Water purifier
Disclosed is a water purifier including a first storage cistern in which an inlet for flowing in water is formed, a second storage cistern for storing the purified water and having a nozzle at the outside thereof, and a filter constituted by a ceramic filter, a cartridge filter, and a mineral filter and installed to the inside of the first storage cistern and the second storage cistern to filter the water flown in the first storage cistern and make the purified water flow in the second storage cistern, the water purifier comprises a ceramic filter formed as a mixture by mixing the conventional used silicon dioxide with its particle size of 1˜100 micrometer with additionally one or two or more selected among silicon dioxide, tungsten, alumina (Al 2 O 3 ), silver, zinc (Zn), white gold (PT), gold (Au), and titanium dioxide (TiO 2 ) with nano particle size.
1. In a water purifier including a first storage cistern in which an inlet for flowing in water is formed, a second storage cistern for storing the purified water and having a nozzle at the outside thereof, and a filter system comprising a ceramic filter, a cartridge filter, and a mineral filter installed in the first storage cistern and the second storage cistern to filter water in the first storage cistern and make the purified water in the second storage cistern,
the ceramic filter formed from a mixture of (a) conventional used silicon dioxide with particles size of 1-100 micrometer and (b) nanoparticles comprising silicon dioxide, tungsten, alumina, and titanium dioxide, wherein each particle size and concentration of the nanoparticles in the mixture within the ceramic filter are as follows:
the particle size of the silicon dioxide nanoparticles is 1-100 nanometer and its use concentration is 10-1000 ppm, the particle size of tungsten nanoparticles is 0.5-50 nanometer and its use concentration is 1-500 ppm, the particle size of alumina nanoparticles is 1-100 nanometer and its use concentration is 50-500 ppm, and the particle size of the titanium dioxide nanoparticles is 1-100 nanometer and its use concentration is 50-500 ppm; and
the cartridge filter comprising a silver-coated carbon filter, wherein the silver coated on the surface of the carbon filter is formed by silver nanoparticles with the size of 1-10 nanometer and coated in a concentration of 5-150 ppm.
2. The water purifier of claim 1 , wherein the mineral filter is installed at the bottom of the second storage cistern, wherein silver (Ag), platinum, (PT), and gold (Au), are mixed selectively with mineral to form the mineral filter, wherein the particle size of silver (Ag) is 1-10 nm (nanometer) and its use concentration is 50-200 ppm, the particle size of platinum (PT) is 1-50 nm (nanometer) and its used concentration is 1-10 ppm, and the particle size of gold (Au) is 1-20 nm (nanometer) and its use concentration is 1-10 ppm.
