“…The removal mechanism and approach of microorganisms and the design principles of integrated recycling equipment are outlined. The scientific work [11] indicates the types of bacteria that were detected in both used MWF sump and mist samples. These included Ochrobactrum and Proprionibacterium at site visit one, and Methylobacterium at site visit two.…”

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.

“…However, neither Crook and Swan (182) nor any other authors reported any possible relationship between endotoxin bioaerosol concentration or connected adverse health effects among exposed workers. Consequently, a relationship between MWF bioburden and endotoxin bioaerosol concentration, as well as between endotoxin bioaerosol concentration and respiratory disease in the metalworking environment, remains speculative (183,184).…”

Water-miscible metalworking fluids (MWFs) are used in metal removal and forming operations. For end use, formulation concentrates are diluted in water, providing conditions conducive to microbial growth and metabolism and potentially causing fluid biodeterioration and microbiologically influenced corrosion. Microorganisms in the environment are highly diverse, and bacteria and fungi have been recovered from these fluids at population densities of >10 6 CFU mL À1. Thus, to control microbial bioburdens in MWFs, microbicides are often incorporated into MWF formulations, used as tankside additives, or both. Some microbicides are suspected as being responsible for adverse health effects. Consequently, their usage has been restricted in recently adopted regulations. Given the limited number of microbicides currently approved for use in MWFs, alternative microbial contamination control strategies are needed. Some of these strategies have already been employed in the market. Studies on microorganisms in MWFs are often hindered by the complexity of the media, especially when trying to examine in-use samples. Historically, microbiological analyses were primarily based on cultivation assays using nutrient-rich media. These analyses have severe disadvantages, and the adoption of more reliable test methods is of utmost importance. Here, we review MWF microbiology, discussing possible consequences and options for both control and condition monitoring testing.
