Abstract
The purpose of this study is to evaluate the field applicability of Quantum Stick in scale deposit prevention for subway tunnels in Seoul. This technology was installed into drainpipes and its performance was monitored through occasional site visits. SEM and EDS were also performed on scale collected from these drain pipes. Results showed a decrease in scale deposits due to Quantum Stick treatment. In the field test, the device was found to be effective in preventing scale formation in new pipes as well as reducing existing scale in previously installed pipes. However, further investigations are necessary to account for various environmental conditions. In conclusion, the results indicate that molecular Vibration technology is effective in suppressing scale formation.
