Abstract: Disclosed is a water treatment apparatus including a pipe. Elements disposed in the pipe are respectively made of lead-free brass and nontoxic ultra high molecular weight polyethylene instead of brass and plastic polyethylene that are conventionally used materials. Therefore, when the elements come into contact with water, neither heavy metals, such as lead (Pb), nor organic and inorganic substances harmful to the human body are produced.

Abstract: Disclosed is an ionization water treatment apparatus using a carbon nanotube. In the ionization water treatment apparatus, water flowing through the tubular body is ionized and activated due to the potential difference, and a filter is constructed in such a manner that the water makes contact with the carbon nanotube to perform an antibacterial function and a function of adsorbing heavy metal, so that the structure thereof is simplified, a superior antibacterial effect and superior ionization performance are represented, and rust is prevented in a tubular body due to the removal of foreign matters. The filtering member is constructed in such a manner that the contact area between the water passing through the tubular body and a filter is maximized, so that efficiency is more increased in an antibacterial function and in the removal of foreign matters when water passes through a filtering member.

Abstract: Disclosed is an ionization water treatment apparatus. The ionization water treatment apparatus includes an electrostatic field generating element generating an electrostatic field, an insulating tube receiving the electrostatic field generating element and blocking temperature transmission between inner and outer parts of the insulating tube, a finishing element preventing water from flowing into the insulating tube, a housing receiving the insulating tube and the finishing element, and a housing connector coupled with the housing at one side of the housing connecting member. The electrostatic field generating element includes a metallic electrode, two carbon electrodes arranged at both sides of the metallic electrode, and a pipe assembling the carbon electrodes with the metallic electrode. The carbon electrode reacts with gas including fluorine (F2) at a predetermined temperature so that a surface of the carbon electrode is treated.
