초록
Scale generation in the inside of a pipe IS restricted by reduction and oxidation(REDOX) reaction of alloyed metal of Cu-Zn. To measure the scale generating rate in the 1.67 mm of inside diameter of stainless steel tube, 300 ppm of CaCO3 solution is circulated in the REDOX reactor and stainless steel tube in the order. In the case of CaCO3 solution treated by REDOX reactor, flowing is maintained without plugging in the stainless steel tube, and the concentration of Cu and Zn in the circulating solution showed less than 1 ppm, which is equal to that of untreated by REDOX reactor. The crystal type of CaCO3 generated by crystalline nucleus of Cu or Zn, mostly showed aragonite type.
