PURPOSE:To obtain a molded adsorbent body for a water purifier which can be easily regenerated by heating with hot water or high temp. steam by kneading fibrous activated carbon, specified phenol resin and water, molding, and carbonizing. CONSTITUTION:This molded adsorbent body has a molded body 3 obtd. by mixing fibrous activated carbon 2, powder or fibrous phenol resin, and water, then molding, and carbonizing. The phenol resin has >=3000 average mol.wt. without containing isolated phenol and has hot-melt property and solubility with a solvent. This molded body 3 is housed in a case 1 equipped with an inlet 4 and exit 5 for water on the upper and lower ends and is used to adsorb and remove trihalomethane, odorous component such as odor of mold, and isolated chlorine in city water during water is passed through the cartridge. When the purification ability decreases, the cartridge is regenerated by heating with hot water or high temp. steam. |
