电磁场处理是抑制水中水垢沉积的潜在技术之一，其优点是不需要添加任何化学品。使用光纤传感器进行现场测试，以评估在日本松代的温泉水的处理与电磁场对碳酸钙垢形成的影响。由光纤传感器记录的对垢沉积的光学响应由于电磁场的应用而降低，并且垢形成抑制的有效性取决于电磁场的频率。这一证据进行了比较，从使用石英晶体微量天平（QCM）方法测量的规模质量的变化的结果。电磁场处理抑制了温泉水中石英晶体表面结垢的质量增长。通过测定温泉水通过柱的流量的柱流动试验，对上述结果进行了验证。
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.
