| Abstract |
This study characterized the flow of particulate material and organic material in the pipeline used in a distribution system of a semiconductor ultrapure water production process. Polyvinylidene fluoride (PVDF) pipes were used in this study. They were filled with ultrapure water to measure the flow of particulate and organic material under static conditions. For a dynamic test, a pilot plant was built and tested for particulate and organic materials. The dynamic test was conducted twice with a minimum velocity of 0.91 m/s and a maximum velocity of 2.13 m/s according to American Society for Testing and Materials (ASTM) standards. Particulate and organic substances flowed out according to the change of velocity. Particulate material was measured using a nanoparticle tracking analyzer (NTA) and organic material was measured using total organic carbon (TOC). Results of both static and dynamic experiments showed similar trends in particulate and organic fluxes. In the case of dynamic experiments, particulate and organic material fluxes increased as the velocity increased while sizes of flushed particles decreased. Results of this study suggest that it is possible to estimate the particulate material outflow as the velocity changes during ultrapure water plant operation. |
