| Summary: | 碩士 === 嘉南藥理科技大學 === 溫泉產業研究所 === 97 === It is common that hot-spring wells exhaust gas in Taiwan, causing errors on the facilities measuring water quantities. Furthermore, the gas can be pernicious. It’s critical to solve these two problems.
This paper discussed degas and measuring facilities of water quantities on the following 5 sites: Hsinchu-Cingcaohu, Taipei-Bali, Taipei-Hsinchuang, Hsinchu-Chienshih and Taipei-Jinshan hot-spring wells. By measuring the testing of the measuring facilities on the error scale and degas effects, some suggestions can be made for improvement.
The case studies have shown that, because degas equipment is not properly installed, the error range of the measurement is about 25% ~ 140%, hence the total exhausted gas is merely about 1% ~ 58% of all, less than acceptable expectation. Using hot-spring water into the storage tank to extend the hydraulic retention time, 99.96% of degas could be reached, and gas dissolved in the water by volume is as low as negligible extent.
It is concluded that, by adjustment of the degas facilities on hot-spring well and measurement methods, measurement error can be evidentially reduced, and the safety for customers of spa environments are ensured.
