Electric treatment and regulation of biotoxic properties of drilling waters

Abstract

Well drilling is accompanied by the formation of significant volumes of water that contain mechanical and biological impurities. The purpose of the work is to investigate the possibility of regulating the biological properties of drilling and other types of water that using the technologies of electrical processing (electrooxidation). The analysis of methods and technologies for the disinfection of aqueous solutions and emulsions is carried out. The process of electrooxidation of bacteria in contact with the surface of the electrode plates is considered. The determination of the electrokinetic charge of the surface of particles (bacteria) is carried out, which must be taken into account when calculating the processes and equipment for the electrooxidation of bacteria in technological aqueous solutions such as emulsions. The processes of electrooxidation of aqueous emulsions such as Ukrinol and Triethanolamine which are widely used in cutting, grinding, etc., are considered. Physical and mathematical models of disinfection processes at different values of electric current and surface area of oxidizing electrodes are studied. The factors influencing the disinfection process have been determined. Conceptual approaches to the creation of electrooxidizing devices for the disinfection of emulsions directly in the channels through which aqueous technological solutions move are proposed. Aspects of practical application of electrooxidation technology are considered.
