unit. The modernized unit of pressure flotation with various feed of water-air mixture was designed and constructed on the basis of the review of scientific and technical literature. The tests with different variations in the supply of water-air mixture to the unit were carried out in order to improve the quality of treated wastewater and, as a result, to the reduction of environmental damage. We carried out a comparative analysis of each variant in terms of the quality of treated industrial waste water and we identified the most appropriate variant for various technological treatment schemes. All results of the research considered we offer the automation of this device. The purpose of automation of the pressure flotation unit was to increase the efficiency of the used equipment, to maintain the stability of the unit, to obtain information on all the processes of industrial wastewater treatment, as well as to prevent an emergency situation.
