AIR PURIFICATION DEVICE, FILTER FOR PURIFYING AIR, WATER PURIFICATION DEVICE, AND CARTRIDGE FOR PURIFYING WATER

摘要

PROBLEM TO BE SOLVED: To provide a water purification device which can exhibit a water purification function sufficiently even when a filtration flow rate is high and in which such a problem is hardly caused that a porous carbon material leaks from a water purifier together with purified water.;SOLUTION: The water purification device includes a column or a cartridge in which the porous carbon material is packed, which material has 1×10² m²/g or larger specific surface area when measured by a nitrogen BET method, 0.3 cm³/g or higher pore volume when measured by the BJH method, and 75 μm or larger particle diameter. The bulk density of the porous carbon material is from 0.1 g/cm³ to 0.8 g/cm³.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
