1)Diagram of Water Flow Sediment Filter Pre-treatment Sediment Filter maximized the effect of purification from the initial stage by eliminating minute impurities with the size down to 1 μm such as rust, soil, sand and dust. Pre-Carbon Filter Pre-Carbon Filter that used absorption method of carbon makes water, which is close to natural water by absorption and elimination of organic chemicals such as chlorine ingredient (tri-halo-methane) and smell as well. Ultra-Filtration Filter Minute Ultra-Filtration Filter with the size of 0.1~0.4 μm thoroughly filters the impurities still existing in water and passes only clean water, which contains original mineral ingredients. Post Carbon Filter Post Carbon Filter makes clean water without color and taste by preventing the propagation of bacteria and eliminating unpleasant smell, taste and pigments permeated in water.     UF Membrane Filter   Membrane UF Filter is a filter, which is appropriate for the separation of the substance with low molecular weight and the substance with high molecular and colloidal status, and eliminates pollutants in water through countless minute stigmata distributed on the surface of membrane. Membrane UF Filter is a filter with superior performance, which is used for a variety of application from home water purifier to the treatment of industrial sewage and wastewater, super-pure manufacturing process and artificial kidney machine for medical use. Minute Membrane UF Filter with the size of 0.01~0.04 μm eliminates impurities and pollutants while passing original mineral ingredients. The Membrane UF Filter has superior medicine durability and thermal resistance as it used Polysulfone as membrane material
