Abstract: The present invention relates to a zinc ion water treatment device comprising: a zinc block having a plurality of through holes in the body thereof; and a fluororesin block having another plurality of through holes, wherein the side surface of the fluororesin block is provided in concave and convex forms.

Abstract: An apparatus for electric treatment of fluid is provided. When heavy metal ions or a colloid carrying a positive charge is present in fluid traveling through metal pipework, a negative electrode is formed using a metal component having high ionization tendency, a positive electrode is formed using a metal component having ionization tendency lower than that of hydrogen, and an insulating layer is formed between the positive and negative electrodes. When conductive fluid passes through the positive electrode and the negative electrode, direct electrical power is applied to make the negative electrode emit electrons, which react with heavy metal ions present in the conductive fluid, thereby reducing the heavy metal ions. The metal component of the negative electrode emits electrons when ionized based on its ionization tendency and via an electrostatic action. Much more electrons are emitted compared to existing fluid treatment systems, and positive charges are removed more efficiently.

Abstract: The present invention relates to a water purifier of tap water. According to the present invention, a metal having a higher ionization tendency is ionized by exposing the metal to water to be purified. The metal having a higher ionization tendency is selected based on iron (Fe) and limited to metals having a higher ionization tendency as compared with iron (Fe). Electrons generated when a metal is ionized into water react with heavy metal ions that have already existed in the water to reduce the heavy metal ions. The heavy metal ions react with the electrons and are converted into heavy metal components. The heavy metals are pulled by magnets with a strong magnetism and removed from the water safely. When using a water purifier according to the present invention, users can drink water useful to the human body safely and hygienically since mineral components dissolved into water are not removed at all while removing the heavy metals although small quantities of heavy metals are dissolved into water.
