Filter-Less Purification of a Water-Soluble Coolant by Using PGA Based Flocculants and Microbubbles

Abstract:

In grinding processes, water-soluble working fluid is in heavy usage to maintain and improve a grinding performance. In this paper, effects of the water quality (soft or hard) were studied in a new filter-less purification system using commercially available Polyglutamic acid based flocculants and the microbubble coolant at the same time. As a result of the experiments, it was found that the collection rate of the suspended matters by the magnetic adsorption removal for the hard water became lower compared to the soft water, due to the Ca component contained in rich. It has also been made clear that by removing the suspended matters in the fluid flocked by the flocculant using the magnetic adsorption method and overflowing the residue with the microbubbles after that, the collection rate of the suspended matters in the soft water fluid would become higher than 99%. In the case of the hard water as well, improvement of the collection rate by the microbubbles was confirmed.
