円筒体７と容器１０の内壁面との間には活性炭１８が配備され、リング状のフィルター９ａ、９ｂ間で吸着剤層１９が形成されている。 Activated carbon 18 is disposed between the cylindrical body 7 and the inner wall surface of the container 10, and an adsorbent layer 19 is formed between the ring-shaped filters 9a and 9b.

実施例１
吸着剤層に、ヤシ殻を原料とする半径が７〜１５オングストロームの微細孔を有し、かつ該微細孔の容積が全細孔容積の４５％を占める粒状活性炭であって、該粒状活性炭は粒径が０．１〜１ｍｍの粒径を有する粒子群の質量が、全粒子質量の９０％であるものを５０ｃｍ³充填した。 Example 1
The adsorbent layer was packed with 50 cm3 of granular activated carbon made from coconut shells, which had micropores with a radius of 7 to 15 angstroms and the volume of the micropores accounted for 45% of the total pore volume, and in which the mass of particles having particle diameters of 0.1 to 1 ^mm accounted for 90% of the total particle mass.

実施例２
次に、吸着剤層に１５０ｍｌの前記活性炭を充填し、濃度が１００ｐｐｂのトリハロメタン（クロロホルム４５ｐｐｂ、ブロモジクロロメタン３０ｐｐｂ、ジブロモクロロメタン２０ｐｐｂ、ボロモホルム５ｐｐｂ）と２ｐｐｍの遊離塩素を含む試験水を２リットル／ｍｉｎで通水し、濾過された浄化水のトリハロメタン濃度が２０ｐｐｂ以上になるまでの総通水量を測定したところ、２，４８０リットルであった。なお遊離塩素は常に９０％以上除去されていた。 Example 2
Next , 150 ml of the activated carbon was packed into the adsorbent layer , and test water containing 100 ppb of trihalomethanes (chloroform 45 ppb, bromodichloromethane 30 ppb, dibromochloromethane 20 ppb, bromoform 5 ppb) and 2 ppm of free chlorine was passed through at 2 liters/min. The total amount of water passed through until the trihalomethane concentration of the filtered purified water reached 20 ppb or more was measured, which was 2,480 liters. Furthermore, more than 90% of the free chlorine was always removed.

さらに、請求項１の発明は、一日あたり１０リットルの浄化水を使用するとした場合、浄水器のトリハロメタン除去寿命を２ヶ月以上とすることができ、頻繁に交換する必要がなく便利であるという特有の効果を奏する。請求項２の発明は、寿命時期に達した該濾過部を新品濾過部へ交換するに際して経済的であり、かつ交換作業が非常に容易であるという特有の効果を奏する。 Furthermore, the invention of claim 1 has the unique advantage that the trihalomethane removal life of the water purifier can be extended to 2 months or more when 10 liters of purified water is used per day, eliminating the need for frequent replacement. The invention of claim 2 has the unique advantage that it is economical and very easy to replace the filter unit that has reached the end of its life with a new one.
