“…Among these, Achromobacter, Citrobacter, Pseudomonas, and Staphylococcus were the major genera identified in the water-soluble cutting fluid. Among the isolated bacteria, Achromobacter xylosoxidans has been isolated from hospitals, homes, and water, has been reported to produce foul odors, and is infectious to humans [26][27][28][29][30], whereas Citrobacter farmeri has been reported to cause illness in humans and is also known to produce foul odors [31][32][33]. Strains of Pseudomonas chengduensis have been found in humans (disease), animals, waste cooking oil, and landfills and have been reported as odor-causing bacteria, similar to other bacteria.…”

Odor and discoloration in water-based cutting fluids are caused by the growth of microorganisms and putrefying bacteria. This significantly reduces cutting performance, prevents rust, and deteriorates the working environment. To overcome these drawbacks, we developed a compact air-cooled coaxial dielectric barrier discharge (DBD) with a bubbler. Bacteria and microorganisms living in waste cutting fluids were sterilized by the high concentration of ozone produced under the optimized conditions of the compact air-cooled coaxial DBD. Moreover, it was confirmed that 99.99% of bacteria and microorganisms were completely removed. Ozone was found to not affect property changes such as the composition, concentration, and pH of the water-based cutting fluids. The chromaticity and complex odor of waste cutting liquids were thus found to have been improved by the effects of microorganism and bacterial sterilization. We conclude that the proposed a compact air-cooled coaxial DBD with a bubbler is an efficient method for sterilizing water-based cutting fluids.
