Abstract

Treatment with an electromagnetic field, one of the potential techniques to inhibit scale deposition from water, has the advantage of not requiring the addition of any chemicals. Field tests using a fibre optic sensor were conducted to evaluate the effect that the treatment of hot spring water in Matsushiro, Japan with an electromagnetic field had on calcium carbonate scale formation. The optical response to scale deposition recorded by the fibre optic sensor decreased as a consequence of the application of an electromagnetic field, and the effectiveness of scale formation inhibition depended on the frequency of the electromagnetic field. This evidence was compared with results from changes in scale mass measured using the quartz crystal microbalance (QCM) method. Mass increases of the scale formed on the quartz crystal surface in hot spring water were inhibited by electromagnetic field treatment. These results were verified performing a column flow test, whereby the flow rate of hot spring water through a column was measured.

摘要

磁场处理是抑制水中结垢的潜在技术之一，其优点是无需添加任何化学物质。本研究采用光纤传感器进行现场测试，以评估日本松代温泉水中磁场处理对碳酸钙结垢形成的影响。光纤传感器记录的结垢沉积光学响应随着磁场的应用而降低，结垢抑制效果取决于磁场的频率。这一证据与使用石英晶体微天平（QCM）方法测量的结垢质量变化的结果进行了比较。磁场处理抑制了温泉水中在石英晶体表面形成的结垢的质量增加。通过柱流测试验证了这些结果，该测试测量了温泉水通过柱的流速。
