요소기술을 이용한 스케일 생성 억제기술의 지하철 터널 내 현장 적용성 평가

Abstract

The purpose of this study is to evaluate the field applicability of Quantum Stick in scale deposit prevention for a subway tunnel in Seoul. This technology was installed into drain canals and its performance was monitored through occasional site visits. Scanning electron Microscope and Energy Dispersive Spectroscopy were performed on scale collected from these drain canals. Results showed a decrease in scale deposits due to Quantum Stick treatment. In the field the device was found to be effective in preventing scale formation in drainage canals as well as reducing existing scale in previously installed drianage canals. However, further investigations are necessary to account for various environmental conditions. In conclusion, the results indicate Quantum Stick treatment is effective in preventing scale formation.
