Abstract

Disclosed is a scale treatment apparatus for changing structures of water and various mineral materials in a pipe and supplying activation energy, thereby preventing the accumulation of, as well as removing, amorphous CaCO₃ or sediment in the pipe. This scale treatment apparatus includes: an interrupted direct current supply unit for alternately outputting low-frequency interrupted direct current and high-frequency interrupted direct current at a predetermined time interval; and a magnetic field generation unit provided to the pipe while being connected to the interrupted direct current supply unit such that an intermittently vibrating electromagnetic field is generated by low-frequency interrupted direct current and high-frequency interrupted direct current, which are alternately output from the interrupted direct current supply unit, and is then applied to the pipe, wherein the interrupted direct current supply unit includes a power supply circuit to which direct current power is supplied, a basic frequency oscillation circuit connected to the power supply circuit, a low-frequency oscillation circuit and a high-frequency oscillation circuit, connected to the basic frequency oscillation circuit, an interrupted direct current circuit connected to the low-frequency oscillation circuit and the high-frequency oscillation circuit such that a low frequency emitted from the low-frequency oscillation circuit is converted into low-frequency interrupted direct current and a high frequency emitted from the high-frequency oscillation circuit is converted into high-frequency interrupted direct current, and an alternate output circuit connected to the interrupted direct current circuit such that low-frequency interrupted direct current and high-frequency interrupted direct current, which are applied, are alternately output at a predetermined time interval.
